1947
in second generation of computer transistor were used transistor are used instead of vaccum tube are used in first generation high level langauges such as gobsl, fortran are used
Vcc is used in bipolar transistor circuitsVdd is used in field effect transistor circuitsB+ is used in vacuum tube circuits
it is a transistor used in IR TOGGLE SWITCH. :-)
google search engine used it all along.
second generation of computing
they invented the first transistor:)
transistor has 2 output 1 and 0 so can be used as a switch
1947 at Bell Labs. It was a germanium point contact transistor.
A transistor is used to switch electronic signals.
Its a Transistor used in JFET (Junction Field Effect Transistor)
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
before the invention of transistor,thyristor was used instead of transistor but thyristor produces more heat in the circuit and size is more when compared to transistor
