False

Explanation:

In pipelining, the tasks are divided into multiple stages, and each stage performs a specific operation on the data. The data flows through these stages in a pipeline fashion, with each stage working on a different task simultaneously. The goal of pipelining is to increase the overall throughput and efficiency of the system by overlapping the execution of tasks.

In a pipelined system, the tasks are divided into stages, and each stage takes a certain amount of time to complete its operation. The tasks are executed in order, and the output of one stage becomes the input for the next stage.

In pipelining, the task that takes the longest time to complete is known as the critical path. The critical path determines the overall time it takes to complete all the tasks in the pipeline. Therefore, it is important to prioritize the critical path tasks in order to minimize the overall completion time of the pipeline.

Why the answer is false:

The statement "In pipelining, the task which requires the least time is performed first" is false. In pipelining, the tasks are executed in the order they arrive, not based on their individual execution time.

The tasks in a pipeline are dependent on each other, and the output of one task becomes the input for the next task. If a task that requires less time is performed first, it may finish before the dependent tasks are ready to receive its output. This would result in idle time for the subsequent tasks, reducing the overall efficiency of the pipeline.

To maximize the efficiency of the pipeline, it is important to schedule the tasks based on their dependencies and the critical path. The critical path tasks, which take the longest time to complete, should be prioritized to ensure a smooth flow of data through the pipeline.

Conclusion:

In pipelining, the tasks are executed in the order they arrive, not based on their individual execution time. The critical path tasks, which take the longest time to complete, should be prioritized to maximize the efficiency of the pipeline. Therefore, the statement "In pipelining, the task which requires the least time is performed first" is false.
