Detailed explanation-1: -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-2: -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.
Detailed explanation-3: -It’s the same thing. BIOS is alternately called ROM BIOS, PC BIOS, and System BIOS. BIOS is the first software that runs when you power on your system, performing an initial pack of diagnostic tests (POST, or Power On Self-Test) to see if there are any issues with the hardware.
Detailed explanation-4: -Traditionally, the BIOS (the computer boot up instruction set) was always stored in ROM because it is non-volatile. However, flash memory (which is also non-volatile, but not read-only) is now often used for the BIOS so that changes to the instructions can be made.
