Memory
Computer Memory is the hardware part of the system that stores data, information, and instructions. It is a device where data is stored, data is processed and instructions required for data processing are also stored. Computer memory stores both types of data that is, input and output.
Types of Computer 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.

The memory of a Computer is any physical device that is capable of storing information whether it is large or small and stores it temporarily or permanently. For example, Random Access Memory (RAM), is a type of volatile memory that stores information for a short time, on an integrated circuit used by the Operating System.
Memory can be either volatile or non-volatile. Volatile memory is a type of memory that loses its contents when the computer or hardware device is switched off. RAM is an example of a volatile memory i.e. if your computer gets rebooted while working on a program, you lose all the unsaved data. Non-volatile memory is a memory that keeps its contents saved even in the case of power loss. EPROM((Erasable Programmable ROM) is an example of non-volatile memory.
