What Is RAM Memory?

RAM memory or RAM is an acronym for Random Access Memory. It can also be called: system memory, computer memory, or simply memory. Its function is to hold data that is currently used by applications and software running on the operating system. Once the application or software is closed, the resources borrowed from the RAM will go back to it.

For example – If you’re watching a movie in your computer, that video will require memory to run, so it borrows memory from the RAM in order to play the video. Because it is random access, once you are done watching your video and close it, the memory borrowed from the RAM returns.

The memory is measured in bytes. A typical size for a RAM could be 512 MB (mega bytes), 1024 MB or 1 GB (Giga Byte), 2048 MB or 2 GB.
