Detailed explanation-1: -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).
Detailed explanation-2: -A computer’s basic input/output system (BIOS) is a program that’s stored in nonvolatile memory such as read-only memory (ROM) or flash memory, making it firmware. The BIOS (sometimes called ROM BIOS) is always the first program that executes when a computer is powered up.
Detailed explanation-3: -Read-Only Memory (ROM) is storage technology that permanently stores data in a chip built into computers and other electronic devices. ROM includes the most basic programming needed to start a computer, often referred to as Basic Input/Output System (BIOS).
Detailed explanation-4: -Originally, BIOS firmware was stored in a ROM chip on the PC motherboard. In later computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard.
