What is an integrated circuit?

Technician A says diodes are used to rectify the voltage produced from an AC generator. Technician B says a zener diode protects circuit components from voltage spikes. Who is correct?

The clock in a computer is needed to maintain the orderly flow of information throughout the computer's circuitry by transmitting one bit of binary code for each clock pulse.

Semiconductors are made of ______.

On today's vehicles, ____________________ diodes are commonly used to prevent voltage spikes in circuits as magnetic fields collapse.

Which of the following is NOT a name for a transistor leg?

Reflashing a computer requires that the computer be removed from the vehicle and sent back to the manufacturer for reflashing.
