What are the differences between ROM and RAM

ROM (Read only memory)

  1. You can only read the data.
  2. Data can’t be written every time, to write the data we need PROM, EPROM, OR EEPROM.
  3. ROM is non volatile in nature. The data stored in ROM is permanent in nature.
  4. Size of the ROM has nothing to do with processing.

RAM (Random access memory):

  1. You can read and write data on the chip.
  2. RAM has volatile memory. It looses its contents when the power is switched off.
  3. Size of the RAM makes difference in the processing i.e., bigger the size of the RAM more is the speed of processing.
  4. The data can be read and written at anytime.
