system to securely share part of an organization's information or operations with its employees. Sometimes the
term refers only to the most visible service, the internal website.
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.
