Appendix B: GLOSSARY Ethernet One of the most common Local Area Network (LAN) protocols. Ethernet uses a bus topology that supports a data transfer rate of 10Mbps. Fast Ethernet Much the same as Ethernet but 10 times faster; requires upgraded network cards and hubs. Protocol A protocol is a set of rules for communicating between computers. 10Base-T A variant of Ethernet that allows computers to be networked at 10Mbps via twisted pair cable.
PPPoE supports reliable and straightforward end-user authentication with no security risk and can provide a range of operational benefits to both the subscriber as well as the service provider. Among these are network management and diagnostic capabilities that can identify operational problems and automatically offer resolutions. Firewall A security system used to enforce an access control policy between a LAN and the Internet. Gateway A device that links two different networks.
TCP/IP protocols are used for Internet communications and consist of: TCP (Transmission Control Protocol), which uses a set of rules to exchange messages with other Internet points IP (Internet Protocol), which uses a set of rules to identify Internet addresses on the Internet. Every computer on the Internet has a unique IP address.
