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 melts the toner onto the print media. It

consists of a hot roller and a back-up 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.

Halftone

An image type that simulates grayscale by varying the number of dots.

Highly colored areas consist of a large number of dots, while lighter

areas consist of a smaller number of dots.

HDD

Hard Disk Drive (HDD), commonly referred to as a hard drive or hard

disk, is a non-volatile storage device which stores digitally-encoded data

on rapidly rotating platters with magnetic surfaces.

IEEE

The Institute of Electrical and Electronics Engineers (IEEE) is an

international non-profit, professional organization for the advancement

of technology related to electricity.

IEEE 1284

The 1284 parallel port standard was developed by the Institute of

Electrical and Electronics Engineers (IEEE). The term "1284-B" refers to

a specific connector type on the end of the parallel cable that attaches to

the peripheral (for example, a printer).

Intranet

A private network that uses Internet Protocols, network connectivity, and

possibly the public telecommunication 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.
