What is BIOS?
BIOS is known as basic input/output system (BIOS).
The BIOS software is built into the computer through a ROM (Read Only Memory), and is the first code run by a computer when powered ON. When the computer starts up, the first job for the BIOS is the power-on self-test, which initializes and identifies system devices such as the CPU, RAM, video display card, keyboard and mouse, hard disk drive, optical disc drive and other hardware.
The BIOS then locates Operating System(OS) installed on a hard disk or a CD/DVD, and loads and executes that software, giving it control of the computer. This process is known as booting, or booting up, which is short for bootstrapping.
Steps to identify the BIOS your computer is using
1. Switch ON your computer. You may see a BIOS start up screen.

The BIOS logo will be displayed on the top. You can determine the BIOS you are using by seeing the logo in the BIOS start screen.
Some BIOS will not show the above BIOS instead will show a splash screen. It may also ask to press a particular key (Tab Key) to show the BIOS screen. When you press that key you can be see the BIOS screen as shown above.
2. Another way to find out the BIOS, is to open the system and directly finding out the BIOS chip. The manufacturer label will be over the BIOS chip.
