This document discusses how computers connect to the internet using IP addresses made up of four numbers between 0-255 separated by periods. While computers use IP addresses, web browsers typically use domain names to locate websites and pages. The document also mentions that HTML files use tags like anchor tags to create hyperlinks between web pages, and these links are usually a different color and sometimes underlined to indicate they can be clicked to access another 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.

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.
