Xerox and formalized in 1980 by DEC, Intel, and Xerox. Ethernet networks transmit data at 10/100 Mbps using a specified
protocol.
Ethernet Address (MAC Address):
An Ethernet address is a unique, pre-programmed address, sometimes referred to as a media access control (MAC) address.
Each computer on an Ethernet network has its own Ethernet address. This 12-digit hexadecimal address is encoded into the
circuitry of the computer's network adapter when it is manufactured. Other devices on the network use this address to identify
the computer. This address is not the same as the
IP address
that is assigned to computers on
TCP/IP
networks. On these
networks, the IP address is associated with the MAC address to enable network communication.
Host:
A host is any device that is connected to the network, for example, a computer, network printer, or router. Each host has a
unique name (called "Host Name") or IP address (called "Host IP") for identifying on the network.
Internet Protocol (IP):
IP is the protocol used to send data from one computer to another over the Internet. The IP protocol describes how Internet
computers keep track of the
IP address
of each computer on the network and route packets of data from one IP address to
another.
Internet Service Provider (ISP):
An ISP is a company that provides individuals and other companies access to the Internet and other related services such as
website building and virtual hosting. An ISP has the equipment and the telecommunication line access required to have POP on
the Internet for the geographic area served. The larger ISPs have their own high-speed leased lines so that they are less
dependent on the telecommunication providers and can provide better service to their customers.
IP Address:
An IP address provides unique identification for each computer on the Internet or on a local network. IP addresses are usually
expressed as a group of four numbers separated by periods, for example, 169.254.10.2. None of the numbers can be greater
than 255. Each Ethernet interface has an IP address. For the Dell TrueMobile 2300 Wireless Broadband Router, there is a
LAN
Ethernet interface and a
WAN
Ethernet interface; hence, there is a LAN IP address and a WAN IP address.
Link Light:
A link light is a light on a network device that indicates a good network connection. Hubs typically have a link light for each
port; although, they may not be labeled as such, and the lights may show other information. These lights often blink for network
activity. Some hubs display different colored lights for 10 Mbps and 100 Mbps. For more information, see the documentation
accompanying your product.
Local Area Network (LAN):
A LAN is a network in one location. The network lets users at that location share files, printers and other services.
See WAN.
