Thermionic valve
BJT is Bipolar junction transistor FET is Field effect Transistor It is a current controlled device It is voltage controlled device
In the transistor, first letter denotes the material and the second letter denotes about the type of device. Hence here in sk100 transistor, first letter s denotes that it is a silicon transistor and second letter k denotes that it is a hall effect device.So, sk100 is a hall effect silicon transistor....
FET is abbreviation of Field Effect Transistor. This is a transistor in which current is controlled by voltage only and no current is drawn. It is a high input impedence device and is used in computers, telecommunication and control circuits. This transistor is better in certain parameters as compared to BJT, that is Bipolar Junction Transistor.
CMOS stands for 'Complementary Metal Oxide Silicon' and is the construction method of the device. FET stands for 'Field Effect Transistor'. Although it is a transistor and is used in a similar fashion, it is totally different in the way it is controlled and biased. The pin outs are named differently. A bipolar transistor has a Base Emitter and Collector. A FET has a Drain Source and Grid. Current is controlled between the 'Source' and 'Drain' by altering the voltage on the grid. It works in a similar way to the old vacuum tube valves and is why the control is called a grid. It forms a 'pinch off' effect, in the path between the source and drain, instead of the depletion layer in a normal transistor.
MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.
Its a Transistor used in JFET (Junction Field Effect Transistor)
A transistor (bipolar junction transistor BJT) will only conduct in ONE DIRECTION. And the voltage drop is not Ohmic - it is *NOT* strictly related to current flow. If you're referring to a Field-Effect Transitor (JFET, IGFET, MOSFET, etc), then the device may be able to be used in a bidirectional circuit. But the question stated "transistor", which is understood to be a BJT.

The transistor was created by researchers at the university of Geneva. "The first patent for a field-effect transistor principle was filed in Canada... 1925. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor."

Field Effect Transistor A: basically a silicon bar where the conduction is controlled by a field since there is no connection to the gate the impedance is very high
Metal Oxide Semiconductor. Usually used when referring to a specific type of transistor which uses this type of semiconductor material: the Field Effect Transistor (FET).
