SERIAL TRANSFER causes all bits of data to be transferred on a single line.
PARALLEL TRANSFER has each data bit on its own line.
SCALING of binary numbers means to increase or decrease the magnitude of a number by a power
of 2.
LOGIC FAMILIES are composed of logic circuits based on particular types of elements.
