Whenever you need to buffer sequential data for processing in a first in, first out manner. In a multi-processing, multi-threaded environment, incoming data may be received at any time. If the function that processes that data is otherwise occupied with a datum, the new data needs to be buffered until the function is ready to deal with it, thus the data is placed in a queue.
In Windows, for instance, an application's message queue exists to buffer incoming system messages until the application's message loop is ready to deal with them. If a process is running in the same thread as the message loop, the message loop cannot process any messages in the queue until that process terminates or yields control. This is why time-intensive functions must always periodically yield control to the system to allow pending messages to be processed. If the function does not yield control, the application (and often the system itself) can appear to be completely unresponsive, making the user think the system is "hung, when it is in fact doing exactly what you told it to do.

Circular queue in linear data structure?
The queue is a linear data structure where operations of insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer.
What is different between primitive date type and non primitive data type in c plus plus programming language?
A primitive data type is built into the language - int, char, long, etc. A non-primitive data type is am abstract data type that is built out of primitive data types - linked list, queue, stack, etc.
Explai the nature of the various types queues in data structures?

Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer. A priority queue is a queue in which each element is inserted or deleted on the basis of their priority. A higher priority element is added first before any lower priority element. If in case priority of two element is same then they are added to the queue on FCFS basis (first come first serve). Mainly there are two kinds of priority queue: 1) Static priority queue 2) Dynamic priority queue A double ended queue (or deque ) is a queue where insertion and deletion can be performed at both end that is front pointer can be used for insertion (apart from its usual operation i.e. deletion) and rear pointer can be used for deletion (apart from its usual operation i.e. insertion)
What is circular queue .operations circular queue.?
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.

What are advantages and disadvantages of circular queue over ordinary queue?
Circular queues are very efficient and work well with low level codes. Ordinary queues are the standard type of queue but they do not maximize memory data well.

What ios meant by queue implementation?
In computer science, a queue is a particular kind of abstract data type or collection in which the entities in the collection are kept in order and the principal (or only) operations on the collection are the addition of entities to the rear terminal position, known as enqueue, and removal of entities.

What data is encrypted using a single key that only the sender and the recriver know?
The data itself does not matter in this scenario. The type of encryption used is symmetric encryption, meaning that the sender and receiver have the same key to lock and unlock the data.
What is circular queue operations circular queue?
A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer. There are 2 conditions for queue full if queue is implemented using arrays. First condition is Front = 1 and Rear = N Second condition is Front = Rear + 1

What is the definition of circular queue?
A queue is simply a FIFO i.e first in first out. In queue we've front and rear. Front is the initial or first location of the queue whereas rear indicates the last entry location in the queue. In the circular queue the location of front and rear will be the same IF the total space of the circular queue is utilized. Each element has its position no. for insertion , if we set the 5th element as the front element then after every insertion the ptr indicates the 5th element as front. in deletion, the fifth element is deleted every time it is the rear position. after deletion of an element the queue rotates and every time the rear indicates the 5th element of the circular queue. and every time the 5th location element is deleted.
