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.
