UJT (UniJunction Transistor): It is a transistor with only one junction and three terminals: an emitter (E) and two bases (B1 and B2). BJT (Bipolar Junction Transistor): This type of transistor consists of two junctions and three terminals, namely Emitter "E", Base "B" and Collector"C". There are two types of BJT, i) PNP and ii) NPN.
Bipolar junction transistor(BJT)
generally bjt is faster than fets...because of many intrinsic junction capacitances between ...source and drain and bulk and gate,,,.. but now a days due to advancement in scaling fet is reduced in size sooo much that it became faster than bjt... mosfet is faster because of scaling. small channel length. even though it is slower but distance to be travelled is less

For a BJT transistor the three basic elements are collector, base and emitter. For a FET transistor are drain, gate and source which are analogous for the BJT parts mentioned before.

See for example http://www.datasheets360.com/pdf/7308997814572458562 In general, terminals are identified by number and name, with reference to the physical appearance of the transistor package.
The terminals of a BJT (bipolar junction transistor) are the emitter, base, and collector. One common method to identify these terminals is to look at the physical package of the transistor. The emitter is usually connected to the most heavily doped region and is often indicated on the package. The base is usually the middle terminal, and the collector is often connected to the remaining terminal.
Disadvantage:Easy to damage when compared to BJT

JFET (Junction Field-Effect Transistor) is a voltage-controlled device where current flow is controlled by an electric field across a semiconductor junction. BJT (Bipolar Junction Transistor) is a current-controlled device where current flow is controlled by the amount of current entering the base terminal. JFETs are majority carrier devices, while BJTs are minority carrier devices.
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
