    A)  Direct  

    B)  Sequential

    C)  Random          

    D)         Matrix 

    E)  None of these

    Correct Answer: B

    Solution :

    [b] Sequential access method is used for obtaining a record from a cassette tape. Sequential access files are similar to cassette tapes in that each line in the file like each song on a cassette tape, is both stored and retrieved in consecutive order (sequentially). In other words, before we can record (store) the fourth song on a cassette tape, we must record songs one through three. The same is true for retrieving a song from the cassette tape.
