71 _GlossaryAn emulator duplicates the functions of one system with a differentsystem, so that the second system behaves like the first system.Emulation focuses on exact reproduction of external behavior, which isin contrast to simulation, which concerns an abstract model of thesystem being simulated, often considering its internal state.EthernetEthernet is a frame-based computer networking technology for localarea networks (LANs). It defines wiring and signaling for the physicallayer, and frame formats and protocols for the media access control(MAC)/data link layer of the OSI model. Ethernet is mostly standardizedas IEEE 802.3. It has become the most widespread LAN technology inuse during the 1990s to the present.EtherTalkA suite of protocols developed by Apple Computer for computernetworking. It was included in the original Macintosh (1984) and is nowdeprecated by Apple in favor of TCP/IP networking.FDIForeign Device Interface (FDI) is a card installed inside the machine toallow a third party device such as a coin operated device or a cardreader. Those devices allow the pay-for-print service on your machine.FTPA File Transfer Protocol (FTP) is a commonly used protocol forexchanging files over any network that supports the TCP/IP protocol(such as the Internet or an intranet).Fuser UnitThe part of a laser printer that melts the toner onto the print media. Itconsists of a hot roller and a back-up roller. After toner is transferredonto the paper, the fuser unit applies heat and pressure to ensure thatthe toner stays on the paper permanently, which is why paper is warmwhen it comes out of a laser printer.GatewayA connection between computer networks, or between a computernetwork and a telephone line. It is very popular, as it is a computer or anetwork that allows access to another computer or network.GrayscaleA shades of gray that represent light and dark portions of an imagewhen color images are converted to grayscale; colors are representedby various shades of gray.HalftoneAn image type that simulates grayscale by varying the number of dots.Highly colored areas consist of a large number of dots, while lighterareas consist of a smaller number of dots.HDDHard Disk Drive (HDD), commonly referred to as a hard drive or harddisk, is a non-volatile storage device which stores digitally-encoded dataon rapidly rotating platters with magnetic surfaces.IEEEThe Institute of Electrical and Electronics Engineers (IEEE) is aninternational non-profit, professional organization for the advancementof technology related to electricity.IEEE 1284The 1284 parallel port standard was developed by the Institute ofElectrical and Electronics Engineers (IEEE). The term "1284-B" refers toa specific connector type on the end of the parallel cable that attaches tothe peripheral (for example, a printer).IntranetA private network that uses Internet Protocols, network connectivity, andpossibly the public telecommunication system to securely share part ofan organization's information or operations with its employees.Sometimes the term refers only to the most visible service, the internalwebsite.IP addressAn Internet Protocol (IP) address is a unique number that devices use inorder to identify and communicate with each other on a network utilizingthe Internet Protocol standard.IPMThe Images Per Minute (IPM) is a way of measuring the speed of aprinter. An IPM rate indicates the number of single-sided sheets a printercan complete within one minute.IPPThe Internet Printing Protocol (IPP) defines a standard protocol forprinting as well as managing print jobs, media size, resolution, and soforth. IPP can be used locally or over the Internet to hundreds ofprinters, and also supports access control, authentication, andencryption, making it a much more capable and secure printing solutionthan older ones.IPX/SPXIPX/SPX stands for Internet Packet Exchange/Sequenced PacketExchange. It is a networking protocol used by the Novell NetWareoperating systems. IPX and SPX both provide connection servicessimilar to TCP/IP, with the IPX protocol having similarities to IP, andSPX having similarities to TCP. IPX/SPX was primarily designed forlocal area networks (LANs), and is a very efficient protocol for thispurpose (typically its performance exceeds that of TCP/IP on a LAN).ISOThe International Organization for Standardization (ISO) is aninternational standard-setting body composed of representatives fromnational standards bodies. It produces world-wide industrial andcommercial standards.ITU-TThe International Telecommunication Union is an internationalorganization established to standardize and regulate international radioand telecommunications. Its main tasks include standardization,allocation of the radio spectrum, and organizing interconnectionarrangements between different countries to allow international phonecalls. A -T out of ITU-T indicates telecommunication.ITU-T No. 1 chartStandardized test chart published by ITU-T for document facsimiletransmissions.JBIGJoint Bi-level Image Experts Group (JBIG) is an image compressionstandard with no loss of accuracy or quality, which was designed forcompression of binary images, particularly for faxes, but can also beused on other images.JPEGJoint Photographic Experts Group (JPEG) is a most commonly usedstandard method of lossy compression for photographic images. It is theformat used for storing and transmitting photographs on the World WideWeb.LDAPThe Lightweight Directory Access Protocol (LDAP) is a networkingprotocol for querying and modifying directory services running over TCP/IP.
