What is the history of CPU scheduling?

What is the history of CPU scheduling?

CPU scheduling has evolved significantly since the early days of computing, starting with simple methods like First-Come, First-Served (FCFS) to more complex algorithms like Round Robin and Shortest Job Next.

Can you explain how Round Robin scheduling works?

Round Robin scheduling assigns a fixed time slice to each process in a cyclic order, ensuring fair CPU time distribution among processes.

What are the advantages of using Shortest Job First (SJF) scheduling?

SJF scheduling minimizes average waiting time and is optimal for batch processes, but it can lead to starvation for longer processes.

How did the introduction of multi-core processors affect CPU scheduling?

Multi-core processors allowed for parallel processing, leading to the development of more sophisticated scheduling algorithms that can efficiently allocate tasks across multiple cores.

What are some modern CPU scheduling algorithms?

Modern CPU scheduling algorithms include Completely Fair Scheduler (CFS), Earliest Deadline First (EDF), and Multi-Level Feedback Queue (MLFQ), each designed to optimize performance based on specific workloads.
