RE: what is actually meant for BUFFER? how does it work
Its a temporary location where you can preserve the data. For example when you want to swap 2 nos like x 2 and y 5 so that after swaping you get x 5 and y 2. One method wud be to use a temporary variable like z and copy x value to z so z 2. Then copy y value to x so x 5. Finally copy z value to y so y 2. Here z is temporary variable and the BUFFER.

Similarly when you watch videos online all the data is copied to a temporary location or buffered and then the video can be watched. Buffers are used in almost all programming tasks. Its like a helper to your main task. It does work by itself it is used by other tasks to make a bigger task possible.
