Question

7. Differentiate between the following in points :
(a) Primary memory and Secondary memory
(b) RAM and ROM
(c) Hard disk and Pen drive​

Answer 1

Answer:

1. Primary / Main memory:

Primary memory is the computer memory that is directly accessible by CPU. It is comprised of DRAM and provides the actual working space to the processor. It holds the data and instructions that the processor is currently working on.

2. Secondary Memory / Mass Storage:

The contents of the secondary memory first get transferred to the primary memory and then are accessed by the processor, this is because the processor does not directly interact with the secondary memory.
