What is priority scheduling in operating systems?

Priority scheduling is a method where processes are assigned priority levels. Higher priority processes are executed before lower priority ones.

How does it handle processes with the same priority?

When processes have the same priority, the scheduler may use a first-come, first-served approach or round-robin scheduling.

What are the advantages of using priority scheduling?

The main advantages include improved response time for high-priority tasks and better resource utilization.

Are there any disadvantages to this scheduling method?

Yes, it can lead to starvation for low-priority processes if high-priority ones keep arriving.

Can you give an example of priority scheduling in real life?

Sure! An example is an emergency room where critical patients are treated before those with less severe conditions.
