It's very similar to real-world queues. Queues can be used for various purposes. For example if there are multiple tasks that are waiting to be executed, then they will wait in a queue for their turn to come. Another use is when some resource (say your printer) is needed by various tasks for their successful and complete execution. These tasks will then wait in the queue for their turn as each task in front of them uses and releases the printer and then exits the queue.
Basically a queue is a First In First Out (FIFO) structure. This means, that like real-world queues, the first task to enter the queue will be the first to execute or obtain its required resources. Any other tasks that come after it are added to the rear end of the queue and from there they move to the front of the queue one-by-one as their turn comes up.
Hope that helps.

The queue is the the concept involved in Algorithms where you use stack, queue and lists to store the different data items e.g people waiting for the bus at bus stop the first in queue will enter first this is called FIFO (first in first out).......

An operating system is a necessary concept of using a modern computer. It is not a matter of "popularity."
A batch queue is a system software data structure maintained by job scheduler software.
An empty set is called a null set. Testing whether a set (or a list, stack, queue) is empty or NULL is an essential concept in both number theory and computer science.
The purpose of a queue system is quite simple - it allows and maintains order in any situation where there is more than one person waiting for a service.
What is the concept of a system.
A queue management system is used for managing queues in queueing areas, such as, in cinemas, retail stores, hospitals, embassies and transportation stations. Queue management system helps to reduce the time used in queueing,especially with the use of ticket.
There are several computer application in management information system. These are application systems that aids the management in decision making. Example of which are: business intelligence system,...
People who are looking for a queue management system could try to contact companies like Supalocal or AKIS Technologies. In the end there are lots of vendors selling this products.
A queue is a data structure that allows adding elements at one end (the tail of the queue), and removing them from the other end (the head).Adding at the tail is sometimes called enqueueing, and removing from the head is dequeueing.Inserting or removing elements at other places is not permitted.There may also be operations to examine the element at the head of the queue without removing it (peeking), and to find out how many elements there are in the queue.
Queue is a data structure which is based on FIFO that is first in first out. Following are the types of queue: Linear queue Circular queue Priority queue Double ended queue ( or deque )
