A transistor by itself cannot produce oscillations. You would need a crystal oscillator like the quartz crystal in your watch. When you appy a small amount of current, it oscillates at a certain frequency. The number of oscillations is used to calculate the time. Basically a transistor is a switch with takes a small amount of current and switches a large amount of current.

Yes - a transistor is a switch that takes a very small current to drive a higher current device. For example, the transistor can turn on / off a selenoid, or relay that controls the operation of industrial equipment.

ahh transistors are tricky things.
well they consist of a base, collector, and emitter.
a transistor by itself cannot produce an oscillation, but if you wnat to find out how it can, type in "camera flash" at howstuffworks and you'll get a good circuit
the principle is is when electricity is applied to the collector, electricity is then allowed to flow through the emitter into the base (or something like that). it explains it well in the site

It does not, it can only produce a square wave, +1 0 -1, a pair capacitor-coil generates beautiful oscillations.
