Primary Storage: GCSE Computer Science Definition

What is primary storage?

In GCSE Computer Science, primary storage refers to the main memory of a computer, which includes RAM, cache, and registers. It is responsible for temporarily holding data and instructions that the CPU needs to access quickly while performing tasks.

Why is primary storage important?

Primary storage plays a crucial role in a computer’s performance. Since it is much faster than secondary storage, it allows the CPU to process data efficiently. However, most types of primary storage, such as RAM, are volatile, meaning data is lost when the computer is powered off.
