ECM
Error Correction Mode (ECM) is an optional transmission mode built into Class 1 fax
machines or fax modems. It automatically detects and corrects errors in the fax
transmission process that are sometimes caused by telephone line noise.
Emulation
Emulation is a technique of one machine obtaining the same results as another.
An emulator duplicates the functions of one system with a different system, so that
the second system behaves like the first system. Emulation focuses on exact
reproduction of external behavior, which is in contrast to simulation, which concerns
an abstract model of the system being simulated, often considering its internal state.
Ethernet
Ethernet is a frame-based computer networking technology for local area networks
(LANs). It defines wiring and signaling for the physical layer, and frame formats and
protocols for the media access control (MAC)/data link layer of the OSI model.
Ethernet is mostly standardized as IEEE 802.3. It has become the most widespread
LAN technology in use during the 1990s to the present.
EtherTalk
A suite of protocols developed by Apple Computer for computer networking. It was
included in the original Macintosh (1984) and is now deprecated by Apple in favor of
TCP/IP networking.
FDI
Foreign Device Interface (FDI) is a card installed inside the machine to allow a third
party device such as a coin operated device or a card reader. Those devices allow the
pay-for-print service on your machine.
FTP
A File Transfer Protocol (FTP) is a commonly used protocol for exchanging files over
any network that supports the TCP/IP protocol (such as the Internet or an intranet).
Fuser Unit
The part of a laser printer that fuses the toner onto the print media. It consists of a
heat roller and a pressure roller. After toner is transferred onto the paper, the fuser
unit applies heat and pressure to ensure that the toner stays on the paper
permanently, which is why paper is warm when it comes out of a laser printer.
Gateway
A connection between computer networks, or between a computer network and a
telephone line. It is very popular, as it is a computer or a network that allows access
to another computer or network.
Grayscale
A shades of gray that represent light and dark portions of an image when color
images are converted to grayscale; colors are represented by various shades of gray.
