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).

What are the difference between ascending priority queue and descending queue?
Ascending priority queue is a collection of items which can be inserted aurbitarly and which can be removed smallest item. Descending priority queue is similar to ascending priority queue but it allows the deletion of the largest item.
What are the difference between priority queue and queue?
This chapter presents two ADTs: Queues and Priority Queues. In real life a queue is a line of customers waiting for service of some kind. In most cases, the first customer in line is the next customer to be served. There are exceptions, though. For example, at airports customers whose flight is leaving imminently are sometimes taken from the middle of the queue. Also, at supermarkets a polite customer might let someone with only a few items go first.The rule that determines who goes next is called a queueing discipline. The simplest queueing discipline is called FIFO, for "first-in-first-out." The most general queueing discipline is priority queueing, in which each customer is assigned a priority, and the customer with the highest priority goes first, regardless of the order of arrival. The reason I say this is the most general discipline is that the priority can be based on anything: what time a flight leaves, how many groceries the customer has, or how important the customer is. Of course, not all queueing disciplines are "fair," but fairness is in the eye of the beholder.The Queue ADT and the Priority Queue ADT have the same set of operations and their interfaces are the same. The difference is in the semantics of the operations: a Queue uses the FIFO policy, and a Priority Queue (as the name suggests) uses the priority queueing policy.As with most ADTs, there are a number of ways to implement queues Since a queue is a collection of items, we can use any of the basic mechanisms for storing collections: arrays, lists, or vectors. Our choice among them will be based in part on their performance--- how long it takes to perform the operations we want to perform--- and partly on ease of implemen

Difference between DFS and BFS?
1. bfs uses queue implementation ie.FIFO dfs uses stack implementation ie. LIFO 2. dfs is faster than bfs 3. dfs requires less memory than bfs 4. dfs are used to perform recursive procedures.
Is the word queue a noun?
Queue can be either a noun or a verb. As a noun it can mean a waiting line, a type of hair braid, or a sequence in a computer program. As a noun, it means to form a waiting line.
What are the difference between ascending priority queue and descending queue?
Ascending priority queue is a collection of items which can be inserted aurbitarly and which can be removed smallest item. Descending priority queue is similar to ascending priority queue but it allows the deletion of the largest item.
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 are types of 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 )
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
What is the difference between queues and circular queues?
A queue can use a dynamic array, or a linked list, but if using static memory, the queue becomes a circular queue because the underlaying data structure is a static circular array. This means the ends of the array are attached.
What are the different types of queues?
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
Explai the nature of the various types queues in data structures?
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. 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)
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.
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
W difference between a linear linked list and a circular linked list?
Oh, dude, a linear linked list is like a straight line where each element points to the next one, while a circular linked list is like a loop-de-loop rollercoaster where the last element points back to the first one. So, in a linear list, you reach the end and it's like hitting a wall, but in a circular list, you just keep on looping around for eternity. It's like the difference between a dead-end street and a roundabout.
Array implementation of priority queue?
the priority queue is which depends on the data stored.in which their priority is maintained by checking the forth coming values stored in the queue
