ROM (Read Only Memory)

What is a ROM?

The full name of ROM is Read-Only Memory, which is the primary memory of a computer. It is a permanent memory. It consists of the primary program and setting that starts the computer. It is permanently mounted on the motherboard of the computer. It is an expensive memory. It is not available separately in the market. It comes with a motherboard.

It is of three types

1.EEPROM

2.PROM

3.EPROM

Definitions:-

1.EEPROM: - Its full name is Electronic Erasable Programmable Read-Only Memory. This chip has overcome the problem of EPROM. Electricity was used to improve the program and data stored in this chip. This does not require the chip to be removed from the motherboard. This is a simple and inexpensive process. This ROM is being used in today's motherboards.

2.I. PROM: - Its full name is Programmable Read-Only Memory. The program could be stored once in this chip. If there was an error in the program, it could not be improved.

3.2. EPROM: - Its full name is Erasable Programmable Read-Only Memory. This chip had overcome the problem of PROM. The store program could be improved in this chip. To improve the chip, the chip was removed from the board and placed in front of the ultraviolet. By which the programs and data stored in the chip were deleted. The program was then stored again. Which was a difficult and expensive process

what is an output device.

An output device is a part of computer hardware that receives data from a computer and then translates that data into another form. That from many be audio, textual, visual, or hard copy such as a printed document.
