  bus
       
           One of the sets of conductors (wires, PCB
          tracks or connections in an integrated circuit) connecting
          the various functional units in a computer.  There are
          busses both within the CPU and connecting it to external
          memory and peripheral devices.  The data bus, address bus
          and control signals, despite their names, really constitute a
          single bus since each is useless without the others.
       
          The width of the data bus, i.e. the number of parallel
          connectors, and its clock rate determine its data rate (the
          number of bytes per second which it can carry).  This is one
          of the factors limiting a computer's performance.  Most
          current microprocessors have 32-bit busses both internally
          and externally.  100 or 133 megahertz bus clock rates are
          common.  The bus clock is typically slower than the processor
          clock.
       
          Some processors have internal busses which are wider than
          their external busses (usually twice the width) since the
          width of the internal bus affects the speed of all operations
          and has less effect on the overall system cost than the width
          of the external bus.
       
          Various bus designs have been used in the PC, including
          ISA, EISA, Micro Channel, VL-bus and PCI.  Other
          peripheral busses are NuBus, TURBOchannel, VMEbus, MULTIBUS and
          STD bus.
       
          Some networks are implemented as a bus at the physical
          layer, e.g. Ethernet - a one-bit bus operating at 10 (or
          later 100) megabits per second.
       
          The term is almost certainly derived from the electrical
          engineering term "bus bar" - a substantial, rigid power supply
          conductor to which several connections are made.  This was
          once written "'bus bar" as it was a contraction of "omnibus
          bar" - a connection bar "for all", by analogy with the
          passenger omnibus - a conveyance "for all".
