ROM (read-only memory) is a computer memory on which data is stored. Once data is stored onto a ROM chip, it can’t be erased and can only be read. It even holds its contents even if the PC is switched off.
The majority of PCs have a small amount of ROM that stores important programs for instance the program that boots the computer. More over, ROMs are used widely in calculators and other devices like laser printers, whose fonts are also saved in ROMs.
