REVIEW CHAPTER 3

• The WWW is a collection of files that reside on computers located all over the world and that are connected to each other.
• HTML provides a variety of text-formatting tags that you can use to indicate headings, paragraphs, bulleted lists, and other useful text formats in Web documents.
• Hyperlinks usually connect to other Web pages, but they can also lead to graphic image files, sound clips, and video files.
• When you move the pointer over a(n) hyperlink, the pointer changes to indicate that if you click that text, the Web browser will open a Web page.
• "Server Busy" and "DNS entry not found" are common messages that indicate that your browser was unable to communicate successfully with the Web server that stores the page you requested.
• The term "home page" means the main page for a particular Web site, the first page that opens when you start your browser, and the Web page that a particular browser loads the first time you run it.
• Each part of an IP address is a number ranging from 0 to 255.
• The Telnet protocol is a set of rules for establishing a remote terminal connection to another computer.
• On most computers, the filename extension of an HTML document is .html or .htm.
• URLs follow the conventions established in the Unix operating system that use the forward slash character to separate the structure levels.
• The pathname describes the hierarchical directory or folder structure on the computer that stores the file.
• The FTP protocol is used to transfer files.
• The most common transfer protocol used on the Internet is HTTP.
• A Uniform Resource Locator is an addressing scheme that tells the Web browser the name of the file, the domain name of the computer on which the file resides, and what protocol to use when transporting the file.
• If you want to return to a Web page at a later date, you should store the URL in a bookmark file in the Navigator program for future use.
• Internet Explorer is Microsoft’s Web browser that installs with Windows 98.
• To save a graphic in Internet Explorer, right click it in the browser window, and click Save Picture As.
• Most web browsers display hyperlinks in a different color than other text and underline them so they are easily distinguished in the HTML document.
• Some Web sites are distributed over a number of locations, but most people who create Web sites store all of the site’s pages in one location, either on one computer or on one LAN.
• The 4.2 billion possible addresses in the Internet’s current addressing scheme are NOT sufficient to handle the Internet’s growing needs for the foreseeable future.
• No two computers on the Internet have the same domain name.
• The filename is the name that the computer uses to identify the Web page’s HTML document.
• Most windows programs use a standard graphical user interface design that includes a number of common screen elements.
• All web pages are NOT designed to resize automatically when loaded into different browser windows with different display areas, so a Web page will never be wider that your browser window.
• Web sites use encrypted transmission to send and receive information such as credit card numbers.
