batch. It is best suited to applications having large volumes of similar transactions
that can be processed at regular intervals

networks that have evolved and are now made up of millions of computers and
subnetworks throughout the world
sequential access - ANSWER:files store records in sequence, with one record stored
immediately after another. The sequence is usually based on a key field such as

the computer to find a record among the random records using a randomized
formula
