How do you test the bipolar junction transistor?

Yes, the are different names for the same thing.

amplifier, switch, oscillator, etc.

there are two characterstics of BJT,one is input and output characterstics. The output is controlled by input .

Sort of. The Bipolar Junction Transistor, or BJT, is a type of transistor. But the term transistor applies to a much wider family of components than just the Standard BJT. A rough list of the other...
