What is the full form of BIOS?

The full form of BIOS is the Basic Input Output System.

The Basic Input Output System is the full name of the BIOS. A computer’s BIOS is a piece of integrated software. It is the first application that the computer system runs when we turn it on. This application is typically located on the motherboard in Read-Only Memory (ROM). In contemporary computers, flash memory is used to store the contents of the BIOS.

A computer would be difficult to start without BIOS since it loads the hard disc drivers and important operating system components like GPT, FAT, MBR, etc. into the storage to enable the operating system to start loading itself. System BIOS is also known as PS BIOS and ROM BIOS.

The activities carried out by BIOS are listed below:

Power management and register initialization are handled by BIOS.
It does a device driver check, loads the drivers into RAM, and loads interrupt handlers.
System settings are displayed via it.
The devices that can boot are listed in BIOS.
The BIOS starts the Bootstrap process.
