Glossary
Frame
The basic unit of Ethernet data traffic. An Ethernet frame can vary in size from a minimum length of 64 bytes to a maximum length of 1522 bytes. An Ethernet frame contains the Ethernet destination address, Ethernet source address, 802.1Q/1p fields, and TCP/IP packet.
Gigabit Ethernet
An extension of the Ethernet standard, offering speeds of 1 Gbps. That equals 1,000 Mbps
Hub
A device that interconnects clients and servers, simply repeating or amplifying the signals between them. Hubs act as wiring “concentrators” in networks based on star topologies, rather than bus topologies, in which computers are

Internet
A massive global network, interconnecting countless computers and networks worldwide. It is accessible from any computer with a modem or router connection and the appropriate software.
IP
Internet Protocol. A network layer protocol in the TCP/IP stack offering a connec- tionless internetwork service. IP provides features for addressing,
IP Routing
Unlike static routing, where traffic patterns are established by the network admin- istrator and must be manually adjusted, IP routing is dynamic. When a packet begins its journey through the network, its entire route is not known. Instead,
it progresses through the network one “hop” at a time, and at each interval the network automatically calculates the ideal route to the next stop along the way. This improves network performance and availability.
IP Telephony
The transmission of voice and fax telephone calls over data networks using the Internet Protocol.
IP Video
The transmission of video images over data networks using the Internet Protocol.
