Disadvantage:Easy to damage when compared to BJT
It helps us to select the Q - point of the BJT, MOSFET etc.
In the early 1960s it was, I've seen the devices.
BJT is Bipolar junction transistor FET is Field effect Transistor It is a current controlled device It is voltage controlled device
it is an oscillator
For MOS fabrication, wafers with crystal orientation <100> are used. This helps achieve a lower threshold voltage and for BJT <111> orientation is preferred.

ApplicationsThe BJT remains a device that excels in some applications, such as discrete circuit design, due to the very wide selection of BJT types available, and because of its high transconductance and output resistance compared to MOSFETs. The BJT is also the choice for demanding analog circuits, especially for very-high-frequencyapplications, such as radio-frequency circuits for wireless systems. Bipolar transistors can be combined with MOSFETs in an integrated circuit by using a BiCMOSprocess of wafer fabrication to create circuits that take advantage of the application strengths of both types of transistor.

Bipolar junction transistor(BJT)
the common collector can use as voltage buffer
It helps us to select the Q - point of the BJT, MOSFET etc.
You can use an npn or a pnp bjt in a common emitter amplifier circuit. The decision of which one to use is based on whether you want the collector and base to be more positive (npn) or more negative (pnp) than the emitter.

Three.
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
its kind of fabrication in which without bure in the sheet metal , fabrication to be done.
