hard-disk queue depth is the time it take a Hard drive in a piece of a electronic device (ex; A Desktop compter) to process a program without freezing or locking up.

### Discuss the different between queue and circular queue?

in linear queue the condition for queue full is QREAR==MAXLIMIT suppose maxlimit is ten and queue is full now if we delete 9 element from queue then inspite of queue is empty we can not insert any element in the queue. this wastage of memory is solved through circular queue where queue full condition is QREAR==Qfront+1

### Difference between queue and a circular queue?

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.

### 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…

### 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…

### 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…
