  Computer Memory And There Difference. Computer memory is an internal storage area in the computer used to store data and programs eithers temporarily or permanently. A computer memory can be divided into two groups: primary memory, secondary memory. Primary Memory It is more expensive. It is faster and more efficient than secondary memory. Directly accessed by the CPU. It is volatile in nature. Storage capacity is limited. It has no moving parts. The memory is power dependent. The memory is integrated circuit based. It consumes less power. It stores data temporarily. Secondary Memory It is cheaper. It is slower and less efficient than secondary memory. Cannot be accessed directly by the CPU. It is non-volatile in nature. It has large storage capacity. It has moving parts. The memory is power independent. The memory is magnetic or optical based. It consumes more power. It stores data permanently.
