What are the types of ROM? State the difference between RAM and ROM.


ROM is further classified into four types-

  1. MROM
  2. PROM
  3. EPROM 
  4. EEPROM.

The differences between RAM and ROM are as follows:


RAM ROM
1.RAM stands for random access memory. 1.ROM stands for read-only memory.
2.It allows both read and write operations. 2.It allows only to read operation.
3.It is volatile in nature. 3.It is non-volatile in nature.
4.It is used when an IO operation is performed, known as buffering. 4.It is not used for buffering purposes.
5.It is usually has a higher memory space than ROM. 5.It usually has less memory space than RAM.
6.The second operation after booting the computer system is performed in RAM. 6.The first operation in the computer system is performed in ROM(during the booting process.)
7.It is used ti store data/instruction while they are being processed, waiting to be processed, and after being processed before it is provvided to output component. 7.It is used to store program that are required for the operation of electronic devices.
8.It is usually expensive on per unit basis but while compairing on the basis of storage capacity RAM is cheaper. 8.It is usually cheaper in terms of per unit basis but while compairing on the basis of storage capacity ROM is expensive.
9.Types of RAM are SRAM and DRAM. 9.Types of ROM are PROM,EPROM, and EEPROM.
