Basically, the transistor is a solidstate device that amplifies by controlling the flow of current carriers through its semiconductor materials. This will lead naturally to our discussion of digital systems. In certain cases, the quoted collector current may be exceeded. They may be viewed as electronic valves because a small signal that is sent through a middle terminal controls the current flow through the others.
