Solution

The correct answer is A - III, B - IV, C - II, D - I

Key Points

• A. Batch Multiprogramming
  • Batch Multiprogramming is designed to maximize processor use by running multiple jobs simultaneously.
  • Correct match: III. Maximize processor use
• B. Time sharing
  • Time sharing systems allow multiple users to interact with the system simultaneously, aiming to minimize response time for users.
  • Correct match: IV. Minimize response time
• C. Monitor
  • A monitor in computing refers to a program or a set of programs used to control the execution of other programs, ensuring that users no longer have direct access to the processor.
  • Correct match: II. User no longer has direct access to the processor
• D. Reentrant Procedures
  • Reentrant procedures are designed to be safely executed by multiple threads simultaneously, allowing more efficient use of main memory.
  • Correct match: I. Allows more efficient use of main memory

Therefore, the correct answer is: A - III, B - IV, C - II, D - I
