Question

Which one of the following memory management schemes does not support multiprogramming?

• A. Single partition allocation
• B. Multiple partition allocation
• C. Paging
• D. Segmentation

Hint:

To support multiprogramming, the memory management scheme must allow multiple processes to be loaded into memory simultaneously, which single partition allocation does not.

Answer 1

The Correct Option is A

- Single partition allocation: In this scheme, only one process is loaded into memory, which prevents other processes from running concurrently. This does not support multiprogramming.
- Multiple partition allocation: This scheme divides memory into several parts and allows multiple processes to run at the same time, supporting multiprogramming.
- Paging: Paging divides memory into fixed-size pages, allowing multiple processes to run concurrently by loading their pages into memory,
Thus supporting multiprogramming. - Segmentation: Segmentation divides memory into logical segments, allowing processes to be loaded and run concurrently, supporting multiprogramming.
Therefore, the correct answer is 1. Single partition allocation.
