MH
Modified Huffman (MH) is a compression method for decreasing the amount of
data that needs to be transmitted between the fax machines to transfer the
image recommended by ITU-T T.4. MH is a codebook-based run-length
encoding scheme optimized to efficiently compress white space. As most faxes
consist mostly of white space, this minimizes the transmission time of most
faxes.
MMR
Modified Modified READ (MMR) is a compression method recommended by ITU-
T T.6.
Modem
A device that modulates a carrier signal to encode digital information, and also
demodulates such a carrier signal to decode transmitted information.
MR
Modified Read (MR) is a compression method recommended by ITU-T T.4. MR
encodes the first scanned line using MH. The next line is compared to the first,
the differences determined, and then the differences are encoded and
transmitted.
NetWare
A network operating system developed by Novell, Inc. It initially used
cooperative multitasking to run various services on a PC, and the network
protocols were based on the archetypal Xerox XNS stack. Today NetWare
supports TCP/IP as well as IPX/SPX.
OPC
Organic Photo Conductor (OPC) is a mechanism that makes a virtual image for
print using a laser beam emitted from a laser printer, and it is usually green or
rust colored and has a cylinder shape.
An imaging unit containing a drum slowly wears the drum surface by its usage
in the printer, and it should be replaced appropriately since it gets worn from
contact with the cartridge development brush, cleaning mechanism, and paper.
Originals
The first example of something, such as a document, photograph or text, etc,
which is copied, reproduced or translated to produce others, but which is not
itself copied or derived from something else.
