The transistor is an electronic switch or amplifier
that, unlike its predecessor (the tube) is relatively
low voltage and power.
Most transistors (NPN, PNP) had 3 wires going
into them (base, collector, emitter). They ranged
in size from about 1mm across to 2cm across
(at the absolute largest).
However, modern computers have hundreds
of thousands of switches, so as small as the
transistor was for its time, it wasn't small enough.
Many many many of them can now be condensed
onto wafers of silicon creating microchips, which
are the building blocks of pretty much all modern
electronics.

Transistors, aks semiconductors, took the place of the old vacuum tubes in electronic gadgets, but now transistors are also obsolete, giving way to integrated cirsuits. In fact, all individual components [resistors, capacitors, coils, chokes, etc.] are getting scarcer and scarcer to find in use in todays electronics.

yeah, went to tech school, didn't see much of use of transistors. ICs really did take over. Yeah i didn't even give you anwer =( it is to amplify an input signal though.
