CPU Scheduling is vital for efficient operating system performance. It manages the allocation of CPU resources across competing processes, aiming to maximize CPU utilization, ensure fairness, and minimize both response time and turnaround time.
The First-Come, First-Served (FCFS) is the simplest CPU scheduling method with a queue-based operation. The first process to arrive is executed first, making it easy to implement and comprehend. However, this algorithm is non-preemptive, meaning processes cannot be interrupted once they start executing. This lack of preemption can lead to inefficiencies, such as longer wait times for shorter processes.
What is CPU Scheduling?
The process of managing the allocation of CPU time to various processes in order to maximize utilization, ensure fairness, and minimize response time and turnaround time.
What does FCFS stand for in CPU scheduling?
First-Come, First-Served, a non-preemptive scheduling algorithm that executes processes in the order they arrive.
What is the main drawback of FCFS scheduling?
It can lead to the 'convoy effect,' where shorter jobs wait behind longer jobs, potentially increasing overall response and turnaround times.
