Diode :
A diode is a basic electrical device which is used as rectifier which converts an alternating current into a direct one by allowing a current to flow through it in one direction only.

Transistor :
. A bipolar transistor has terminals labeled base, collector, and emitter. A small current at the base terminal (that is, flowing between the base and the emitter) can control or switch a much larger current between the collector and emitter terminals. For a field-effect transistor, the terminals are labeled gate, source, and drain, and a voltage at the gate can control a current between source and drain.
