Both of them are pointing to the last element in Q. With every deletion F is incremented as follows, in this step we end up F = 4 and R = 4. So, at the end we have F = 0 and R = 4 (or N-1). Next, R is incremented for the rest of the insertions. When 4 is inserted, R = 0 and F = 0 (F is incremented in insertion of first element). Initially, Q is empty and R and F is set to -1. The queue pointers- Rear Pointer represented by R and Front Pointer represented by F. Unlike traditional queues, a circular queue optimizes space by overwriting old entries when full, enabling continuous operation and execution management within computing environments.Įxplanation: In the figure above, we see that there is a simple queue(Q) with maximum size, N = 5. Often termed 'Ring Buffer,' this data structure efficiently stores processes, ensuring seamless resource allocation. Explore the utility of circular queues in operating systems, crucial for managing process execution through FIFO principles.
