what is a transistor
semiconductor which controls voltage or flow of current and acts as a switch (can also amplify)
what are logic families
Logic families are different types of technologies being used to build different logic gates.
positive logic - high voltage 1
negative logic - high voltage 0
Unipolar (MOS - CMOS, NMOS, PMOS)
Bipolar (Saturated - TTl, Unsaturated - ECL)
