character code that identifies a specific location (or series of locations)
in memory or on a host PC bus system

amplifier
drive that delivers power to operate the motor in response to low level
control signals. In general, the amplifier is designed to operate with a
particular motor type—for example, you cannot use a stepper drive to
operate a DC brush motor

base address
memory address that serves as the starting address for programmable or
I/O bus registers. All other addresses are located by adding to the base
address.

address.
binary
number system with a base of 2
buffer
temporary storage for acquired or generated data (software)
bus
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
connected.
