Which of the following best describes the First-In/Last-Out (FILO) queuing discipline?

The First-In/Last-Out (FILO) queuing discipline operates on the principle that the most recently added entity is the first to be removed from the queue. This means that entities exit the queue in reverse order of their arrival. For example, if three entities enter the queue one after the other, the last one that arrived will be the first to leave when it is time for processing. This system is akin to a stack of items, where the last item added is the first one to be taken out.

Understanding FILO is crucial, particularly in contexts like data management or specific types of service delivery where the most recent requests or transactions may need to be prioritized over the earlier ones. This method may be used in scenarios where timely processing of the latest data or requests is essential, thereby facilitating a more responsive system to immediate needs.
