MB Mega Byte (expressed as data rate in
MB/s or MB/second).
media capacity
The amount of data that can be contained
on a storage medium, expressed in bytes
of data.
media-type identifier
Pertaining to the bar code on the bar code
label of the IBM Ultrium Tape Cartridge,
a 2-character code, L1, that represents
information about the cartridge.
L
identifies the cartridge as one that can be
read by devices that incorporate LTO
technology;
1
indicates that it is the first
generation of its type.
mega One million of.
meter In the Metric System, the basic unit of
length; equal to approximately 39.37
inches.
micro One millionth of.
microcode
(1) One or more micro instructions. (2) A
code, representing the instructions of an
instruction set, which is implemented in a
part of storage that is not
program-addressable. (3) To design, write,
and test one or more micro instructions.
(4) See also microprogram.
microdiagnostic routine
A program that runs under the control of
a supervisor, usually to identify field
replaceable units.
microdiagnostic utility
A program that is run by the customer
engineer to test the machine.
microinstruction
A basic or elementary machine
instruction.
microprogram
A group of microinstructions that when
run completes a planned function.
The term microprogram represents a
dynamic arrangement or selection of one
or more groups of microinstructions for
execution to run a particular function. The

whose contents are not lost when power
is cut off.
O
oersted
The unit of magnetic field strength in the
unrationalized centimeter-gram-second
(cgs) electromagnetic system. The oersted
is the magnetic field strength in the
interior of an elongated, uniformly
wound solenoid that is excited with a
linear current density in its winding of
one abampere per 4
π
centimeters of axial
length.
offline
Pertaining to the operation of a functional
unit without the continual control of a
computer. Contrast with online.
