unbuffered — Utilizes only one register for data; new data overwrites current data.
unimplemented memory location — A memory location that is not used. Writing to an
variable — A value that changes during the course of program execution.
VCO — See "voltage-controlled oscillator."
vector — A memory location that contains the address of the beginning of a subroutine written
voltage-controlled oscillator (VCO) — A circuit that produces an oscillating output signal of a
waveform — A graphical representation in which the amplitude of a wave is plotted against time.
wired-OR — Connection of circuit outputs so that if any output is high, the connection point is
word — A set of two bytes (16 bits).
write — The transfer of a byte of data from the CPU to a memory location.
