base address a memory address that serves as the starting address for programmable
registers. All other addresses are located by adding to the base address.
bipolar a signal range that includes both positive and negative values (for example,
–5 to +5 V)
BC buffered counter
bus the group of conductors that interconnect individual circuitry in a computer.
Typically, a bus is the expansion vehicle to which I/O or other devices are
