local bus
On a computer with local-bus expansion capability, certain
peripheral devices (such as the video adapter circuitry) can
be designed to run much faster than they would with a
traditional expansion bus. Some local-bus designs allow
peripherals to run at the same speed and with the same
width data path as the computer's microprocessor.

MIF
Acronym for management information format. A MIF file
contains information, status, and links to component
instrumentation. MIF files are installed into the MIF
database by the DMI service layer. The content of a MIF
is defined by a DTMF working committee and is published
in the form of a MIF definition document. This document
identifies the groups and attributes that are relevant to
DMI-manageable components.
