Another commonly used term for main memory is RAM, which stands for Random Access Memory. RAM is a type of volatile memory that temporarily stores data and instructions that the CPU (Central Processing Unit) needs while performing tasks. It is called “main memory” because it plays a central role in the functioning of a computer system—serving as the workspace for active processes and operations.

When you open an application or run a program, it is loaded from the storage drive (like a hard disk or SSD) into the RAM, where the CPU can access it quickly. RAM allows for fast read and write operations, which directly impacts the overall speed and responsiveness of a system. However, RAM loses all stored information when the computer is turned off, which is why it’s referred to as volatile memory.
