Multiple Choice Options
- A✓ Correct Option
Uniprogramming
- B
Multiprogramming
- C
Uniprocessing
- D
Multiprocessing
Detailed Technical Solution & Explanation
In a uniprogramming operating system environment, only one single program resides in memory and executes on the CPU at any given time; all other processes must wait in external storage or idle until the currently running process finishes its execution completely.
Option Analysis:
•
Option A (Uniprogramming): Correct. Executes only one program at a time while others wait.
•
Option B (Multiprogramming): Incorrect. Multiple programs reside in memory and share CPU time.
•
Option C (Uniprocessing): Refers to having a single CPU core, not memory scheduling.
•
Option D (Multiprocessing): Uses multiple concurrent physical processors.
