Bandwidth Explained!

This is well written explanation about bandwidth, very useful info.



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.

How To Rename Extensions With Ease, with a Renamer.bat file!

You all downloaded some game or app once that was 50 parts big, and you had to rename them all from .bmp to .rar to extract them.

You can easily create a batch file that does that for you.


Open Notepad

fill in the notepad:

CODE

ren *.bmp *.rar


Ofcourse, you have to edit these two extensions to fit the files you want to convert. Save this file as renamer.bat and run it in the directory where you want to rename your downloads.

How To Convert File System, fat - fat32 to ntfs

How To Convert File System, fat - fat32 to ntfs

open a dos prompt and give the command

convert d: /fs:ntfs

this command would convert your d: drive to ntfs.

if the system cannot lock the drive, you will be prompted to convert it during next reboot.

Normally you should select yes.

Conversion from fat/fat32 to ntfs is non-destructive, your data on the drive will NOT be lost.

Be aware that converting to ntfs will make that partition of your
drive unreadable under dos unless you have ntfs utilites to do so.

How To Access Your Folders From Your Taskbar

This is an easy way to get to the folders on your system without having to open a Windows Explorer Window every time you want to access files. I find it very useful to have this feature as it allows me to access my Folders and Drives immediately and saves me a lot of time.

This works in Windows XP:

1. Right Click an empty spot on your Taskbar (Between your Start Button and your System Tray).
2. Click Toolbars.
3. Click New Toolbar.
4. A Small Window will Open that allows you to pick the folder you wish to make a Toolbar. If you want to access your Desktop Without having to minimize all your windows. Just Pick Desktop. If you want to access ONLY your My Documents Folder, Select that. Any folder will work for this.
5. Click OK.
The New Tool bar will appear at the bottom of your screen next to your System Tray.

If you find this to be not useful, Repeat Steps 1 and 2 and then check click the Toolbar you created that has a check mark next to it. And it will disappear.

Hard Drive Go Bad

Hard drive gone bad

The most common problems originate
from corruption of the master boot record, FAT, or directory.
Those are soft problems which can usually be taken care of
with a combination of tools like Fdisk /mbr to refresh the
master boot record followed by a reboot and Norton disk doctor
or Spinneret.

The most common hardware problems are a bad controller, a bad
drive motor, or a bad head mechanism.

Best Keyboard Shortcuts

Getting used to using your keyboard exclusively and leaving your mouse behind will make you much more efficient at performing any task on any Windows system. I use the following keyboard shortcuts every day:

Windows key + R = Run menu

This is usually followed by:

iexplore + "web address" = Internet Explorer
compmgmt.msc = Computer Management
dhcpmgmt.msc = DHCP Management
dnsmgmt.msc = DNS Management
services.msc = Services
eventvwr = Event Viewer
dsa.msc = Active Directory Users and Computers
dssite.msc = Active Directory Sites and Services
Windows key + E = Explorer

BIOS Beep Codes

When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected.
Because there are many brands of BIOS, there are no standard beep codes for every BIOS.

How to Speed up slow Computer

How To Speed Up A Slow Computer

First off in the bottom right hand corner of your computer if you see alot of icons start up there when you first start your computer then this is for you if you dont know already how to get rid of em.

Press your Start Button (bottom left) and go to "run"

now type in: msconfig

now you will get a box that pops up and will tell you bunch of stuff don't mess with anything else other than what I tell you otherwise you could do something really bad (possible) go to your "startup" tab on the top right of the screen where it usually is and click it.

Now you will have a closed in box with bunch of file names n addresses and more boxes with checks in them. Now if your like me you don't want anything starting up when you start you computer up or while your even doing anything cause it slows you down. Now unless your like me right now 1 have 1 thing starting up when my computer starts up and that's my setting for my overclocked vid card. But other than that uncheck every box and then hit apply and ok. Then window you were us in will now close and ask you if you want to restart or wait till later to restart.

Either way when you shut it off and then turn it back on the settings will kick in 

What is Virus

A program or piece of codethat is loaded onto your computer without your knowledge and runs against your wishes. Viruses can also replicate themselves. All computer viruses are manmade. A simple virus that can make a copyof itself over and over again is relatively easy to produce. Even such a simple virus is dangerous because it will quickly use all available memoryand bring the system to a halt. An even more dangerous type of virus is one capable of transmitting itself across networks and bypassing security systems.

Since 1987, when a virus infected ARPANET, a large network used by the Defense Department and many universities, many antivirus programs have become available. These programs periodically check your computer system for the best-known types of viruses.

Some people distinguish between general viruses and worms. A worm is a special type of virus that can replicate itself and use memory, but cannot attach itself to other programs.
