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.
