The document discusses the three main types of computer memory: cache memory, primary/main memory, and secondary memory. Primary memory, also known as main memory, is random access memory (RAM) and is used by the computer to run programs and actively store and access data. Secondary memory includes storage devices like hard disks that can hold larger amounts of data but are slower to access.
