A batch queue is a system software data structure maintained by job scheduler software.
The process queue in an operating system is software that is not an application
Queue is difined as a special type of data structure .where elements are inserted one end &elements are deleted same end .The end from where they elements are inserted is called as "Rear end".The end from where elements are deleted is called "Front end". A linear queue is akin to the queue at the post office: it can be envisioned to be linear in space, and limited in space. When a linear queue of finite capacity is full, new arrivals are turned away (elements cannot be added, post office customers walk away). A circular queue behaves just like a normal queue, but is typically implemented in a a structure akin to a circle. The typical behavior is that the circular queue, when full, does not turn new entries away, but makes space by removing the oldest element in the queue. Of course, a queue might also be implemented to be of infinite, or virtually infinite, capacity.
LIFO is the term related to queue. It is called Last In First Out.

A 'queue' is a particular kind of data structure that Java is capable of working with. There are no products called "Java Queue" and is thus not something one can download.
There's a great class called LinkedList that implements the Queue interface. To get an instance of it, use the following code snippet: import java.util.*; Queue queue = new LinkedList<T>(); where T is the type of the objects that will go in the queue. Remember the parentheses, as they drove me crazy during one memorable day working out why exactly that same line, minus the parentheses, kept on throwing me a rather unintelligible error. Example: Queue<String> q = new java.util.LinkedList<String>() q.add("a") q.add("b") q.add("c") Calling q.getFirst() returns the value "a". Likewise, to create a Last-in first out (LIFO) collection, you use a Stack (java.util.Stack).
The queue insert operation is known is enqueue. A queue has two ends namely REAR & FRONT. After the data has been inserted in a queue ,the new element becomes REAR.The queue deletion operation is known as dequeue. The data at the front of the queue is removed .
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).......
