Buffering simply means that the computers reserve enough buffer space that bursts of incoming data can be held until processed. No attempt is made to actually slow the transmission rate of the sender of the data. In fact, buffering is such a common method of dealing with changes in the rate of arrival of data that most of us would probably just assume that it is happening. However, some older documentation refers to "three methods of flow control," of which buffering is one of the methods, so be sure to remember it as a separate function.
