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.
