8 Difference between Input and Output restricted Deque Unutilized spaces problem is overcome by circular Queues.These are used in programming languages that allow the use of fixed-size linear structure(such as arrays of c/c++ etc )as.Circular Queues are the queues implemented in circular form rather than a straight line.Deques or double ended queues are refined queues in which elements can be removed or added at either end but not in the middle. Queues are used in many computer algorithms alsoĪns.CPU uses queues to implement round-robin scheduling among waiting processes.Airport authorities make use of queues in situation of sharing a single runway of airport for both landing and take-off of flights.Sharing of one resource among multiple users or seekers such as shared printer among multiple computers Call center executive’s response among waiting callers etc. ![]() ![]() Some common applications of queues include : Applications of queues include the situations where FIFO property is exploited. 4 What are the different type of queue?Īns. Removal of element is known as Delete operation, also known as dequeuing Addition of element is known as Insert operation, also known as enqueuing, It is done using rear terminal position i.e. 3 What are the two major queue operations?Īns. Elements are always added to the rear of the queue and removed from the front of the queue i.e the element added first to the queue will be the one to be removed first. Queue is a first-in, first-out(FIFO) data structure.
