what is prom in computer
PROMs (or programmable read only memory) are blank chips which have nothing recorded on them. Once a series of instructions or data are recorded into the chip by a special programming device, the PROM chip permanently stores this information like ROM. The programming of the PROM chip is generally done by the manufacturer of the computer systems. PROM chips are used primarily to provide special purpose programs such as games and graphics, which can be plugged into the main computer board.
