Q
What is secondary storage?
A
Secondary storage is also known as backing storage.
Data from the memory is written in the secondary storage when the data is no longer being actively used, for retrieval at a later time.
The time a computer takes to access data stored on secondary storage is longer than the time it takes to access data from memory.
