How does priority scheduling work?

Can you explain how priority scheduling works in operating systems?

Sure! Priority scheduling is a method where processes are assigned a priority level. The CPU executes the process with the highest priority first.

What happens if two processes have the same priority?

In such cases, the operating system may use a secondary criterion, like FIFO (First In, First Out), to decide which process to execute next.

Are there any disadvantages to priority scheduling?

Yes, one major disadvantage is starvation, where low-priority processes may never get executed if high-priority processes keep arriving.

How can starvation be prevented in priority scheduling?

Starvation can be mitigated by implementing aging, where the priority of waiting processes increases over time.
