A linear queue is a linear data structure that serves the request first, which has been arrived first. It consists of data elements which are connected in a linear fashion. A circular queue is also a linear data structure like a normal queue that follows the FIFO principle but it does not end the queue, it connects the last position of the queue to the first position of the queue.
Differences between linear Queue and Circular Queue are stated below
|Basis of comparison
|The linear queue is a type of linear data structure that contains the elements in a sequential manner.
|The circular queue is also a linear data structure in which the last element of the Queue is connected to the first element, thus creating a circle.
|Insertion and Deletion
|In linear queue, insertion is done from the rear end, and deletion is done from the front end.
|In circular queue, the insertion and deletion can take place from any end.
|The memory space occupied by the linear queue is more than the circular queue.
|It requires less memory as compared to linear queue.
|The usage of memory is inefficient.
|The memory can be more efficiently utilized.
|Order of execution
|It follows the FIFO principle in order to perform the tasks.
|It has no specific order for execution.
