The memory of a computer is classified in the two categories primary and secondarymemory. Primary memory is the main memoryof the computer where the currently processing data resides. The secondary memory of the computer is auxiliary memory where the data that has to be stored for a long time or permanently, is kept. The basic difference between primary and secondary memory is that the primary memory is directly accessible by CPU whereas, the secondary memory is not directly accessible to CPU. Let us discuss some more differences between Primary and secondary memory with the help of the comparison chart shown below.

Hey there..........
Primary memory is computer memory that a processor or computer accesses first or directly. It allows a processor to access running execution applications and services that are temporarily stored in a specific memory location.
Secondary memory is computer memory that is non-volatile and persistent in nature and is not directly accessed by a computer/processor. It allows a user to store data that may be instantly and easily retrieved, transported and used by applications and services.
