ROM is a storage system that holds valuable data that your computer needs to run properly
Remembering The Important Stuff
A computer relies on ROM to store information for the computer's most critical programs. Many of these programs and platforms provide instructions to the hard drive, and they are designed to open each time a computer is booted up. A component known as the BIOS system is stored in ROM, and this gives the computer instructions on how to boot up. In this way, ROM helps your computer wake up.
