Circular queue avoids the wastage of space in a regular queue implementation using arrays. In this tutorial, you will understand circular queue data structure and it's implementations in Python, Java, C, and C++.
It is used to allocate memory to the processes when they are in need of memory. Buffer Management: These queues are also useful in buffer management. Consider a situation where data is produced at a faster rate than it is consumed. In such cases, a circular queue is used to store the ...
This research paper focuses on enhancing the working and efficiency of statically implemented queues,(FIFO, First In First Out data structure) by some additional additive properties to it. If these properties are implemented, can abolish the concept of circular queues in "Statically implemented queues...
then a circular buffer is a completely ideal implementation; all queue operations are constant time. However, expanding a circular buffer requires shifting memory, which is comparatively[相对来说] costly. For arbitrarily expanding queues[可
which is incremented whenever a new item is pushed to the back. They can both wrap around the size of the array. Both operations are done very effectively - in constant time O(1) and no reallocations are needed. This makes circular buffers perfect solution for queues of some data streams,...

Traffic system: In computer controlled traffic system, circular queues are used to switch on the traffic lights one by one repeatedly as per the time set. CPU Scheduling: Operating systems often maintain a queue of processes that are ready to execute or that are waiting for a particular event...

Lock-free circular queues relying only on atomic aligned read/write accesses in multiprocessing systems are disclosed. In one embodiment, when comparison between a queue tail index
