A Light-Emitting Diode (LED) is a semiconductor device that indicates
the status of a machine.
Media Access Control (MAC) address is a unique identifier associated
with a network adapter. MAC address is a unique 48-bit identifier usually
written as 12 hexadecimal characters grouped in pairs (e. g., 00-00-0c-
34-11-4e). This address is usually hard-coded into a Network Interface
Card (NIC) by its manufacturer, and used as an aid for routers trying to
locate machines on large networks.
Multi Function Peripheral (MFP) is an office machine that includes the
following functionality in one physical body, so as to have a printer, a
copier, a fax, a scanner and etc.
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.
Modified Modified READ (MMR) is a compression method
recommended by ITU-T T.6.
A device that modulates a carrier signal to encode digital information,
and also demodulates such a carrier signal to decode transmitted
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.
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.
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 gray colored and a cylinder shaped.
An exposing unit of a drum is slowly worn away by its usage of the
printer, and it should be replaced appropriately since it gets scratches
from grits of a paper.
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.
Open Systems Interconnection (OSI) is a model developed by the
International Organization for Standardization (ISO) for communications.
OSI offers a standard, modular approach to network design that divides
the required set of complex functions into manageable, self-contained,
functional layers. The layers are, from top to bottom, Application,
Presentation, Session, Transport, Network, Data Link and Physical.
A private automatic branch exchange (PABX) is an automatic telephone
switching system within a private enterprise.
Printer Command Language (PCL) is a Page Description Language
(PDL) developed by HP as a printer protocol and has become an
industry standard. Originally developed for early inkjet printers, PCL has
been released in varying levels for thermal, matrix printer, and page
Portable Document Format (PDF) is a proprietary file format developed
by Adobe Systems for representing two dimensional documents in a
device independent and resolution independent format.
PostScript (PS) is a page description language and programming
language used primarily in the electronic and desktop publishing areas. -
that is run in an interpreter to generate an image.
A program used to send commands and transfer data from the computer
to the printer.
The media like paper, envelopes, labels, and transparencies which can
be used on a printer, a scanner, a fax or, a copier.
Pages Per Minute (PPM) is a method of measurement for determining
how fast a printer works, meaning the number of pages a printer can
produce in one minute.
An interface for a device driver, this allows software to interact with the
device driver using standard input/output system calls, which simplifies
A convention or standard that controls or enables the connection,
communication, and data transfer between two computing endpoints.
The Public-Switched Telephone Network (PSTN) is the network of the
world's public circuit-switched telephone networks which, on industrial
premises, is usually routed through the switchboard.
The sharpness of an image, measured in Dots Per Inch (DPI). The
higher the dpi, the greater the resolution.
Server Message Block (SMB) is a network protocol mainly applied to
share files, printers, serial ports, and miscellaneous communications
between nodes on a network. It also provides an authenticated Inter-
process communication mechanism.
Simple Mail Transfer Protocol (SMTP) is the standard for e-mail
transmissions across the Internet. SMTP is a relatively simple, text-
based protocol, where one or more recipients of a message are
specified, and then the message text is transferred. It is a client-server
protocol, where the client transmits an email message to the server.
