Bandwidth

Bandwidth usually refers to the total possible flow between two nodes, such as between two computers over all their unified connections. We use the term bandwidth to describe the maximum bit rate of a system. If a network connection has a bandwidth of 100 Mbps, that means it can’t transfer more than 100 megabits per second. Bitrate usually refers to the speed of one specific connection between source and sink, such as one Internet connection or while reading an audio file.
