BIOS

BIOS intro:

BIOS refers to Basic Input Output System.

This is a must for any computer and is given by default on motherboards when every you purchase one. This gives the basic necessary controls which are used to modify how the hardware is working, it helps in controlling the power supply, apply superior passwords to systems, and to modify the boot orders.

BIOS is important as it detects the hardware of the systems, not all but all the major ones that like the ones that are present onboard.

How to access the bios?

You can assess the BIOS controls by using 'DEL' key on your keyboard. In most cases it is the del key, else it is 'F10' key and may change on systems. Example: F1, F11, F12 etc.

How bios works?

BIOS works by storing the settings on a small chip that is onboard. The chips stores the data that is modified by using a small Battery. If the battery fails to supply enough power, or if it is dead, the changes made in the BIOS are lost every time the system is switched off.
