About this MCQ
This Hard Operating Systems question asks: In computer science, Mutex refers to which of the following? The correct choice is D. A synchronization object that allows only one thread to access a resource at a time.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Operating Systems items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Operating Systems so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Operating Systems item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. A user interface that allows users to interact with the operating system by issuing commands.
Why not A: “A user interface that allows users to interact with the operating system by issuing commands.” does not fit this question. The answer is A synchronization object that allows only one thread to access a resource at a time..
- B. An operating system that executes a series of jobs without user interaction, processing them in groups.
Why not B: “An operating system that executes a series of jobs without user interaction, processing them in groups.” does not fit this question. The answer is A synchronization object that allows only one thread to access a resource at a time..
- C. A memory management technique that divides memory into variable-sized segments based on logical divisions of a program.
Why not C: “A memory management technique that divides memory into variable-sized segments based on logical divisions of a program.” does not fit this question. The answer is A synchronization object that allows only one thread to access a resource at a time..
