A computer has 128GB of word addressable memory and a word size of 32 bits. The word size tells you not only how large a datum is but is also needed to determine the size of an address. The computer is able to send 2 words at a time over the database. The computer has 82 control signals that it sends from the control unit out onto the system bus and there are 32 devices that can send interrupt signals to the CPU. Use this information to determine the size of the system bus in bits, showing each of the size of the address bus, data bus, control bus and the overall size of the bus.
