Hi there! here is the answer:
___________________________
□ SEQUENTIAL ACCESS METHOD
In this method records must be read in the same order as they were returned to the storage media.
The best example of these kinds of storage media is magnetic tape. The magnetic tape allows only sequential access to data.
□ RANDOM ACCESS METHOD
This method allows immediate direct access to individual records in a file.
It is widely used today whenever the computer configuration includes CRT terminals that display management information on demand.
