Answer 2

Secondary Storage Unit holds data permanently.

• It is also known as auxiliary memory.
• It is larger in storage capacity than main memory and can be stored permanently on it.
• It is slower than main memory.
• It is cheaper in terms of cost per unit data.
• It can retain the data or information stored in it even the computer system switches off or resets and that's why secondary memory is non-volatile.
• In this memory, the stored pieces of data cannot accessed directly by CPU.
• The most commonly used secondary storage medium is magnetic disk.
