Aging is a technique in which:
- A.
The priority of a process decreases after sometime. (moves away from 1)
- B.
The priority of a process increases after sometime. (moves closer to 1)
- C.
The priority remains constant.
- D.
The process becomes old and doesn't execute.
Correct Answer
B. The priority of a process increases after sometime. (moves closer to 1)Explanation
In the technique of aging, the priority of a process increases after some time. This means that as the process continues to run, its priority gradually increases and gets closer to the highest priority level, which is represented by the value of 1. This technique is commonly used in scheduling algorithms to ensure that long-running processes are given higher priority over time, preventing starvation of lower priority processes. By gradually increasing the priority, aging helps to balance the execution time among different processes and improve overall system performance.Rate this question:

- D.
The process is executed for a time quantum and when the time quantum expires, the process enters into waiting state.
Correct Answer
D. The process is executed for a time quantum and when the time quantum expires, the process enters into waiting state.Explanation
The correct answer is that in Round Robin Algorithm, the process is executed for a time quantum and when the time quantum expires, the process enters into a waiting state. This means that each process is given a fixed amount of time to execute before it is preempted and moved to the back of the queue. This allows for fair scheduling of processes and prevents any single process from monopolizing the CPU for too long.Rate this question:
