URL (Uniform Resource Locator) - The address that defines the route to a file on the Web or any other Internet facility. URLs are typed into the browser to access Web pages, and URLs are embedded within the pages themselves to pro- vide the hypertext links to other pages.

UTP - Unshielded twisted pair is the most common kind of copper telephone wiring. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electro- magnetic induction between pairs of wires, two insulated copper wires are twist- ed around each other. Each signal on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable.

VLAN (Virtual LAN) - A logical association that allows users to communicate as if they were physically connected to a single LAN, independent of the actual physical configuration of the network.

Virtual Server - Multiple servers that appear as one server, or one system image, to the operating system or for network administration.

Wake-on-LAN- Wake on LAN is a technology that allows a network profes- sional to remotely power on a computer or to wake it up from sleep mode.

WAN - A communications network that covers a wide geographic area, such as a state or country.

WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64- bit shared key algorithm, as described in the IEEE 802.11 standard.

WINIPCFG - Configuration utility based on the Win32 API for querying, defining, and managing IP addresses within a network. A commonly used util- ity for configuring networks with static IP addresses.

Workgroup - Two or more individuals that share files and databases.

Appendix C: How to Ping Your ISP’s E-mail & Web Addresses

Virtually all Internet addresses are configured with words or characters (e.g., www.linksys.com, www.yahoo.com, etc.) In actuality, however, these Internet addresses are assigned to IP addresses, which are the true addresses on the Internet. For example, www.linksys.com is actually 216.23.162.142. Type it into your web browser and you will wind up at the Linksys home page every time. There are servers that translate the URL to an IP address; this is called Domain Name System (DNS).

IP and web addresses, however, can sometimes be long and hard to remember. Because of this, certain ISPs will shorten their server addresses to single words or codes on their users’ web browser or e-mail configurations. If your ISP’s e- mail and web server addresses are configured with single words (www, e-mail, home, pop3, etc.) rather than whole Internet addresses or IP addresses, the Router may have problems sending or receiving mail and accessing the Internet. This happens because the Router has not been configured by your ISP to accept their abbreviated server addresses.

The solution is to determine the true web addresses behind your ISPs code words. You can determine the IP and web addresses of your ISP’s servers by “pinging” them.

Important: If you don’t have your ISP’s web and e-mail IP addresses, you must either get them from your ISP or follow these steps prior to connecting your Cable/DSL Router to your network.
