Types of Primary Storage - JSS2 Computer Studies Lesson Note

1. RAM (Random Access Memory): RAM is volatile memory that stores data and instructions for the computer to access quickly. It is used by the CPU during active tasks and is cleared when the computer is powered off. RAM is essential for running applications, operating systems, and other processes.

Cache Memory: Cache memory is a smaller, high-speed type of volatile memory located directly on the CPU or near it. It stores frequently used data and instructions to accelerate processing speed. Cache memory operates at a faster rate than main RAM, providing quick access for the CPU.
