The term ‘aging’ refers to

  1. booting up the priority of the process in multi-level of queue without feedback.
  2. gradually increasing the priority of jobs that wait in the system for a long time to remedy infinite blocking
  3. keeping track of the following a page has been in memory for the purpose of LRU replacement
  4. letting job reside in memory for a certain amount of time so that the number of pages required can be estimated accurately.

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.

 Aging is a scheduling technique used to avoid starvationFixed 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.
