Question

What is Buffer?

Accepted Answer

Buffer is a temporary storage area in computer memory used to hold data that is being transferred between devices or processes.

Buffers are commonly used in programming to improve performance by reducing the number of read and write operations to a disk or network.
They can also be used to smooth out the flow of data between devices that operate at different speeds.
Examples of buffers include the keyboard buffer, which temporarily stores keystrokes until they can be processed by the computer, and the print buffer, which holds data until it can be printed.
In networking, buffers are used to hold packets of data until they can be transmitted over the network.
In audio and video streaming, buffers are used to store a small amount of data to ensure a smooth playback experience.
