= describe how diff functional units (registers and alu particularly) are connected. System bus = set of wires in the cpu that connects all components. Data bus = transports individual words of data btwn memory, registers and alu. The only way to get a data word frm memory to register and vice versa: load value @ address into mbr from memory, then into ac. Selects memory address that cpu reads frm/writes to. Cpu puts value (for eg 005) into mar, which tells memory to activate address [005] Used by control unit to select diff op modes or other components.
