Why is ROM necessary?

Why does a computer need ROM and RAM?

RAM is volatile, requiring power to store data. ROM is often used to store the BIOS program on a computer motherboard. ROM was used as the storage media in a Nintendo, Gameboy, and Sega Genesis game cartridge. RAM is used in computers to temporarily store files in use on the computer.

Why would eeprom be used instead of ROM?

EEPROM = electrically erasable programmable read-only memory = can be electrically erased with higher voltages (no UV light needed) in the programmer, but read-only when on the board (because erasing and re-programming mostly isn’t done on the board). So they all serve the same function: read-only memory on the board.

What happens to ROM when the computer is turned off?

ROM is memory that cannot be changed by a program or user. ROM retains its memory even after the computer is turned off. For example, ROM stores the instructions for the computer to start up when it is turned on again.

Do all computers have ROM?

Every computer motherboard includes a ROM chip that handles BIOS functionality.

Can we replace ROM?

Data stored in ROM cannot be electronically modified after the manufacture of the memory device. For example, users modifying or replacing the Android operating system describe files containing a modified or replacement operating system as “custom ROMs” after the type of storage the file used to be written to.
