Characteristics of Main Memory
- Semiconductor memories.
- Faster than secondary memories.
- A computer cannot run without primary memory.
- It is the working memory of the computer.
- Usually volatile memory.
- Data is lost in case the power is switched off.

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.
