Double buffering uses two buffers allowing simultaneous data transfer while one buffer is processed, but may fail under burst traffic. Circular buffering employs multiple buffers to effectively manage continuous I/O operations, especially during rapid bursts. The structure treats the buffers as connected end-to-end, allowing for more efficient data handling during high demand.

What is the difference between double buffering and a circular buffer-.docx
- 1. What is the difference between double buffering and a circular buffer? Solution DOUBLE BUFFERING : It uses two system buffers . A process can transfer data to or from one buffer while the operating system empties or fills the other buffer.Computation and Memory copy can be done in parallel with transfer. It may be insufficient for really burst traffic as lots of application writes between long periods of application computation . While CIRCULAR BUFFERING uses more than two buffers and each individual buffer is one unit in a circular buffer.They are used when I/O operation must keep up with process.During rapid burst of I/O operation by a process,Double buffering may be inadequate and the problem can often be alleviated by using more than two buffers. When more than two buffers are used, the collection of buffers is itself referred to as a circular buffer with each individual buffer being one unit in the circular buffer. A circular buffer is a data structure that uses a single, fixed-size buffer as if it were connected end-to-end.
