The basic difference between RAM and ROM memory is RAM is read/write while ROM Is read-only.

- A ROM, non-volatile memory, does not use to store data, but RAM is volatile and requires power to store data.
- ROM is not given usually as a specification, but RAM is typically specified when buying a computer.
- We can write data only once in ROM. However, once it is written, we can read it any number of times. RAM is the main memory in a computer, and read from and write to it much faster than other storage types. RAM is used to store files in use on the computer.
