Transistors are Bi-polar PN Junction devices (BJT's) which switch or amplify current and come in PNP and NPN types which dictate base to emitter bias conditions. BJT's commonly have three terminals b (base), e (emitter), and c (collector) which by internal design provide an hFE or dc current gain which is needed to produce larger currents from varying smaller currents. There are two p-n junctions : base/emitter and base/collector with BJT transistors. For this reason transistors are commonly used as simple current switches or amplifiers. Without the transistor there would essentially be no computers since there would have never been any mechanism by which to construct logic devices like OR Gates, AND Gates, NAND Gates, Flip-Flops, Inverters and Buffers. Transistor Switches In a simple switch application the transistor is placed in cutoff mode (off) or saturation (on). The on/off condition of a transistor is affected by a base-emitter bias versus the dc hFE. In a simple logic application where a digital signal is produced the NPN type transistors base-emitter bias current is high enough to saturate the transistors emitter-collection region with current. When the emitter collector region becomes saturated (both junctions forward-biased) a logic low (Vce =0) will be produced across the collector emitter terminals since current is flowing. By simply removing or lowering the base/emitter forward-bias current the transistor will move from saturation (Vce=0) to cutoff where the Vce is equal to Vcc.

If inceres the base voltage of transistor them it may be burn . The base volt may be 0.8v to 1.8 If it use as a amplifier
there are two diodes there but to use them as rectifiers never
Direct coupled transistor logic is a type of transistor that is more economical to use then integrated circuits. These transistors can be found in many types of wires such as the ones that control cable internet.
You need a positive input to operate the transistor and since most circuits are negatively grounded when the transistor is not in use it has a negative input current thus using less power most of the time.
An unbiased transistor is one being used with no bias voltage to offset its operating point. If the input signal is very small it still can operate as an amplifier but the output will be non-linear. One use for an unbiased transistor is when the transistor is used as a switch, turning it on or off.
