The term ‘aging’ refers to
Can someone explain the $\mathbf A $ option?
I mean if its wrong then help me in making it true?
Do you have any idea about $\mathbf A$ option?
`JEET You can't prioritize a process in MLQ without feedback.
It can be done in MLQ with feedback, where the queues are assigned priorities (along with separate scheduling schemes, of course) and a process can be moved around within the queues to promote or demote it's priority.
Hope this helps :)
Answer : Gradually increasing the priority of jobs that wait in the system for a long time to remedy infinite blocking
A major problem with priority scheduling is indefinite blocking or starvation. A solution to the problem of indefinite blockage of the low-priority process is aging. Aging is a technique of gradually increasing the priority of processes that wait in the system for a long period of time.
ans is (b)
Aging is a scheduling technique used to avoid starvation. Fixed priority scheduling is a scheduling discipline, in which tasks queued for utilizing a system resource are assigned a priority each. A task with a high priority is allowed to access a specific system resource before a task with a lower priority is allowed to do the same. A disadvantage of this approach is that tasks assigned with a lower priority may be starved when a large number of high priority tasks are queued. Aging is used to gradually increase the priority of a task, based on its waiting time in the ready queue.
Aging is a scheduling technique used to avoid starvation In priority-based scheduling algorithms.This technique can be used to reduce starvation of low priority tasks.
