C-1Appendix C Description of Terms10BASE-TAn Ethernet interface having a bandwidth, which provides a transmissionrate, that may go up to 10 Mbps using a Category 5 cable.ATU-C (ADSL Transceiver-Central Office)A central unit managed by an ISP(Internet Service Provider) forconnection of ADSL subscriber lines.ATU-R (ADSL Transceiver -Remote Terminal)A subscriber terminal which is connected to ATU-C through a telephoneline, which processes ADSL service.ADSL (Asymmetric Digital Subscriber Line)A device providing a high-speed data interface to the Internet, and otherservices, through a telephone network. This does not influence existingtelephone service. Data downloading rate can vary depending ontransmission distance, ATU-C, and subscribing services. Data downloadingrate is from 640Kbps to 8Mbps, and uploading rate is from 16Kbps to800Kbps.ATM (Asynchronous Transfer Mode)One of the communications transfer modes. A control mode in which aseries of terminals can simultaneously send data while a terminal issending data, thereby allowing a series of terminals to share a singletransmission line for communication.

C-2Appendix CDescription of TermsBridgeA functional unit interconnecting two or more local area networks (LANs)that uses the same link protocol. The bridge not only transmits but alsofilters packets. The bridge usually operates on a Data Link Layer when ittransmits packets.DMT (Discrete Multi-Tone)A modulation technique of segmenting and transmitting a large amount ofdata by way of Multi-carrier, in which a carrier frequency band ismultiplexed, thereby realizing optimal performance on a Loop.EthernetA representative method of interconnecting LANs was using atransmission cable of 10BASE standard. Three companies, i.e., Xerox, Inteland DEC develop this method, in cooperation. Its transmission rate isabout 10 Mbps, and employs a CSMA/CD access method in which a nodemonitors signals over a transmission line and sends data after confirmingthat the other nodes do not send signals.HubA communications interface used for interconnecting a series of devices ona network. This retransmits a signal, which is received from a device, orsegments a received signal and transmits the segmented signal.FTP (File Transfer Protocol)A protocol for transferring files from one host to another or from a host to apersonal computer over a network.

C-3GopherAn interface that has been used as the easiest interface before the WWWservice was developed. The gopher constructs a menu by classifying thecontents of information by topic or type, thereby allowing even people,whom is not familiar with the Internet, to easily search information. Inaddition, other functions of the Internet such as remote access, file transfer,news, etc. can be performed in the gopher menu. A series of gopherservers are interconnected so that a user can search for desiredinformation moving from one gopher server to another.IP (Internet Protocol) AddressAn address of a host or a device on the Internet. It is composed of 4 bytes.Each byte is divided by a period. An IP address is assigned by IANA(Internet Assigned Numbers Authority) to avoid duplication.PPPoA (Point-to-Point Protocol)The standard protocol for providing the serial interface between nodes, e.g.,between a PC and a RAS or between routers, on the Internet. PPPoAprovides an Internet access rate, and is widely used substituting for a SLIP(Serial Line Internet Protocol) which is a previously used serial interfaceprotocol.
