Internet Terminology Study Sheet

Internet: A worldwide system of computer networks - a network of networks in which users at any one computer can, if they have permission, get information from any other computer

An Internet Protocol address or IP address is a unique computer (host) location on the Internet (expressed either as a unique string of numbers or as its associated URL).
Examples:Unique number string: 64.233.167.99 (Google) or 216.64.210.28 (Coke)     

Domain Name:  A domain name locates an organization or other entity on the Internet.   A domain name is associated with an IP address.  For example, mountaindiscovery.org is linked to 68.178.254.180.  This is a shared IP address, so more than one URL resolves to this IP address. 

URL (Uniform Resource Locator):  The unique address for a file on the internet.  For example, www.solarisnetwork.com/glossary is the URL that directs a web browser to the online glossary for a theatre lighting supply company.  Enter the URL into the address bar of a web browser and see for yourself.

Web Browser:  A software program that allows a user to look at and interact with all of the information on the internet.  Examples: Microsoft Internet Explorer, Netscape, Mozilla Firefox.

Hyperlink: A link embedded in the text of a web page or other file that a user can click and navigate to the file or web page.  A hyperlink is frequently highlighted and/or underlined.
