Why is a device such as a tape-drive a poor secondary storage device for Random/Direct access to a file?

Solutions

Expert Solution

Tapes are Sequential Access device i.e we can access recors sequence by sequence.
Suppose I want the 10th record from Tape, So we need to traverse from 1,2...10th to get the 10th record because they access in sequential manner .

So any random access will make our lifes too complicate dbecause we need to start from begeinning to get the random record and it might be very expensive operation to get all the random records

Hence they are poor secondary storage device for Random/Direct access to a file

Also we know secondary storage are slow i.e the time take to get the records takes more time than Cache/RAM
