Detailed explanation-1: -BIOS identifies, configures, tests and connects computer hardware to the OS immediately after a computer is turned on. The combination of these steps is called the boot process. These tasks are each carried out by BIOS’ four main functions: Power-on self-test (POST).
Detailed explanation-2: -All modern computer motherboards contain BIOS software. BIOS access and configuration are independent of any operating system because the BIOS is part of the motherboard hardware.
Detailed explanation-3: -So, to recap, BIOS is firmware (in other words, software embedded in a piece of hardware) stored on a ROM chip that lets you access and set up your system at its most basic level.
Detailed explanation-4: -The BIOS includes instructions on how to load basic computer hardware. The BIOS also includes a test referred to as a POST (Power On Self Test) which will ensure that the computer meets requirements to boot up properly.
