What process allows a CPU to work on multiple tasks simultaneously?

• A. Task switching
• B. Pipelining
• C. Multi-threading
• D. Time-sharing

Answer: (B)

The correct answer is multi-threading. Multi-threading is a method that enables a CPU to execute multiple threads (smaller units of a process) concurrently within a single application. By allowing multiple threads to run in parallel, a CPU can efficiently utilize its resources, improving performance for applications that can perform multiple operations at the same time. It is particularly useful in modern programming, where tasks can be broken into smaller chunks for simultaneous execution, thus leading to enhanced responsiveness and better CPU utilization. Pipelining is a different concept in which multiple instruction phases (like fetch, decode, execute) are overlapped to improve instruction throughput, but it doesn’t allow for multiple tasks to run simultaneously in the sense of executing distinct operations or processes. Task switching refers to the operating system's ability to switch between different tasks or processes, but it does not mean they are running at the same time. Time-sharing is a technique that allows multiple users or applications to share system resources but also involves giving the illusion of simultaneous execution rather than true parallelism.
