What is the full form of EPROM in computer?
A) Erasable Programmable Read-Only Memory
B) Electronic Programmable Read-Only Memory
C) Efficient Programmable Read-Only Memory
D) Erasable Permanent Read-Only Memory
Answer:
A) Erasable Programmable Read-Only Memory
More Details on EPROM
- Erasable: Unlike ROM, which is permanent, EPROM can be erased under ultraviolet light.
- Programmable: EPROM can be programmed using special equipment.
- Read-Only Memory: EPROM is designed to store data that can only be read and not modified.
EPROM was commonly used in early computers and electronic devices due to its programmability and erasability. However, it has been largely replaced by more modern memory technologies like flash memory.
Eprom in Computer: Frequently Asked Questions (FAQs)
Q: What is the difference between EPROM and EEPROM?
A: Both EPROM and EEPROM are types of erasable memory. However, EEPROM can be erased electrically, while EPROM requires ultraviolet light.
Q: How is EPROM programmed and erased?
A: EPROM is programmed using special equipment that applies high voltage pulses to the memory cells. To erase EPROM, it must be exposed to ultraviolet light for a specific period of time.
Q: What are the advantages and disadvantages of EPROM?
- Advantages:
- Erasable and programmable
- Relatively inexpensive
- Disadvantages:
- Requires ultraviolet light for erasing
- Relatively slow compared to modern memory technologies
