Memory
Computer Memory is the hardware part of the system that stores data, information, and instructions.
Types of Computer Memory
Primary Memory
Secondary Memory
Cache Memory
1. Primary Memory
Primary Memory is called as main memory of the System. During computer operations, it stores data, programs, and instructions. It is commonly called Semiconductor Memory or Volatile Memory. Primary Memory is faster than Secondary Memory.
2. Secondary Memory
Secondary Memory is used to store a heavy amount of data or information. The data or information stored in Secondary Memory is permanent and secondary memory is slower than primary memory, but secondary memory can’t be directly accessible by the CPU.
3. Cache Memory
Cache Memory is faster memory that helps in fastening the speed of the CPU. Cache Memory is used to store the data that is frequently required by the CPU. Whenever the system gets off, data present in the cache memory gets lost.
