RAM

Abbreviation for "Random Access Memory". RAM is also known as main storage or central memory and is a volatile storage. This means the storage loses its data content when there is no power anymore.

RAM exists in every computer and is needed by the CPU. It stores often needed data, like for example a picture which is just in use by the operator.

The operating system which is available in every PC enhances the requirement of central memory as it often needs many data.
