What is the difference between ROM and RAM ?

There is one major difference between a Read-Only Memory (ROM) and a Random-Access Memory (RAM) chip: ROM can hold data without power and RAM can't. Basically, ROM is intended for lasting storage, and RAM is for temporary storage.

Alternate explanation

A ROM chip is a non-volatile storage medium, which implies it doesn't require a steady source of capacity to hold the data stored on it. By contrast, a RAM chip is volatile, which implies it loses any data it is holding when the power is turned off.

Other differences between a ROM and a RAM

  • A ROM chip is utilized primarily in the start up procedure of a PC, though a RAM chip is utilized in the ordinary activities of a PC once the operating system has been loaded. 
  • Composing data to a ROM chip is a much slower process than composing it to a RAM chip. 
  • A RAM chip can store multiple gigabytes (GB) of data, going from 1 GB to 256 GB for every chip. A ROM chip stores several megabytes (MB) of data, normally 4 MB or 8 MB for every chip.
