Final answer:
The statement is true; FCFS scheduling can lead to high variability in response times since tasks are processed in the order they arrive, without prioritization based on task length.
Step-by-step explanation:
True or False: One may experience a higher variance in response time for FCFS. The statement is true. First-Come, First-Served (FCFS) is a scheduling algorithm where requests are processed in the order they are received. Variance in response time refers to how much the response times deviate from the average. With FCFS, certain tasks may have to wait for a long time if a task with a long processing time arrives before them. This leads to high variance in response time, as some tasks are served quickly and others with significant delay.
In contrast, scheduling algorithms that prioritize short tasks or those based on priority levels aim to reduce this variability and balance load more effectively. The variation in response times can be exemplified by comparing scenarios with uniform wait times versus those with variable wait times due to tasks with fluctuating execution times.
