MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -BIOS instructs the computer on how to perform basic functions like booting and keyboard control; it is also used to identify and configure the hardware in a computer such as the hard drive, CPU, memory, and related equipment.

Detailed explanation-2: -BIOS. BIOS stands for Basic Input Output System. The BIOS is stored in the ROM. It contains all the basic code for controlling your computer hardware (such as keyboards, mice, monitors and hard drives).
