Detailed explanation-1: -Hence when a computer is switched on, the BIOS is loaded from ROM. Random-access memory is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. It is a computer’s short-term memory.

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: -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.

Detailed explanation-4: -BIOS uses Flash memory, a type of ROM. The BIOS software has a number of different roles, but its most important role is to load the operating system.

Detailed explanation-5: -The boot ROM is a type of ROM that is used for booting a computer system. There are two types: a mask boot ROM that cannot be changed afterwards and a boot EEPROM, which can contain an UEFI implementation.
