Numbers are stored as binary numbers, with each bit’s positional value significant. A computer’s main memory is divided into bytes, words or both (depending on the system), and each of these basic storage units is assigned an (72) . Using this address, the processor can read or write selected bytes or words.

During (73) , the instruction control unit fetches an instruction from main memory; during (74) , the arithmetic and logic unit executes it. Precisely timed electronic pulses generated by the clock drive this basic (75)
