Question

Differentiate primary and secondary memory.

Answer 1

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.
