There is no universal "best" scheduling algorithm, and many operating systems use extended or combinations of the scheduling algorithms above. For example, Windows NT/XP/Vista uses a multilevel feedback queue, a combination of fixed-priority preemptive scheduling, round-robin, and first in, first out algorithms.

WhatsApp: +86 18221755073A queue is a FIFO (First-In, First-Out) data structure in which the element that is inserted first is the first one to be taken out. The elements in a queue are added at one end called the REAR and removed from the other end called the FRONT.Queues can be implemented by using either arrays or linked lists. This makes queue as FIFO(First in …

WhatsApp: +86 18221755073The Queue class represents a first-in-first-out (FIFO) queue of generic items. It supports the usual enqueue and dequeue operations, along with methods for peeking at the first item, testing if the queue is empty, and iterating through the items in FIFO order.. This implementation uses a singly linked list with a static nested class for linked-list nodes.
