Question

What is the major problem with priority scheduling algorithm?

• A. Starvation
• B. Deadlocks
• C. High turnaround time
• D. More process suspensions

Hint:

Priority Scheduling \(\rightarrow\) Starvation Aging \(\rightarrow\) Solution to Starvation

Answer 1

The Correct Option is A

Concept: In Priority Scheduling, CPU is allocated to the process having the highest priority.

Step 1: Understand the scheduling mechanism.
High-priority processes are executed before low-priority processes.

Step 2: Identify the drawback.
If high-priority jobs continue arriving, low-priority processes may never get CPU time. They may remain waiting indefinitely.

Step 3: Name this problem.
This indefinite postponement is called \[ \boxed{\text{Starvation}} \]

Step 4: Common remedy.
The problem is often solved using \[ \text{Aging} \] where priority gradually increases with waiting time.
