An ordinary queue requires constant time access to the first and last elements, because all insertions occur at the back of the queue and all extractions at the front. Thus we require two pointers. However, with a circular queue, the next element after the last element is always the first element, thus we gain constant-time access to both the front and back of the queue through a single pointer to the back of the queue.

What is the difference between linear and circular queue?
What is the difference between linear and circular queue? In: http://wiki.answers.com/Q/FAQ/2545-37 [Edit categories]The Queue by Default is Linear, it would be termed as Circular if the Last Element of the Queue pointsto the first element of the List
How compiler differentiate between linear queue and circular queue?
It doesn't.
Difference between simple queue and circular queue?
Simple queue is a linear queue having front & rear var to insert & delete elements from the list.But there is a boundary that we have to insert at rear & have delete from front.For this reason instead of having space in the queue if there is a single element in the rear,the queue is full.the other space is wasted.To utilize space properly,circular queue is derived.In this queue the elements are inserted in circular manner.So that no space is wasted at all.
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 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.
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 is the need of circular queue in data structures?
Circular queue is a linear data structure that follows the First In First Out principle. A re-buffering problem often occurs for each dequeue operation in a standard queue data structure. This is solved by using a circular queue which joins the front and rear ends of a queue.

Which queue most efficient queue using array?
circular queue
Difference between circular queue and linear queue?
In circular queue the memory of the deleted process can be used by some other new process..
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

Define is circular queue with example?
A circular queue uses the same conventions as that of linear queue. Using Front will always point one position counterclockwise from the first element in the queue.

What is the difference between a priority queue and a 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. 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).
