ADT Queues ADT Queues Definition: Queues are ordered lists‚ which follow a FirstIn-First-Out (FIFO) order. These can be implemented as an array or using a dynamic memory allocation scheme. Queues are usually implemented using a circular array. The first element is known as the head and the last element is known as the tail. Operations: 1. Enqueue 2. Dequeue 3. FullQ 4. Makenull 5. EmptyQ 1. Enqueue { if (NumItems == MaxQueue) Success = False; //queue is full else { Rear = (Rear + 1) % MaxQueue;

random-access memory (RAM) where data is stored as well as programs that perform calculations. This is a high speed form of storing data that has the capabilities of processing a large number of data characters per second. The more RAM that a computer has‚ the faster the entire system runs. There are various types of RAM that can be found in computers. The random-access memory takes the form of integrated circuits in current times Most types of RAMS are Dynamic Random Access Memory (DRAM); they
