| How to add USB ports to your PC |
| Tuesday, 29 May 2007 |
Any PC that you buy today comes with one or more Universal Serial Bus(USB) connectors on the back. These USB connectors let you attach everything from mice to printers to your computer quickly and easily. The operating system supports USB as well, so the installation of the device drivers is quick and easy, too. Compared to other ways of connecting devices to your computer (including parallel ports, serial ports and special cards that you install inside the computer's case), USB devices are incredibly simple!
A few devices which work on USB are:Printers,mice,webcams,modems,datadrives,scanners,joysticks,speakers etc.
The above photo shows a connection that goes into the USB port.
Connecting a USB device to a computer is simple -- you find the USB connector on the back of your machine and plug the USB connector into it.
The empty slot shown above is how a typical USB port looks like.
Most computers that you buy today come with one or two USB sockets. With so many USB devices on the market today, you easily run out of sockets very quickly. For example, you may have a USB printer, a USB scanner, a USB Webcam and a USB network connection. And your computer has only one USB connector on it, so the obvious question is, "How do you hook up all the devices?"
The easy solution to the problem is to buy an inexpensive USB hub. The USB standard supports up to 127 devices, and USB hubs are a part of the standard.
The above is a powered hub.
A hub typically has four new ports, but may have many more. You plug the hub into your computer, and then plug your devices (or other hubs) into the hub. By chaining hubs together, you can build up dozens of available USB ports on a single computer.
Hubs can be powered or unpowered.The USB standard allows for devices to draw their power from their USB connection. Obviously, a high-power device like a printer or scanner will have its own power supply, but low-power devices like mice and digital cameras get their power from the bus in order to simplify them. The power (up to 500 milliamps at 5 volts) comes from the computer. If you have lots of self-powered devices (like printers and scanners), then your hub does not need to be powered -- none of the devices connecting to the hub needs additional power, so the computer can handle it. If you have lots of unpowered devices like mice and cameras, you probably need a powered hub.Labels: hardware, tips |

| Hack Your BIOS |
| Saturday, 26 May 2007 |
BIOS is an acronym for Basic Input Output System.BIOS refers to the firmware code run on PC when first powered on. The primary function of the BIOS is to prepare the machine so other software programs stored on various media (such as hard drives, floppies, and CDs) can load, execute, and assume control of the PC. This process is known as booting up.
BIOS can also said to be a coded program embedded on a chip that recognizes and controls various devices that make up the PC.
To enter the BIOS program, hit the "Delete" key before your computer boots up.If successful,you will be taken to a menu which would be similar to as one given below.
Sometimes ,in order to prevent unauthorised access,the BIOS menu is password protected.(See the righthand side column in the above photo)When a password is set,the BIOS settings can only be accessed by authorised access.
But what if you lose this password and want to change some BIOS settings?No need to worry,this password can easily be hacked.
All BIOS settings are stored in the memory even after the computer is switched off.This is done by a small battery which is placed on your motherboard.
 Since the BIOS password is a part of BIOS setting,it is stored in memory by this battery.
To hack the BIOS password-->
1.Switch off your PC.
2.Open your computer cabinet.
3.Locate the battery on motherboard and carefully remove it.(ALL BIOS SETTINGS ARE LOST)
4.Re-insert the battery.(ALL BIOS settings are reset)
5.Switch on the PC.
When you try to access the BIOS menu,you won't be prompted for a password.Labels: hack, tips, tricks |
