Which of the following is not the type of queueQuestion 6Answera.Single ended queueb.Circular queuec.Ordinary queued.Priority queue

To determine which option is not a type of queue, let's analyze the options provided:

1. Single Ended Queue: This is essentially the linear queue, where insertion and deletion occur from one end, which is the front end of the queue.

2. Circular Queue: This type of queue connects the last position back to the first position, creating a circular structure, which helps in efficiently utilizing space.

3. Ordinary Queue: This term is not standard in computer science terminology. The typical terms used are linear queue, circular queue, and priority queue. Thus, it seems that this is an ambiguous or non-standard term.

4. Priority Queue: This is a special type of queue where elements are removed from the queue based on priority rather than the order of arrival.

Analysis

From the analysis, we can conclude that "Ordinary Queue" is the term that does not represent a commonly accepted type of queue in computer science.

Final Answer
