COMPUTER FUNDAMENTALS

Detailed explanation-1: -Secondary Memory: It is the storage that the CPU cannot access directly. it’s content firstly needs to be copied into ram and then transferred to CPU. It stores data that can be easily retrieved only by the main memory and used by the processor.

Detailed explanation-2: -The CPU cannot access secondary storage directly. Instead, the information is copied from the secondary storage to primary memory, where it can be “used".

Detailed explanation-3: -A direct access storage device is a type of secondary storage device that supports direct access to stored data, as opposed to sequential access, which is slower and less efficient.

Detailed explanation-4: -Auxiliary memory, also known as auxiliary storage, secondary storage, secondary memory or external memory, is a non-volatile memory (does not lose stored data when the device is powered down) that is not directly accessible by the CPU, because it is not accessed via the input/output channels (it is an external device).
