A diode allows current to pass in one direction only, and has two pins - Anode and Cathode. A transistor is a switch that has three pins - Collector, Base, Emitter, and a current can pass between the collector and emitter if there is a current on the base.
A picture of diodes and transistors can be found here (left to right: diode, transistor, transistor, LED - diode that lights up):

Electronic parts which is designed to make several type of electronic circuits. Contains semi-conductors, mainly Si(Silicon) and Ge(Germanium).
Silicon
it converts it to a diode. sometimes this is done for matching the characteristics of diodes and transistors in the circuit. standard diodes might not have similar enough curves to the transistors for the circuit to operate correctly.
no, the shared base of a transistor between the emitter & collector must be thin to get the transistor effect. the thinner the better for high frequency transistors. this cannot be faked using individual discrete diodes.
Eniac didn't have any transistors. It was built with 17,468 vacuum tubes, 7,200 crystal diodes, and a whole host of other components. But no transistors. The first transistor was created in November, 1947, almost two years after Eniac was completed.
Yes. In electronic devices, semiconductors fulfill a variety of functions, including current filtering - a semiconductor diode only lets current pass in one direction - and signal amplification, using transistors. Transistors have many uses, including for electronic switching. Do some reading on diodes and transistors, while bearing in mind that they use semiconductors.Yes.

To bias the transistors at 0.7 Volts.

Solid state electronics (diodes and transistors primarily)
You probably will destroy the diodes in the alternator and any other electronic equipment that includes transistors or diodes.

Because they are different transistors. Resistance among their internal diodes is one of the main features of a transistor.

That depends:simple passive circuits have no transistorsvacuum tube circuits have no transistorssolid state circuits can have anywhere from no transistors (just diodes and/or magnetic amplifying transformers) to as many transistors as needed to perform the function
A transistor is made up of two diodes back-to-back. In a common base circuit - the load is shared between two diodes
no,we cant use transistor by combination of two diodes because we will come across a condition called current hogging.it means large amount of current flows through the device,diode can just rectify the signal but not amplifies it. Transistors however, can be used as diodes.
