Keep Folders Hidden
first create a new folder somewhere on your hard drive
when you name it hold down "Alt" and press "0160" this will create and invisible space so it will appear as if it has no name.
then right click in and select "Properties" select the tab "customize" and select "change icon" scroll along and you should a few blank spaces click on any one and click ok when you have saved the settings the folder will be invisible to hide all your personal files.
Keep Files Private
If you want to encrypt the contents of an individual file or directory, Windows XP Pro will do the trick, provided you enable NTFS on your hard drive. To encrypt a file, right-click on it to bring up the Properties window. Click on the Advanced button, then in the Advanced Attributes dialog box click on Encrypt contents to secure data. This will encrypt the file (using either DES, which employs a 56-bit key on each 64-bit block of data, or 3DES, which uses a 56-bit key three times on each 64-bit block of data), and it will provide a certificate just for you. This certificate is key; if you reinstall Windows or otherwise lose your user account, your access to the encrypted files will be gone, too. You need to export your certificates to back them up: For detailed instructions, search on export certificate in Windows Help.
Windows XP does not require you to enter your password when you open the encrypted file. Once you log on to a session, encrypted files are available for you—and anyone who walks up to your system—to view.
Windows XP Home doesn't support this method. Both XP Home and XP Pro, however, let you create password-protected compressed files. To do this, right-click on the desired file and choose Send To | Compressed (zipped) Folder. Open the resulting folder and select Add a Password from the File menu; delete the original file. Note that this encryption is relatively weak. It should dissuade casual users but won't put up much of a fight against someone determined to hack it apart.

how to search google for RAPIDSHARE links
If you wanna find some apps, files etc on rapidshare.de via google, do the following.
Paste this into the google search window (not the adress bar):
site:rapidshare.de -filetype:zip OR rar daterange:2453402-2453412
* this searches the site rapidshare.de for any file that is rar or zip, and
has been indexed between 1-11 February.
dvd site:rapidshare.de -filetype:zip OR rar daterange:2453402-2453412
* this is the same search but it specifically searches for "dvd" with the same
search criteria, so any app posted with the word dvd in it will be found.
There are mainly three criteria to keep in mind when doing this search.
1. site: your site of choice to search
2. filetype: filetypes you wanna search,if you put a "OR" after the first
filetype you can add more.
When Good Discs Go Bad
Ever wonder what makes a disc bad? Here's why they vary in quality, and why you should worry about the discs you've entrusted with your data.
Burning CDs and DVDs is the easy part.
Knowing your data will be there when you go back to it days, months, or even years later--well, that's a bit harder. Not all discs are created equal, as Fred Byers, information technology specialist at the National Institute of Standards and Technology, can attest.
Byers is part of a team heading up an independent study of DVD media quality. Based on the first wave of testing results, the situation is murky at best.
"We've found the quality varies, depending upon the type of dye used to make the write-once discs and [on the] the manufacturer," reports Byers. Even discs from the same manufacturer, with the same brand, can test differently, Byers adds. "But there was more of a significant difference when you compared discs between manufacturers," he explains.
DVD Media Quality: The First Tests
In the first phase of testing, completed late last year, NIST focused on the most popular media: write-once, single-layer DVD-R and +R discs. Rewritable discs will be tested in the second phase, slated to start this fall. An interesting footnote to the study's methodology: NIST uses media purchased off store shelves and via Web sites; and while researchers are tracking the media by brand, they are not tracking the specific factory source of the media tested. For example, a given manufacturer's discs could originate from different production lines, which could account for a variation in disc quality by the same manufacturer.
Hearing that there's a difference between the generic, unbranded 100-spindle value-pack of media purchased online and the branded offerings you might find on a Best Buy store shelf is not surprising. After all, as David Bunzel, president of the Optical Storage Technology Association, points out: "With a generic product, there's no consumer recourse. It's buyer beware."
If a disc isn't properly manufactured, the consequences can be dire. At best, the disc will fail immediately during the burn process; this is a best-case scenario because then you know from the start that the disc is faulty. At worst, you may get an abundance of errors during the burn process. These errors won't interrupt the burning process, and since write-once and rewritable DVD media have built-in error correction to compensate for scratches and other abnormalities on the disc (as do their CD cousins), any errors will be virtually invisible to you. You'll only know they're there if you use a disc diagnostics program, such as those offered by Ahead Software or Plextor. Nor will these errors affect the playback of the disc--initially.
Down the road, however, such invisible-to-the-eye errors can reduce the effectiveness of a DVD's built-in error correction so that if some other issue develops on your disc, such as a scratch, you could end up with an unreadable disc when you go back to it months or years later.
But what would cause such a wide disparity in media quality between branded discs from the same vendor?
"We don't know why it's different--it could be a different dye, it could be a different manufacturing process," notes Byers. "Manufacturers are constantly trying to improve their dye formulas--in theory improving the disc."
Nonetheless, at the same time, competitive forces are driving manufacturers to find ways to economize on production costs. And cost-cutting measures can result in discs that don't perform as well as those generated during an earlier production run, either in terms of failing outright or not burning at the maximum possible speed on a given DVD drive. "It varies over time, as the output changes," Byers says.
Brand Disparity
As for the disparity between brands that NIST found, the distinguishing factors come down to quality control and the dyes used in disc production. Declining to name names, Byers points out that "some manufacturers make their own discs, and some purchase them from someplace else--which opens you to variations in the manufacturing plant, or changes in the source [of that media]."
Vendors like Maxell and Verbatim manufacture discs on their own production lines, as do Asian manufacturers CMC Magnetics, RiData, Taiyo Yuden, and others; other name brands contract with a third-party manufacturer to produce discs to their own specs; and still others just buy third-party-produced media wholesale, without imposing their own set of quality controls on the media production.
The intricacies of disc production and quality control aren't the only variables that seem to affect media. More surprising is the number of discs that seem to have a propensity for specific hardware.
"One thing we've found in compatibility testing [of DVD-R and +R media] is that it's a relationship between a specific brand of media and the manufacturer of the hardware," observes Byers. "There was no one drive that played every single type of compatible media, and there was no one media brand that played perfectly in every drive."
And, he adds, sounding as frustrated as any consumer might, "You can't say there's a clear, delineated set of reasons as to why."
A Grading System?
One of the most common questions I hear is, "What's a good brand of media to buy?" DVD and CD media are so commonplace nowadays that it's easy to forget the complexities that go into producing them. And if anything in that production process is off, it could, in time, affect the integrity of the data you've burned to a disc.
"It's very tough to answer that kind of question, because there are so many variables," says Byers. "You don't get 100 percent yield when you manufacture these discs. We can talk about the materials that produce a good disc, but it also has to do with the manufacturing process. So, just to say the materials to look for doesn't necessarily relate to it being a better disc." The same is true vice versa.
So how can you know that the media you're using will last you for the duration, so those archived photos will still be there when you go back to a disc 20 years from now--or more?
For the moment, you can't. All DVD and CD vendors make vague claims about disc life expectancy being somewhere between 60 and 100 years--when the discs are treated with care and stored properly.
But NIST's Byers is seeking to change that. At an OSTA meeting in San Francisco this week, Byers is proposing an industry-wide grading system to indicate disc quality.
Byers is motivated by the desire to see a uniform mechanism in place to guide institutions and individuals who'll be storing data, music, videos, and images for long periods of time. "They need to be confident in their purchasing, so they can plan for their strategies in storing their information," Byers says. "Long-term storage has different meanings: For some, 30 years might be enough. For others, 50 or 75 years might be archive, or long-term, quality."
Longevity
Under Byers's proposal, a series of tests would be developed to determine whether a DVD would last for a given number of years. "If you were to purchase a disc in a store with a grade that indicates it has passed a test to last X number of years, it removes a lot of uncertainty for the consumer, and it can save some expense in premature migration [to a new storage technology], or loss of data because they waited too long [and the disc was no longer playable]," he says.
Although some archivists--both individual and professional--are concerned about whether today's digital storage mediums will be readable 50 or 100 years from now, Byers believes the bigger concern for users will be when to migrate their data to the next technology, "before the existing technology is obsolete."
The Disc Rot Myth
Media obsolescence isn't the only thing people fear after committing a personal library's worth of data to CDs and DVDs. But some worries--namely, fear of disc rot--are not fully warranted.
Like a bad seed, the myth of disc rot self-perpetuates, cropping up every now and again as a sudden and mortal threat to your copious collection of prerecorded and self-created discs.
The myth was once rooted in fact. It is true that back in the 1980s, with the first generation of prerecorded audio CDs, the edges of the discs were not always sealed properly, which allowed moisture to get into the disc. Replicated, prerecorded discs use aluminum for the reflective layer; when moisture came into contact with the aluminum on prerecorded discs, explains Byers, it in turn oxidized, causing the aluminum to become dull. "That's where the term 'rot' started," he says.
But that problem was quickly identified and overcome. "The manufacturers learned what was going on, so now the edges of discs are sealed with a lacquer," according to Byers. Though the problem is typically associated with CDs, Byers notes that the potential for interaction with oxygen is the same with both CD-ROMs and DVD-ROMs.
The so-called rot issue does not apply to recordable discs. For one thing, recordable optical media do not use aluminum; instead, they use silver, and very rarely gold, or a silver-gold alloy, for the reflective layer. "If the silver comes into contact with sulfates [i.e., pollution, or high humidity], it could affect the silver, but the likelihood of that is less than the likelihood of moisture coming into contact with the aluminum on prerecorded discs," says Byers.
Enduring Myth
The term rot has persisted, however inaccurately, as a means of identifying a plethora of problems with optical discs. "If you get a faulty disc and see a problem that you can visually see, you call it rot, but it could be the way the disc was manufactured," says Byers. "Or if it was subjected to extreme moisture and that moisture came into contact with the aluminum, it could be that the reflectivity has changed. It's not really rot, it's oxidation of aluminum. It should be a rare event on a disc, unless it's defective."
Beyond the realm of defective discs, improper handling can cause otherwise good discs to go bad. Since there's little protection between the label side of a CD and the data layer itself, "scratches on the label side can scratch the metal, and that will ruin the data," says Byers. It's not an issue for DVDs, though, since the dye layer is sandwiched between two plastic layers.
Byers observed a similar problem occurring with press-on labels: "For long-term storage, we recommend not using press-on labels on CDs; when these start to dry up, they can peel the metal right up, damaging data."
Change the CHKDSK countdown time
When you schedule CHKDSK to run at the next boot, the system will prompt you to press a key to cancel the operation while CHKDSK is running. The system will display a countdown during that cancel period. The default value is 10 seconds. To Change this open up Regedit and locate:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\AutoChkTimeOut
You can change the value to anything from zero to 259,200 seconds (3 days). With a timeout of zero, there is no countdown and you cannot cancel the operation
--ACRONYMS--
DOS = Disk Operating System, or MS-DOS
MSIE = Microsoft Internet Explorer
TIF = Temporary Internet Files (folder)
HD = Hard Drive
OS = Operating System
FYI = For Your Information
1)SEEING IS BELIEVING
No. Enabling Windows Explorer to "show all files" does not show the files in mention. No. DOS does not
list the files after receiving a proper directory listing from root. And yes. Microsoft intentionally
disabled the "Find" utility from searching through one of the folders.
Oh, but that's not all.
To see for yourself simply do as you would normally do to clear your browsing history. Go to Internet
Options under your Control Panel. Click on the [Clear History] and [Delete Files] buttons. (Make sure
to include all offline content.)
So, has your browsing history been cleared? One would think so.
These are the names and locations of the "really hidden files":
c:\windows\history\history.ie5\index.dat
c:\windows\tempor~1\content.ie5\index.dat
If you have upgraded MSIE several times, they might have alternative names of mm256.dat and
mm2048.dat, and may also be located here:
c:\windows\tempor~1\
c:\windows\history\
Not to mention the other alternative locations under:
c:\windows\profiles\%user%\...
c:\windows\application data\...
c:\windows\local settings\...
c:\windows\temp\...
c:\temp\...
(or as defined in your autoexec.bat.)
FYI, there are a couple other index.dat files that get hidden as well, but they are seemingly not very
important. See if you can find them.
2)IF YOU HAVE EVER USED MICROSOFT INTERNET EXPLORER
1) Shut your computer down, and turn it back on.
2) While your computer is booting keep pressing the [F8] key until you are given an option screen.
3) Choose "Command Prompt Only" (This will take you to true DOS mode.) Windows ME users must use a boot
disk to get into real DOS mode.
4) When your computer is done booting, you will have a C:\> followed by a blinking cursor.
Type this in, hitting enter after each line. (Obviously, don't type the comments in parentheses.)
C:\WINDOWS\SMARTDRV (Loads smartdrive to speed things up.)
CD\
DELTREE/Y TEMP (This line removes temporary files.)
CD WINDOWS
DELTREE/Y COOKIES (This line removes cookies.)
DELTREE/Y TEMP (This removes temporary files.)
DELTREE/Y HISTORY (This line removes your browsing history.)
DELTREE/Y TEMPOR~1 (This line removes your internet cache.)
(If that last line doesn't work, then type this
CD\WINDOWS\APPLIC~1
DELTREE/Y TEMPOR~1
(If that didn't work, then type this
CD\WINDOWS\LOCALS~1
DELTREE/Y TEMPOR~1
If you have profiles turned on, then it is likely located under \windows\profiles\%user%\, while older
versions of MSIE keep them under \windows\content\.)
FYI, Windows re-creates the index.dat files automatically when you reboot your machine, so don't be
surprised when you see them again. They should at least be cleared of your browsing history.
3)CLEARING YOUR REGISTRY
It was once believed that the registry is the central database of Windows that stores and maintains the
OS configuration information. Well, this is wrong. Apparently, it also maintains a bunch of other
information that has absolutely nothing to do with the configuration. I won't get into the other
stuff, but for one, your typed URLs are stored in the registry.
HKEY_USERS/Default/Software/Microsoft/Internet Explorer/TypedURLs/
HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/TypedURLs/
These "Typed URLs" come from MSIE's autocomplete feature. It records all URLs that you've typed in manually
in order to save you some time filling out the address field.
4)SLACK FILES
As you may already know, deleting files only deletes the references to them. They are in fact still sitting
there on your HD and can still be recovered by a very motivated person.
Use window washer to delete slack files. /http://www.webroot.com/download/0506/reg3ww.exe
5)STEP-BY-STEP GUIDE THROUGH YOUR HIDDEN FILES
The most important files to be paying attention to are your "index.dat" files. These are database files
that reference your history, cache and cookies. The first thing you should know is that the index.dat files
is that they don't exist in less you know they do. They second thing you should know about them is that
some will *not* get cleared after deleting your history and cache.
To view these files, follow these steps:
In MSIE 5.x, you can skip this first step by opening MSIE and going to Tools > Internet Options > [Settings] > [View Files].
Now write down the names of your alphanumeric folders on a piece of paper. If you can't see any alphanumeric
folders then start with step 1 here:
1) First, drop to a DOS box and type this at prompt (in all lower-case). It will bring up Windows Explorer
under the correct directory.
c:\windows\explorer /e,c:\windows\tempor~1\content.ie5\
You see all those alphanumeric names listed under "content.ie5?" (left-hand side.) That's Microsoft's
idea of making this project as hard as possible. Actually, these are your alphanumeric folders that was
created to keep your cache. Write these names down on a piece of paper. (They should look something like
this: 6YQ2GSWF, QRM7KL3F, U7YHQKI4, 7YMZ516U, etc.) If you click on any of the alphanumeric folders then
nothing will be displayed. Not because there aren't any files here, but because Windows Explorer has lied
to you. If you want to view the contents of these alphanumeric folders you will have to do so in DOS.
2) Then you must restart in MS-DOS mode. (Start > Shutdown > Restart in MS-DOS mode. ME users use a
bootdisk.)
Note that you must restart to DOS because windows has locked down some of the files and they can only be
accessed in real DOS mode.
3) Type this in at prompt:
CD\WINDOWS\TEMPOR~1\CONTENT.IE5
CD %alphanumeric%
(replace the "%alphanumeric%" with the first name that you just wrote down.)
DIR/P
The cache files you are now looking at are directly responsible for the mysterious erosion of HD space
you may have been noticing.
5) Type this in:
CD\WINDOWS\TEMPOR~1\CONTENT.IE5
EDIT /75 INDEX.DAT
You will be brought to a blue screen with a bunch of binary.
6) Press and hold the [Page Down] button until you start seeing lists of URLs. These are all the sites
that you've ever visited as well as a brief description of each. You'll notice it records everything
ou've searched for in a search engine in plain text, in addition to the URL.
7) When you get done searching around you can go to File > Exit. If you don't have mouse support in DOS
then use the [ALT] and arrow keys.
Next you'll probably want to erase these files by typing this:
C:\WINDOWS\SMARTDRV
CD\WINDOWS
DELTREE/Y TEMPOR~1
(replace "cd\windows" with the location of your TIF folder if different.)
9) Then check out the contents of your History folder by typing this:
CD\WINDOWS\HISTORY\HISTORY.IE5
EDIT /75 INDEX.DAT
You will be brought to a blue screen with more binary.
10) Press and hold the [Page Down] button until you start seeing lists of URLS again.
This is another database of the sites you've visited.
11) And if you're still with me, type this:
CD\WINDOWS\HISTORY
12) If you see any mmXXXX.dat files here then check them out (and delete them.) Then:
CD\WINDOWS\HISTORY\HISTORY.IE5
CD MSHIST~1
EDIT /75 INDEX.DAT
More URLs from your internet history. Note, there are probably other mshist~x folders here so you can
repeat these steps for every occurence if you please.
13) By now, you'll probably want to type in this:
CD\WINDOWS
DELTREE/Y HISTORY
6)HOW MICROSOFT DOES IT
How does Microsoft make these folders/files invisible to DOS?
The only thing Microsoft had to do to make the folders/files invisible to a directory listing is to
set them +s[ystem]. That's it.
So how does Microsoft make these folders/files invisible to Windows Explorer?
The "desktop.ini" is a standard text file that can be added to any folder to customize certain aspects of
the folder's behavior. In these cases, Microsoft utilized the desktop.ini file to make these files
invisible. Invisible to Windows Explorer and even to the "Find: Files or Folders" utility. All that
Microsoft had to do was create a desktop.ini file with certain CLSID tags and the folders would disappear
like magic.
To show you exactly what's going on:
Found in the c:\windows\temporary internet files\desktop.ini and
the c:\windows\temporary internet files\content.ie5\desktop.ini is this text:
[.ShellClassInfo]
UICLSID={7BD29E00-76C1-11CF-9DD0-00A0C9034933}
Found in the c:\windows\history\desktop.ini and the c:\windows\history\history.ie5\desktop.ini is this text:
[.ShellClassInfo]
UICLSID={7BD29E00-76C1-11CF-9DD0-00A0C9034933}
CLSID={FF393560-C2A7-11CF-BFF4-444553540000}
The UICLSID line cloaks the folder in Windows Explorer. The CLSID line disables the "Find" utility
from searching through the folder.
To see for yourself, you can simply erase the desktop.ini files. You'll see that it will instantly give
Windows Explorer proper viewing functionality again, and the "Find" utility proper searching capabilities
again. Problem solved right? Actually, no. As it turns out, the desktop.ini files get reconstructed every
single time you restart your computer. Nice one, Slick.
Luckily there is a loophole which will keep Windows from hiding these folders. You can manually edit the
desktop.ini's and remove everything except for the "[.ShellClassInfo]" line. This will trick windows into
thinking they have still covered their tracks, and wininet won't think to reconstruct them.

STARTUP
-----------
Windows Prefetcher
******************
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management \ PrefetchParameters]
Under this key there is a setting called EnablePrefetcher, the default setting of which is 3. Increasing this number to 5 gives the prefetcher system more system resources to prefetch application data for faster load times. Depending on the number of boot processes you run on your computer, you may get benefits from settings up to 9. However, I do not have any substantive research data on settings above 5 so I cannot verify the benefits of a higher setting. This setting also may effect the loading times of your most frequently launched applications. This setting will not take effect until after you reboot your system.
Master File Table Zone Reservation
**********************************
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ FileSystem]
Under this key there is a setting called NtfsMftZoneReservation, the default setting of which is 1. The range of this value is from 1 to 4. The default setting reserves one-eighth of the volume for the MFT. A setting of 2 reserves one-quarter of the volume for the MFT. A setting of 3 for NtfsMftZoneReservation reserves three-eighths of the volume for the MFT and setting it to 4 reserves half of the volume for the MFT. Most users will never exceed one-quarter of the volume. I recommend a setting of 2 for most users. This allows for a "moderate number of files" commensurate with the number of small files included in most computer games and applications. Reboot after applying this tweak.
Optimize Boot Files
*******************
[HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Dfrg \ BootOptimizeFunction]
Under this key is a text value named Enable. A value of Y for this setting enables the boot files defragmenter. This setting defragments the boot files and may move the boot files to the beginning (fastest) part of the partition, but that last statement is unverified. Reboot after applying this tweak.
Optimizing Startup Programs [msconfig]
**************************************
MSConfig, similar to the application included in Win9x of the same name, allows the user to fine tune the applications that are launched at startup without forcing the user to delve deep into the registry. To disable some of the applications launched, load msconfig.exe from the run command line, and go to the Startup tab. From there, un-ticking the checkbox next to a startup item will stop it from launching. There are a few application that you will never want to disable (ctfmon comes to mind), but for the most part the best settings vary greatly from system to system.
As a good rule of thumb, though, it is unlikely that you will want to disable anything in the Windows directory (unless it's a third-party program that was incorrectly installed into the Windows directory), nor will you want to disable anything directly relating to your system hardware. The only exception to this is when you are dealing with software, which does not give you any added benefits (some OEM dealers load your system up with software you do not need). The nice part of msconfig is that it does not delete any of the settings, it simply disables them, and so you can go back and restart a startup application if you find that you need it. This optimization won't take effect until after a reboot.
Bootvis Application
*******************
The program was designed by Microsoft to enable Windows XP to cold boot in 30 seconds, return from hibernation in 20 seconds, and return from standby in 10 seconds. Bootvis has two extremely useful features. First, it can be used to optimize the boot process on your computer automatically. Second, it can be used to analyze the boot process for specific subsystems that are having difficulty loading. The first process specifically targets the prefetching subsystem, as well as the layout of boot files on the disk. When both of these systems are optimized, it can result in a significant reduction in the time it takes for the computer to boot.
Before attempting to use Bootvis to analyze or optimize the boot performance of your system, make sure that the task scheduler service has been enabled – the program requires the service to run properly. Also, close all open programs as well – using the software requires a reboot.
To use the software to optimize your system startup, first start with a full analysis of a fresh boot. Start Bootvis, go to the Tools menu, and select next boot. Set the Trace Repetition Settings to 2 repetitions, Start at 1, and Reboot automatically. Then set the trace into motion. The system will fully reboot twice, and then reopen bootvis and open the second trace file (should have _2 in the name). Analyze the graphs and make any changes that you think are necessary (this is a great tool for determining which startup programs you want to kill using msconfig). Once you have made your optimizations go to the Trace menu, and select the Optimize System item. This will cause the system to reboot and will then make some changes to the file structure on the hard drive (this includes a defragmentation of boot files and a shifting of their location to the fastest portion of the hard disk, as well as some other optimizations). After this is done, once again run a Trace analysis as above, except change the starting number to 3. Once the system has rebooted both times, compare the charts from the second trace to the charts for the fourth trace to show you the time improvement of the system's boot up.
The standard defragmenter included with Windows XP will not undo the boot optimizations performed by this application.

General Performance Tweaks
-----------------------------------
IRQ Priority Tweak
******************
[HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ PriorityControl]
You will need to create a new DWORD: IRQ#Priority (where # is the number of the IRQ you want to prioritize) and give it a setting of 1. This setting gives the requisite IRQ channel priority over the other IRQs on a software level. This can be extremely important for functions and hardware subsystems that need real-time access to other parts of the system. There are several different subsystems that might benefit from this tweak. Generally, I recommend giving either the System CMOS or the video card priority. The System CMOS generally has an IRQ setting of 8, and giving it priority enhances the I/O performance of the system. Giving priority to the video card can increase frame rates and make AGP more effective.
You can give several IRQs priority, but I am not entirely certain how the system interacts when several IRQs are given priority – it may cause random instabilities in the system, although it is more likely that there's a parsing system built into Windows XP to handle such an occurrence. Either way, I would not recommend it.
QoS tweak
*********
QoS (Quality of Service) is a networking subsystem which is supposed to insure that the network runs properly. The problem with the system is that it eats up 20% of the total bandwidth of any networking service on the computer (including your internet connection). If you are running XP Professional, you can disable the bandwidth quota reserved for the system using the Group Policy Editor [gpedit.msc].
You can run the group policy editor from the Run command line. To find the setting, expand "Local Computer Policy" and go to "Administrative Templates" under "Computer Configuration." Then find the "Network" branch and select "QoS Packet Scheduler." In the right hand box, double click on the "Limit Reservable Bandwidth." From within the Settings tab, enable the setting and then go into the "Bandwidth Limit %" and set it to 0%. The reason for this is that if you disable this setting, the computer defaults to 20%. This is true even when you aren't using QoS.
Free Idle Tasks Tweak
*********************
This tweak will free up processing time from any idle processes and allow it to be used by the foreground application. It is useful particularly if you are running a game or other 3D application. Create a new shortcut to "Rundll32.exe advapi32.dll,ProcessIdleTasks" and place it on your desktop. Double-click on it anytime you need all of your processing power, before opening the application.
Windows Indexing Services
Windows Indexing Services creates a searchable database that makes system searches for words and files progress much faster – however, it takes an enormous amount of hard drive space as well as a significant amount of extra CPU cycles to maintain the system. Most users will want to disable this service to release the resources for use by the system. To turn off indexing, open My Computer and right click on the drive on which you wish to disable the Indexing Service. Enter the drive's properties and under the general tab, untick the box for "Allow the Indexing Service to index this disk for fast file searching."
Priority Tweak
**************
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ PriorityControl]
This setting effectively runs each instance of an application in its own process for significantly faster application performance and greater stability. This is extremely useful for users with stability problems, as it can isolate specific instances of a program so as not to bring down the entire application. And, it is particularly useful for users of Internet Explorer, for if a rogue web page crashes your browser window, it does not bring the other browser windows down with it. It has a similar effect on any software package where multiple instances might be running at once, such as Microsoft Word. The only problem is that this takes up significantly more memory, because such instances of a program cannot share information that is in active memory (many DLLs and such will have to be loaded into memory multiple times). Because of this, it is not recommended for anyone with less than 512 MB of RAM, unless they are running beta software (or have some other reason for needing the added stability).
There are two parts to this tweak. First is to optimize XP's priority control for the processes. Browse to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ PriorityControl and set the "Win32PrioritySeparation" DWORD to 38. Next, go into My Computer and under Tools, open the Folder Options menu. Select the View tab and check the "Launch folder windows in separate process" box. This setting actually forces each window into its own memory tread and gives it a separate process priority.
Powertweak application
**********************
xxx.powertweak.com
Powertweak is an application, which acts much like a driver for our chipsets. It optimizes the communication between the chipset and the CPU, and unlocks several "hidden" features of the chipset that can increase the speed of the system. Specifically, it tweaks the internal registers of the chipset and processor that the BIOS does not for better communication performance between subsystems. Supported CPUs and chipsets can see a significant increase in I/O bandwidth, increasing the speed of the entire system. Currently the application supports most popular CPUs and chipsets, although you will need to check the website for your specific processor/chipset combo – the programmer is working on integrating even more chipsets and CPUs into the software.
Offload Network Task Processing onto the Network Card
*****************************************************
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters]
Many newer network cards have the ability of taking some of the network processing load off of the processor and performing it right on the card (much like Hardware T&L on most new video cards). This can significantly lower the CPU processes needed to maintain a network connection, freeing up that processor time for other tasks. This does not work on all cards, and it can cause network connectivity problems on systems where the service is enabled but unsupported, so please check with your NIC manufacturer prior to enabling this tweak. Find the DWORD "DisableTaskOffload" and set the value to 0 (the default value is 1). If the key is not already available, create it.
Force XP to Unload DLLs
***********************
[HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer]
"AlwaysUnloadDLL"=dword:00000001
XP has a bad habit of keeping dynamic link libraries that are no longer in use resident in memory. Not only do the DLLs use up precious memory space, but they also tend to cause stability problems in some systems. To force XP to unload any DLLs in memory when the application that called them is no longer in memory, browse to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer and find the DWORD "AlwaysUnloadDLL". You may need to create this key. Set the value to 1 to force the operating system to unload DLLs.
Give 16-bit apps their own separate processes
*********************************************
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ WOW]
"DefaultSeparateVDM"="Yes"
By default, Windows XP will only open one 16-bit process and cram all 16-bit apps running on the system at a given time into that process. This simulates how MS-DOS based systems viewed systems and is necessary for some older applications that run together and share resources. However, most 16-bit applications work perfectly well by themselves and would benefit from the added performance and stability of their own dedicated resources. To force Windows XP to give each 16-bit application it's own resources, browse to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ WOW and find the String "DefaultSeparateVDM". If it is not there, you may need to create it. Set the value of this to Yes to give each 16-bit application its own process, and No to have the 16-bit application all run in the same memory space.
Disable User Tracking
*********************
[HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer]
"NoInstrumentation"=dword:00000001
The user tracking system built into Windows XP is useless to 99% of users (there are very few uses for the information collected other than for a very nosy system admin), and it uses up precious resources to boot, so it makes sense to disable this "feature" of Windows XP. To do so, browse to HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer and find the DWORD "NoInstrumentation". You may need to create this key if it is not there. The default setting is 0, but setting it to 1 will disable most of the user tracking features of the system.
Thumbnail Cache
***************
[HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced]
"DisableThumbnailCache"=dword:00000001
Windows XP has a neat feature for graphic and video files that creates a "thumbnail" of the image or first frame of the video and makes it into an oversized icon for the file. There are two ways that Explorer can do this, it can create them fresh each time you access the folder or it can load them from a thumbnail cache. The thumbnail caches on systems with a large number of image and video files can become staggeringly large. To disable the Thumbnail Cache, browse to HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced and find the DWORD "DisableThumbnailCache". You may need to create this key. A setting of 1 is recommended for systems where the number of graphic and video files is large, and a setting of 0 is recommended for systems not concerned about hard drive space, as loading the files from the cache is significantly quicker than creating them from scratch each time a folder is accessed.
Your Own Home Server - Introduction
An Introduction
In this tutorial you will learn how to step up your own server. This server will be comprised of Apache 1.3.5, PHP 4.2.0, and MySQL 3.23.49. This tutorial will address the basic setup of a server on your own computer. This means the removal of hassles of dealing with the company that is running a remote web server. It will be easy to modify. You can add any thing you want to it, be it CGI/Perl, Zope, Roxen, etc, all by your self. You will have unlimited disk space, well at least as big as your hard drive is =) Now that you know the advantages, it is time that I tell you what i used, and what you will need.
What I used
* Windows 2000 - NOTE that if you are using 2k you WILL NEED Administrative Privileges. If you don't then get them somehow =) If you are on 95, 98, NT, XP, ME, I
* Apache 1.3.6 - I tried to use 2.0 but I could not get it work. I also feel that 1.3.6 is tried and true, so why mess with greatness.
* Mysql 3.23.49 - The newest version of MySQL when I set up my server. MySQL also the is the best PHP supported Database, and well love PHP don't we.
* PHP 4.2.1 - The latest and greatest PHP release. -nt
What you will need
* Apache 2 - Link: h**p://www.apache.org/dist/
* Mysql 3.23.49 - Link: h**p://www.mysql.com/downloads/mysql-3.23.html
* PHP 4.2.0 - Link: h**p://www.php.net/downloads.php
* Windows - This tutorial is ONLY written for new versions of Windows.
Once you have downloaded all the programs you are ready to continue.
1. Installing Apache
Installing Apache
The first step is to download Apache for Windows. Before you install it make sure that any other server software is removed. Remove it all via the control panel.On
Once you have clicked on the executable, a screen should com up that looks like this. Go ahead and click on next

You really don't need to read this, but if you want you can. Read it if you want feel informed. When you are ready click on next.

Here is where the actual setup of Apache begins. For Network Domain put in localhost as for Server Name You want these both to be localhost because the server is running locally, on your computer. It doesn't matter what is in email field, just put in yours. No one will no it because it's just you.

For the sake of this tutorial it is better to just leave it as it is because, later in the tutorial I will show you how to start the server with one click of the mouse, and for the sake of ease, it will be easier for you to follow along. You can change it if you want, but you will have to realize where to substitute it. For me the root drive is E: but for you will probably be C:

Once you have all the jazz set up, it is time to install the server. If you are on w2k or XP be sure that you have Administrative permissions or you will get an error about half way through the install saving cannot access msvrt32.dll or something. If you get that error run it again when you have admin privileges. Once you are ready click on install.
user posted image
If all went well you just see a screen similar to this. Now it is time to test the install of apache. Click on Start > Program Files > Apache HTTP Server and look for start Start Apache in Console. Click it. Once it says Apache XXXXX running, press Windows Key + R and type -http://localhost/. If the install works you should see a page saying that it works. If all is set and done, continue to the next step.

For this information, we will want the simple standard install. Chances are you if you are reading this tutorial, you will probably not even want to talk about advanced =)

This is the mail setup, just enter localhost, and me@localhost.com. These are not important, because you, the admin, are the only person that will use the server, and you will be the one handling errors.

We are going to want this install to work is Apache, so click on Apache, and move on.

After the install is done you should get something that says you will have to manually configure apache to use php. Assuming you have a working Apache server installed, make sure that it is not running. Navigate to C:\Program Files\Apache Group\Apache\conf\ open the httpd.conf file. Note that you can also get to the http.conf from the start menu. Start > Program File > Apache HTTP Server > Configure Apache Server > Edit the Apache httpd.conf Configuration File and the window will open up in notepad. Now hit Ctrl + End if you see something like what follows, you can skip this step. If you do not see that code, copy it. This code will only work if you used the default install folder when you installed php. If you did, copy that code and paste it into the end of the file. Select the code to right, and hit crtl + c , then go into the httpd.conf file and hit ctrl + v and save the file.
ScriptAlias /php/ "c:/php/"
AddType application/x-httpd-php .php .phtml
Action application/x-httpd-php "/php/php.exe"
Now that we have php installed, it is time to test it. Open up notepad and type the code to the right. Save it as phpinfo.php. Remember to set it as all files in the drop down menu, or the file will be a text file. Save in the Directory: C:\Program Files\Apache Group\Apache\htdocs. htdocs is the directory where all the files go. You can create endless dir's and browse them. For Example E:\Program Files\Apache Group\Apache\htdocs\mydir\myfile.php could be accessed as http://localhost/mydir/myfile.php. Once you have that file saved. You will need to start the Server. Click: Start > Program File > Apache HTTP Server >; and look for something like Start Apache in Console. After you have found it, launch it. You should get a window saying that Apache is running. Now go to Start > Run > and type in -http://localhost/phpinfo.php. If you don't see anything, php is not installed correctly. If php is installed correctly, you will see a few large tables, displaying php's configuration. Now Your are 1/2 done!
______________________________________________________________________
3. Installing MySQL
Once you have clicked on the executable, a screen should com up that looks like this. Go ahead and click on next.
user posted image
Of course you plan to abide be the license agreement, so click on I accept.... and click on next.
Just like before you should leave the default dir alone, so you will be able to follow along with me when I show you how to start and stop all the aspects of the server.
Stay with the typical installation. Just like before, if you don't have admin privileges, the install will be faulty. After you click next, the install will begin. After the install has finished, move on to the next step.
Now you have to set up the root account. The root account is the absolute admin of the system, the highest possible. Click on Start > Run and type cmd to open up the command prompt. You are going to have to navigate to where MySQL is installed. Type C: > Enter > cd mysql > Enter > cd bin > Enter. Now you have to tell setup the root settings. Type mysqladmin -uroot password InsertYourPasswordHere then hit enter.
To see an image of the screen, -h**p://www.webmasterstop.com/tutorials/images/doscreen1.gif
What is the point of having a database if you can't easily administer it! That is where phpMyAdmin comes into play. phpMyAdmin is a free piece of software written in php that makes the administration of a mysql or many other types of databases easy. You will want to download (h**p://prdownloads.sourceforge.net/phpmyadmin/phpMyAdmin-2.2.6-php.zip?downloadrelease_id=85832)the latest version. Save it in the htdocs folder. Once it is done downloading it, right click on it and select Extract > To Here. When it is done you should end up with a directory in the htdocs folder called phpMyAdmin-2.2.6 To make it easier to access, rename it to phpMyAdmin. After you have renamed it, click on it and look for a file called config.inc Open it. This is where you set the configuration of phpMyAdmin. When you open it up, it should look similar to the image to your side. On yours there should be a few things missing. The $cfgPmaAbsoulteUrl and $cfgservers[$i]['password']. You will need to fill those in between the quotes. for the $cfgPmaAbsoulteUrl enter -http://localhost/phpMyAdmin/ if you followed my instructions to the letter. If you did not rename it or extracted to a different directory, put that in there. For the $cfgservers[$i]['password'] enter the password you entered when you were setting MySQL in the set above. You can refer to the image for help. After you have put the right things in save the file.
To see an image of the screen, -h**p://www.webmasterstop.com/tutorials/images/phpmyadminscreen1.gif
Now we want to test the install of mysql, php, phpmyadmin, and apache all at once. Start apache in console like we did before. Now, you are going to need to start mysql. For myself I made a file that would start mysql for me. Open notepad and type: start c:\mysql\bin\mysqld-nt.exe --standalone and save that as Start MySQL.bat. Once you have saved it, click it. A window should open and then close. Mysql is now running on your computer. After mysql and apache are started go to run again and type -http://localhost/phpMyAdmin/index.php and if everything is installed correctly phpmyadmin should so up. You are almost done! Now we have the easy part =)
4. Finishing it all up
Wow! We mad it through the whole process. Now we want to simplify the whole process of controlling the server. I made a toolbar with all the things I needed. I made a new folder on my desktop and called it Server Folder and put all the stuff there. I made a new shortcut and gave it a value of -http://localhost/ made a shortcut to the PHP Documentation page. Another shortcut to my php editor, which is now unavailable. The phpMyAdmin shortcut is set to -http://localhost/phpMyAdmin/index.php. I made another shortcut htdocs. I moved the Start Apache in Console program that was in the start menu folder and moved it to the server folder. You can take the Start Mysql file you made in the last page and move it to the new folder. After you have put all the desired things into that folder, right click on a blank space in stat menu task bar (where the program boxes lie) and select Toolbars > New Toolbar and navigate to the folder. Voila!
Now all you have to do is click Start Apache in Console , Start Mysql, and Lauch browser biggrin.gif
Here You Are Guys
10 reasons why PCs crash U must Know
Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."
You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?
1 Hardware conflict
The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.
For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.
If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:
* Start-Settings-Control Panel-System-Device Manager.
Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.
Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.
Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).
When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.
To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.
2 Bad Ram
Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.
But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.
One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.
Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.
EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.
3 BIOS settings
Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.
Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.
A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.
Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).
4 Hard disk drives
After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to
* Start-Programs-Accessories-System Tools-Disk Defragmenter
This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.
The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).
Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. This can be adjusted by going to
* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.
Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.
Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to
* Start-Programs-Accessories-System Tools-ScanDisk
Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.
5 Fatal OE exceptions and VXD errors
Fatal OE exception errors and VXD errors are often caused by video card problems.
These can often be resolved easily by reducing the resolution of the video display. Go to
* Start-Settings-Control Panel-Display-Settings
Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For most desktops, high colour 16-bit depth is adequate.
If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. Go to
* Start-Settings-Control Panel-System-Device Manager
Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.
If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse.
The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.
Another useful way to resolve video problems is to go to
* Start-Settings-Control Panel-System-Performance-Graphics
Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).
Look up your video card's manufacturer on the internet and search for the most recent drivers for it.
6 Viruses
Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to
* Start-Settings-Control Panel-Add/Remove Programs
Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.
A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.
An excellent antivirus programme is McAfee VirusScan by Network Associates ( www.nai.com). Another is Norton AntiVirus 2000, made by Symantec ( www.symantec.com).
7 Printers
The action of sending a document to print creates a bigger file, often called a postscript file.
Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer's performance.
If the printer is trying to print unusual characters, these might not be recognised, and can crash the computer. Sometimes printers will not recover from a crash because of confusion in the buffer. A good way to clear the buffer is to unplug the printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer's default settings and you may be able to carry on.
8 Software
A common cause of computer crash is faulty or badly-installed software. Often the problem can be cured by uninstalling the software and then reinstalling it. Use Norton Uninstall or Uninstall Shield to remove an application from your system properly. This will also remove references to the programme in the System Registry and leaves the way clear for a completely fresh copy.
The System Registry can be corrupted by old references to obsolete software that you thought was uninstalled.

Often a Windows problem can be resolved by entering Safe Mode. This can be done during start-up. When you see the message "Starting Windows" press F4. This should take you into Safe Mode.
Safe Mode loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading properly.
Sometimes installing Windows is difficult because of unsuitable BIOS settings. If you keep getting SUWIN error messages (Windows setup) during the Windows installation, then try entering the BIOS and disabling the CPU internal cache. Try to disable the Level 2 (L2) cache if that doesn't work.
Remember to restore all the BIOS settings back to their former settings following installation.
9 Overheating
Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.
One remedy is to get a bigger better fan and install it on top of the CPU. Specialist cooling fans/heatsinks are available from www.computernerd.com or www.coolit.com
CPU problems can often be fixed by disabling the CPU internal cache in the BIOS. This will make the machine run more slowly, but it should also be more stable.
10 Power supply problems
With all the new construction going on around the country the steady supply of electricity has become disrupted. A power surge or spike can crash a computer as easily as a power cut.
If this has become a nuisance for you then consider buying a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.
It is a good investment if your data are critical, because a power cut will cause any unsaved data to be lost.
BandWidth Explained
Most hosting companies offer a variety of bandwidth options in their plans. So exactly what is bandwidth as it relates to web hosting? Put simply, bandwidth is the amount of traffic that is allowed to occur between your web site and the rest of the internet. The amount of bandwidth a hosting company can provide is determined by their network connections, both internal to their data center and external to the public internet.
Network Connectivity
The internet, in the most simplest of terms, is a group of millions of computers connected by networks. These connections within the internet can be large or small depending upon the cabling and equipment that is used at a particular internet location. It is the size of each network connection that determines how much bandwidth is available. For example, if you use a DSL connection to connect to the internet, you have 1.54 Mega bits (Mb) of bandwidth. Bandwidth therefore is measured in bits (a single 0 or 1). Bits are grouped in bytes which form words, text, and other information that is transferred between your computer and the internet.
If you have a DSL connection to the internet, you have dedicated bandwidth between your computer and your internet provider. But your internet provider may have thousands of DSL connections to their location. All of these connection aggregate at your internet provider who then has their own dedicated connection to the internet (or multiple connections) which is much larger than your single connection. They must have enough bandwidth to serve your computing needs as well as all of their other customers. So while you have a 1.54Mb connection to your internet provider, your internet provider may have a 255Mb connection to the internet so it can accommodate your needs and up to 166 other users (255/1.54).
Traffic
A very simple analogy to use to understand bandwidth and traffic is to think of highways and cars. Bandwidth is the number of lanes on the highway and traffic is the number of cars on the highway. If you are the only car on a highway, you can travel very quickly. If you are stuck in the middle of rush hour, you may travel very slowly since all of the lanes are being used up.
Traffic is simply the number of bits that are transferred on network connections. It is easiest to understand traffic using examples. One Gigabyte is 2 to the 30th power (1,073,741,824) bytes. One gigabyte is equal to 1,024 megabytes. To put this in perspective, it takes one byte to store one character. Imagine 100 file cabinets in a building, each of these cabinets holds 1000 folders. Each folder has 100 papers. Each paper contains 100 characters - A GB is all the characters in the building. An MP3 song is about 4MB, the same song in wav format is about 40MB, a full length movie can be 800MB to 1000MB (1000MB = 1GB).
If you were to transfer this MP3 song from a web site to your computer, you would create 4MB of traffic between the web site you are downloading from and your computer. Depending upon the network connection between the web site and the internet, the transfer may occur very quickly, or it could take time if other people are also downloading files at the same time. If, for example, the web site you download from has a 10MB connection to the internet, and you are the only person accessing that web site to download your MP3, your 4MB file will be the only traffic on that web site. However, if three people are all downloading that same MP at the same time, 12MB (3 x 4MB) of traffic has been created. Because in this example, the host only has 10MB of bandwidth, someone will have to wait. The network equipment at the hosting company will cycle through each person downloading the file and transfer a small portion at a time so each person's file transfer can take place, but the transfer for everyone downloading the file will be slower. If 100 people all came to the site and downloaded the MP3 at the same time, the transfers would be extremely slow. If the host wanted to decrease the time it took to download files simultaneously, it could increase the bandwidth of their internet connection (at a cost due to upgrading equipment).
Hosting Bandwidth
In the example above, we discussed traffic in terms of downloading an MP3 file. However, each time you visit a web site, you are creating traffic, because in order to view that web page on your computer, the web page is first downloaded to your computer (between the web site and you) which is then displayed using your browser software (Internet Explorer, Netscape, etc.) . The page itself is simply a file that creates traffic just like the MP3 file in the example above (however, a web page is usually much smaller than a music file).
A web page may be very small or large depending upon the amount of text and the number and quality of images integrated within the web page. For example, the home page for CNN.com is about 200KB (200 Kilobytes = 200,000 bytes = 1,600,000 bits). This is typically large for a web page. In comparison, Yahoo's home page is about 70KB.
How Much Bandwidth Is Enough?
It depends (don't you hate that answer). But in truth, it does. Since bandwidth is a significant determinant of hosting plan prices, you should take time to determine just how much is right for you. Almost all hosting plans have bandwidth requirements measured in months, so you need to estimate the amount of bandwidth that will be required by your site on a monthly basis
If you do not intend to provide file download capability from your site, the formula for calculating bandwidth is fairly straightforward:
Average Daily Visitors x Average Page Views x Average Page Size x 31 x Fudge Factor
If you intend to allow people to download files from your site, your bandwidth calculation should be:
[(Average Daily Visitors x Average Page Views x Average Page Size) +
(Average Daily File Downloads x Average File Size)] x 31 x Fudge Factor
Let us examine each item in the formula:
Average Daily Visitors - The number of people you expect to visit your site, on average, each day. Depending upon how you market your site, this number could be from 1 to 1,000,000.
Average Page Views - On average, the number of web pages you expect a person to view. If you have 50 web pages in your web site, an average person may only view 5 of those pages each time they visit.
Average Page Size - The average size of your web pages, in Kilobytes (KB). If you have already designed your site, you can calculate this directly.
Average Daily File Downloads - The number of downloads you expect to occur on your site. This is a function of the numbers of visitors and how many times a visitor downloads a file, on average, each day.
Average File Size - Average file size of files that are downloadable from your site. Similar to your web pages, if you already know which files can be downloaded, you can calculate this directly.
Fudge Factor - A number greater than 1. Using 1.5 would be safe, which assumes that your estimate is off by 50%. However, if you were very unsure, you could use 2 or 3 to ensure that your bandwidth requirements are more than met.
Usually, hosting plans offer bandwidth in terms of Gigabytes (GB) per month. This is why our formula takes daily averages and multiplies them by 31.
Summary
Most personal or small business sites will not need more than 1GB of bandwidth per month. If you have a web site that is composed of static web pages and you expect little traffic to your site on a daily basis, go with a low bandwidth plan. If you go over the amount of bandwidth allocated in your plan, your hosting company could charge you over usage fees, so if you think the traffic to your site will be significant, you may want to go through the calculations above to estimate the amount of bandwidth required in a hosting plan.
When you receive an email, you receive more than just the message. The email comes with headers that carry important information that can tell where the email was sent from and possibly who sent it.
