• When using your Internet connection to become part of the Web, your computer becomes a Web client.
• The software you use to connect your computer to the Web server is your Web browser. – Common Web browsers are Navigator and Internet Explorer – These browsers use a standard Graphical User Interface design

Anchor tags are used to define hyperlinks
• Text files on Web servers are coded with HTML formatting tags that enable your browser to read text.
• The tag that gives HTML its power, however, is the anchor tag.
• Each anchor tag used in an HTML document, or Web page, creates a hypertext link or hypermedia link to other HTML documents or to other media.
• These links are a different color than other text on the page, and are sometimes underlined. When you click the link, you connect to another Web page.

Learn about Web addresses and URLs
• Each computer on the Internet has an unique identification number, called an IP (Internet Protocol) address.
• The IP addressing system currently in use on the Internet uses a four-part number.
• Each part of the address is a number ranging from 0 to 255, and each part is separated from the previous part by a period, for example: 106.29.242.17.
• Although each computer connected to the Internet has a unique IP address, most Web browsers use domain name addressing to locate Web sites and pages.
