In a priority queue an element with high priority is served before an element with low priority. Queue as the name suggests is used whenever we need to manage any group of objects in an order in which the first one coming in also gets out first while the others wait for their turn like in the following scenarios.

Applications of queue data structure last updated.

Queue applications. A good example of a queue is any queue of consumers for a resource where the consumer that came first is served first. Simulation of real world queues such as lines at a ticket counter or any other. We wait in queues to buy pizza to enter movie theaters to drive on a turnpike and to ride on a roller coaster. Serving requests on a single shared resource like a printer cpu task scheduling etc.

The dequeue operation continues until the queue is reaching its last element. A typical illustration of random access is a book each page of the book can be open independently of others. The order is first in first out fifo. Another important application of the queue data structure is to help us simulate and analyze such real world queues.

Our software queues have counterparts in real world queues. In computer science a priority queue is an abstract data type similar to regular queue or stack data structure in which each element additionally has a priority associated with it. Queue follows first in first out methodology i e the data item stored first will be. Some of the applications that use queues.

Unlike stacks a queue is open at both its ends. A queue is a linear data structure that supports first in first out operation in this article we ll be discussing following algorithms and problems that can be solved directly by using queues. Operating systems schedule jobs with equal priority in the order of arrival e g a print queue. This property of queue makes it also useful in following kind of scenarios.

A queue is a linear structure which follows a particular order in which the operations are performed. Queue applications in the computer environment the below areas where the queue concept will be implemented. One end is always used to insert data enqueue and the other is used to remove data dequeue. Now the queue consists of the remaining items 5 and 8 in which the object 5 will be in the front end.

In some implementations if two elements have the same priority they are served according to the order in which. Queue is used when things don t have to be processed immediately but have to be processed in first in first out order like breadth first search. An array is a random access data structure where each element can be accessed directly and in constant time. Queue is an abstract data structure somewhat similar to stacks.
