What will be an ideal response?


Queued access methods are used when the sequence in which records are to be processed
can be anticipated, such as in sequential and indexed sequential processing. Queued
access methods perform anticipatory buffering and scheduling of I/O operations to try to
have the next record ready for processing when the previous record has been processed.The
basic access methods are normally used in situations where the sequence of records to be
processed cannot be anticipated, such as in direct access applications.
