A2. For amplification to take place, one needs three terminals; an input, an output, and a control signal.
This indicates the original " valve" naming; after a mechanical valve, where a small effort on a (hydraulic) valve may be used to control a larger effort of the controlled fluid.
A1. If u meant why diode can't be used as an amplifier diode is used as a rectifier..
it converts ac current to dc and there is an inbuilt voltage drop... so it can't be used as an amplifier

A wideband amplifier is an electronic circuit providing constant amplification with a ratio of its low corner frequency to its high corner frequency of more than an octave.
The widwband amplifier is complementary in concept to "audio amplifier" (20Hz-20KHz) and "video amplifier" (15KHz to 4.8MHZ).
The "opposite" concept is the narrow-band or tuned amplifier.
There's a new wideband amplifier technology called PowerBand from TriQuint Semiconductor.
