A module that keeps track of elapsed time even when a computer is
turned off.
Electronic device that amplifies RF signals. A receiver separates the
audio signal from the RF carrier, amplifies it, and converts it back to the
original sound waves.
Short-term data-storage circuits within the microcontroller unit or
programmable logic IC.
Remote transmit/receive facility that re-transmits received signals in
order to improve communications range and coverage (conventional
operation).
A conventional radio feature that permits communication through a
receive/transmit facility, which re-transmits received signals in order to
improve communication range and coverage.
Reset line: an input to the microcontroller that restarts execution.
