local bus

from The Free On-line Dictionary of Computing (8 July 2008)

local bus

   <hardware> A {bus} connecting a {processor} to {memory},
   usually on the same {circuit board} as opposed to a
   {backplane} and therefore faster.

   Various proprietary local busses for {personal computers} are
   still in use.  The most common are {Vesa local bus} (VLB or
   VL), and {Peripheral Component Interconnect} (PCI).  Some
   computers, e.g. {notebook computers}, use a local bus with no
   expansion slots.  Previous non-local bus standards include
   {ISA}, {EISA} and {MCA}.
