DLNA

The Digital Living Network Alliance (DLNA) is a standard that allows

devices on a home network to share information with each other across

the network.

DNS

The Domain Name Server (DNS) is a system that stores information

associated with domain names in a distributed database on networks,

such as the Internet.

Dot Matrix Printer

A dot matrix printer refers to a type of computer printer with a print head

that runs back and forth on the page and prints by impact, striking an

ink-soaked cloth ribbon against the paper, much like a typewriter.

DPI

Dots Per Inch (DPI) is a measurement of resolution that is used for

scanning and printing. Generally, higher DPI results in a higher

resolution, more visible detail in the image, and a larger file size.

DRPD

Distinctive Ring Pattern Detection. Distinctive Ring is a telephone

company service which enables a user to use a single telephone line to

answer several different telephone numbers.

Duplex

A mechanism that will automatically turn over a sheet of paper so that

the machine can print (or scan) on both sides of the paper. A printer

equipped with a Duplex Unit can print on both sides of paper during one

print cycle.

Duty Cycle

Duty cycle is the page quantity which does not affect printer

performance for a month. Generally the printer has the lifespan limitation

such as pages per year. The lifespan means the average capacity of

print-outs, usually within the warranty period. For example, if the duty

cycle is 48,000 pages per month assuming 20 working days, a printer

limits 2,400 pages a day.

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.

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.
