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-4: -ROM is used for holding up the startup instructions in the computer. This option is correct as it is the permanent memory which is also called the firmware. The instructions are stored when turned on.

Detailed explanation-5: -The main set of instructions stored on ROM is the BIOS. BIOS stands for Basic Input/Output System. The BIOS provides instructions for the processor allowing it to interact with the Hard Disk and therefore boor the Operating System. Without the BIOS, the Operating System could not be booted.
