Introduction to Primary Storage Systems - JSS2 Computer Studies Lesson Note

Primary storage, also known as main memory or RAM (Random Access Memory), is a crucial component in a computer system. It is responsible for temporarily storing data and instructions that the CPU (Central Processing Unit) actively uses during operations. Primary storage provides fast and direct access to data, enabling efficient processing and retrieval.

Primary storage plays a pivotal role in the functioning of a computer system. It is where the operating system, application software, and currently processed data reside. When you open a program or work on a document, the relevant data is loaded into primary storage for quick access by the CPU. The speed and efficiency of primary storage directly impact the overall responsiveness and performance of the computer.
