The BIOSÂ and UEFI is another essential system program that is responsible for the system booting process.
The computer system becomes available to the user to perform any task when the operating system is fully loaded and operational.
And therefore , when the computer is switched on , the CPU’s first task is to load the operating system into the main memory RAM. This process is called system booting.
The CPU initiates the system booting process with the help of another system program called the BIOS. The BIOS stands for Basic Input Output System.
