Question

Which of the following is NOT correct regarding the ways that real-time systems differ from batch systems?

Real time Systems; Batch systems
a) must use direct access files; can use simple sequential files
b)processing occurs on demand; processing must be scheduled
c)processing choices are menu-driven; processing is interactive
d)supporting docs are prepared as items are processed; supporting docs are prepared during scheduled runs

Answer 1

Option c) is NOT correct as both real-time systems and batch systems can have menu-driven interfaces or interactive elements. The distinction between the two lies in the immediacy of processing and scheduling.

Step-by-step explanation:

The question asks to identify the statement that is NOT correct regarding the differences between real-time systems and batch systems. The correct answer is c) processing choices are menu-driven; processing is interactive. This statement is not true because both real-time and batch systems can have menu-driven interfaces or interactive elements; the distinction lies elsewhere.

Real-time systems process data immediately after input is received, which is necessary for tasks that require immediate response, like controlling an airplane's flight systems. Batch systems, on the other hand, process data in groups or batches at scheduled times, which is more suitable for non-immediate processing tasks, such as payroll processing.
