How do scheduling algorithms affect system performance?

What are scheduling algorithms and why are they important for system performance?

Scheduling algorithms are methods used to allocate resources to processes in a system. They are crucial because they determine how efficiently tasks are executed, impacting overall system performance.

Can you explain the different types of scheduling algorithms?

Sure! Common types include First-Come, First-Served (FCFS), Shortest Job Next (SJN), Round Robin (RR), and Priority Scheduling. Each has its pros and cons depending on the system's needs.

How does Round Robin scheduling work?

Round Robin scheduling assigns a fixed time slice to each process in a cyclic order. This ensures that all processes get an equal share of CPU time, which can improve responsiveness in time-sharing systems.

What impact does the choice of scheduling algorithm have on system performance?

The choice of scheduling algorithm can significantly affect CPU utilization, response time, and throughput. For example, a well-suited algorithm can minimize wait times and maximize resource use, leading to better overall performance.
