IP address
An Internet Protocol (IP) address is a unique number that devices use in
order to identify and communicate with each other on a network utilizing
the Internet Protocol standard.
IPM
The Images Per Minute (IPM) is a way of measuring the speed of a
printer. An IPM rate indicates the number of single-sided sheets a printer
can complete within one minute.
IPP
The Internet Printing Protocol (IPP) defines a standard protocol for
printing as well as managing print jobs, media size, resolution, and so
forth. IPP can be used locally or over the Internet to hundreds of
printers, and also supports access control, authentication, and
encryption, making it a much more capable and secure printing solution
than older ones.
IPX/SPX
IPX/SPX stands for Internet Packet Exchange/Sequenced Packet
Exchange. It is a networking protocol used by the Novell NetWare
operating systems. IPX and SPX both provide connection services
similar to TCP/IP, with the IPX protocol having similarities to IP, and
SPX having similarities to TCP. IPX/SPX was primarily designed for
local area networks (LANs), and is a very efficient protocol for this
purpose (typically its performance exceeds that of TCP/IP on a LAN).
ISO
The International Organization for Standardization (ISO) is an
international standard-setting body composed of representatives from
national standards bodies. It produces world-wide industrial and
commercial standards.
ITU-T
The International Telecommunication Union is an international
organization established to standardize and regulate international radio
and telecommunications. Its main tasks include standardization,
allocation of the radio spectrum, and organizing interconnection
arrangements between different countries to allow international phone
calls. A -T out of ITU-T indicates telecommunication.
ITU-T No. 1 chart
Standardized test chart published by ITU-T for document facsimile
transmissions.
JBIG
Joint Bi-level Image Experts Group (JBIG) is an image compression
standard with no loss of accuracy or quality, which was designed for
compression of binary images, particularly for faxes, but can also be
used on other images.
JPEG
Joint Photographic Experts Group (JPEG) is a most commonly used
standard method of lossy compression for photographic images. It is the
format used for storing and transmitting photographs on the World Wide
Web.
LDAP
The Lightweight Directory Access Protocol (LDAP) is a networking
protocol for querying and modifying directory services running over
TCP/IP.
LED
A Light-Emitting Diode (LED) is a semiconductor device that indicates
the status of a machine.
MAC address
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.
MFP
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.
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 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.
