BIOS stands for Basic Input/Output System. It is a firmware program that is stored on a small memory chip on the motherboard of a computer. The BIOS is responsible for booting the computer and providing an interface between the operating system and the hardware.
When you turn on a computer, the BIOS performs a power-on self-test (POST) to check that the hardware is functioning properly. If the POST is successful, the BIOS loads the bootloader, which then loads the operating system.
The BIOS also provides a configuration utility that allows you to change certain settings on your computer, such as the boot order, time and date, and hardware settings. You can access the BIOS configuration utility by pressing a specific key (such as “F2” or “Delete”) during the boot process.
I hope this helps! Let me know if you have any other questions.
