Answer 2

"Two reasons for the use of secondary storage devices along with primary storage devices are as follows,

      • Since, primary storage devices are generally fixed at one place and not much portable, secondary storage devices can be used to add mobility/portability to data stored. Thus, secondary storage devices can be used for the purpose of transferring data and it is the best portable backup.

      • Since, the secondary storage devices are smaller in size and more portable, a person can keep it with him every time when he cannot take the computer device with him.
