PROM, EP-ROM, & EEPROM are the examples of-

A. ROM B. RAM C. Hard disk D. None of the above

Your Answer

PROM - (programmable read-only memory) is a memory chip on which data can be written only once. Once a program has been written onto a PROM, it remains there forever. Unlike main memory, PROMs retain their contents when the computer is turned off.
EPROM - (erasable programmable read-only memory) is a special type of PROM that can be erased by exposing it to ultraviolet light. Once it is erased, it can be reprogrammed. An EEPROM is similar to a PROM, but requires only electricity to be erased.
EEPROM - (electrically erasable programmable read-only memory). Pronounced e-e-prom, an EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge. Like other types of PROM, EEPROM retains its contents even when the power is turned off.
So the answer is A(ROM)
