What is a circular buffer?

The circular buffer is either a type of hardware circuit or a computer memory that is used to store incoming information. It is a solid size buffer and can be seen as a data structure that uses a buffer as if it were connected from one end to the other. It is called a circular buffer because it gives the appearance of circulation. Adding additional information, when the buffer is complete, causes the first element stored in the buffer to be rewritten. This is also called a ring buffer or cyclical buffer. The data is always added to one end of the line and is always removed from the other end. The line head is always a slot to which the information is added; The end of the line of the line is the place from which the information is removed. The tail and head give the appearance to be side by side in implementation in this type of buffer, although in fact it is actually just a block of memory. Unlike a line in the bus station, howeverFixed buffer size and has some maximum capacity.

This means that when the buffer is full, it begins to rewrite the data in the head. The maximum buffer capacity must be set in advance, and while this number can be changed at any time, all existing data present in the buffer will be lost. Sequential processes usually use cyclic buffers to exchange information and the data entered by one process reads the other. The first process, called the producer, places the data in the buffer and the second process known as the consumer, discards it. Routines also use cyclic buffers to temporary data storage.

The most advantageous attribute of a circular buffer is the way it stores data. The data is not shuffled when the object is removed at the end of the line. If the buffer was non -policy, all the data panels present in the buffer would have toAfter deleting the data move positions. The circular buffer can be considered the first in the FIFO type (FIFO) buffer type, while the standard buffer resembles the latest type of first Out (LIFO).

Since the circular buffer stores data in neighboring areas of memory, it allows random access to data quickly. This type of buffer is easy to match and is very effective. It serves as a cache area to store a certain number of the last data. It is also possible to insert and remove data from both ends very quickly, which is ideal for many applications.
