Explain what is SPS and its scheduling mechamism

Question

Accepted Answer

SPS stands for Scheduling Policy Subsystem. It is responsible for managing the scheduling of processes in an operating system.

SPS is a component of the operating system that handles process scheduling.
It determines the order in which processes are executed on the CPU.
SPS uses various scheduling algorithms to make decisions.
Some common scheduling algorithms include First-Come, First-Served (FCFS), Round Robin, and Priority Scheduling.
The scheduling mechanism of SPS involves maintaining a ready queue of processes and selecting the next process to run based on the scheduling algorithm.
For example, in FCFS scheduling, the process that arrives first is executed first.
In Round Robin scheduling, each process is given a fixed time slice to execute before moving to the next process.
Priority Scheduling assigns priorities to processes and executes the highest priority process first.
The scheduling mechanism aims to optimize CPU utilization, response time, throughput, and fairness.
SPS also handles context switching, which is the process of saving and restoring the state of a process when it is interrupted or preempted.
