a. airline reservations.

b. payroll.

c. point-of-sale transactions.

d. air traffic control systems.

e. all of these applications typically utilize real time processing.

Answer 1

The least appropriate type of transaction for a real-time system would be:

b. payroll.

 

Explanation:

While payroll transactions require accuracy and timeliness, they do not necessarily need to be processed in real-time. Payroll processing can often be done periodically (e.g., weekly, bi-weekly, or monthly), and the immediate processing of payroll transactions is not critical for the functioning of most organizations. On the other hand, the other options (airline reservations, point-of-sale transactions, and air traffic control systems) typically require real-time processing to ensure immediate and accurate responses.

The correctio option is (b).
