Computer memory is one of the most crucial components in any computing device, responsible for storing and retrieving data quickly. It plays a significant role in determining the speed, performance, and efficiency of a computer system. Without sufficient memory, even the most powerful processors cannot function effectively.

Types of Computer Memory

Computer memory is broadly classified into two categories: primary memory and secondary memory. Primary memory, often referred to as volatile memory, includes Random Access Memory (RAM). It temporarily stores data and instructions that the CPU needs while performing tasks. Once the computer is turned off, the data in RAM is lost. On the other hand, secondary memory, or non-volatile memory, includes storage devices such as hard drives, SSDs, and optical discs, where data remains even when the power is off.
