Answer 1

ROM is a special kind of memory which stores the instructions which the computer uses when it 'boots up' - the BIOS (basic input output system). ... ROM is a type of memory that retains its data even without power, so even when the computer is switched off, it will not lose the data which is saved onto it.ROM stands for read-only memory.
