What is the Difference Between RAM and ROM?

When talking about computers, two types of memory often come up: RAM and ROM. Even though they sound similar, they serve very different purposes.

  • RAM (Random Access Memory)

    • RAM is the temporary memory your computer uses while it’s running.

    • It stores data that your computer needs to access quickly, like open programs and active files.

    • RAM is volatile, meaning everything stored in it disappears when you turn off your computer.

    • More RAM generally means a faster and smoother computer experience.

ROM (Read-Only Memory)

    • ROM is permanent memory that holds important instructions your computer needs to start up, like the BIOS (Basic Input/Output System).

    • Unlike RAM, ROM is non-volatile, meaning its data stays even when the computer is powered off.

    • ROM is not meant to be changed or edited frequently by the user.

In Short:

  • RAM is like your computer’s short-term memory, always changing while you work.

  • ROM is like your computer’s instruction manual, staying the same to help your system boot and function.
