    A)  Floppy disk      

    B)  Magnetic tape

    C)  Optical disk      

    D)  Both 2 and 3

    E)  None of these

    Correct Answer: B

    Solution :

    [b] Magnetic tape uses sequential or serial access to locate data stored on the tape, i.e., data must be sequentially read and written as a tape is unwound, rather than retrieved directly from the desired point on the tape. Magnetic Tape is cheap, but access time is far slower than that of a magnetic disk.
