Question
In computer fundamentals, what is the primary purpose of
the BIOS in a computer system?Solution
The BIOS (Basic Input/Output System) is firmware stored on a chip in the motherboard. Its primary purpose is to initialize and test the system hardware components and load the operating system from a storage device during the boot process. The BIOS ensures that the computer is in a proper state before passing control to the operating system's bootloader. Why Other Options are Wrong: a) The BIOS does not control hardware access directly; it performs initial hardware checks and setups. c) Applications run on the operating system, not the BIOS. d) Managing network connections is the job of the operating system and networking software. e) Real-time processing is handled by the operating system or application software designed for real-time use.
