This is  main memory of the computer. Data This memory is stored in the data temporarily. Since this memory is expensive, its size is more limited than secondary memory. Devices used to store primary memory are called "primary storage devices". This memory holds the much lesser amounts of data that that is of immediate need. The data access speed is faster in Primary memory or in Primary Storage devices, as there is the involvement of electricity.

       Types of Primary Memory : -

                                     a.) RAM - Random Access Memory

                                     b.) ROM - Read Only Memory
