An application suitable for sequential processing is

  • A.Processing of grades
  • B.Payroll processing
  • C.Both a and b
  • D.All of above

Answer: C

Correct answer: Both a and b

Sequential processing suits work where every record must be handled in a single run, in order - and both payroll and the processing of grades are of that kind. Nothing is gained by random access when the whole file has to be read anyway. Enquiry systems, where one record is wanted at a time, are the opposite case.
