Primary memory: Is the main memory

Primary memory is the main memory of the computer which is attached to the CPU in the motherboard. All the data required for CPU processing is stored in the primary memory. Secondary memory provides long-term storage for files and programs, retaining data safely but is slower than primary memory. In this article, we are going to discuss the difference between primary and secondary memory in detail. Introduction to Primary Memory The primary memory of a computer can be categorized into three major types. viz., a. Main memory that holds instructions and data of the current program, b. Cache memory enhances the performance of the CPU by holding a copy of instructions/data stored in the main memory to save unwanted retrieval, c. Register memory that holds information required by arithmetic and logical unit of the CPU to execute the instructions. Primary memory is the main memory of a computer system, which is used by the CPU for its internal functions. Learn about its characteristics, advantages, applications, and limitations in this tutorial.
