RAM - GCSE Computer Science Definition

What is RAM?

In GCSE Computer Science, RAM (Random Access Memory) is a type of volatile memory that temporarily stores data and instructions actively used by the CPU. It allows for quick access to data, making processing faster and more efficient compared to retrieving data from storage drives.

Why is RAM important?

RAM significantly impacts a computer’s performance. The more RAM a system has, the more programs it can run simultaneously without slowing down. However, because RAM is volatile, all data stored in it is lost when the computer is turned off.
