RAM and ROM

RAM and ROM

1. ROM

   • Read only memory
     • Mainly used for firmware or other things that don't require many updates.
   • Used in computing in places where files wont have to be altered very much

2. RAM

   • Random access memory
     • Used to run everything from the OS to programs on the computer

3. The difference between RAM and ROM is that ROM is read only. RAM can be randomly accessed by the computer to store values and data

4. The reason we need ROM in a computer is because its a cheaper component than RAM. ROM is used in firmware, as files don't have to be modified.

5. We need RAM so that the operating system and programs can concurrently store data and values. RAM can be written and overwritten, so RAM doesn't run out.
