List the steps involved in retrieving a Web page from a server Use a chart like the one below (also available online)
The Web is probably the Internet s most widely used component As you learned, the Web uses HTTP (Hypertext Transfer Protocol), which allows pages to be interlinked This interlinking lets users move easily from page to page It is this ability to browse through pages that sets the Web apart from other Internet components, such as FTP sites and newsgroups
Uniform Resource Locators (URLs)
How do URLs work with browsers
Every Web page has a unique address known as a uniform resource locator or URL Like IP addresses, URLs enable a browser to locate specific page files on the Web
URL Components
HTTP requires Web page URLs to be in a standard format that browsers know how to interpret Most URLs consist of four main parts: protocol://address/directory path/retrieved file The protocol indicates the type of server where the file is stored The address is the server s address The directory path is the file s location within the file structure of that particular server The retrieved file is the name of the specific Web page file being accessed Together, these four components form a URL that specifies a single page on the Web Each Web page in a site has its own address, just like every page in a book has its own page number

Figure 34 shows the URL for the corporate history page on the McGraw-Hill Web site: http://wwwmcgraw-hillcom/about/historyhtml The http specifies that this page is stored on an HTTP, or Web, server The address ( wwwmcgraw-hillcom ) is the Web server s address The www indicates that the server is part of the World Wide Web The mcgraw-hillcom is the site s domain name A domain name identifies the entity (such as a university, individual, or business) that sponsors the site This URL tells users that McGraw-Hill owns the site The about tells users the directory path they need to follow to find a specific page The historyhtml is the name of the file that contains the Web page the user is viewing The html indicates that this page is written in HTML code
World Wide Web Domain name extension
Each component of a URL has a specific meaning How can you tell that this URL specifies a file on the World Wide Web
Protocol
http://wwwmcgraw-hillcom/about/historyhtml
Domain name Directory path Retrieved file
Domain Name Extensions
A domain name typically ends with a dot followed by letters These letters identify the URL s domain name extension A domain name extension tells users what type of organization uses the address For example, the extension com in the McGraw-Hill URL indicates that this is a commercial site Table 32 lists some commonly used domain name extensions
Table 32
URLs contain domain name extensions What information can you learn from a domain name extension
Common Domain Name Extensions
Extension com edu gov org mil net biz info Description of Site Commercial or for-profit business Educational site US government organization Professional or nonprofit organization Military site Network site Commercial business Information site Example wwwdellcom wwwharvardedu wwwfirstgovgov wwwredcrossorg wwwarmymil http://eelinknet wwwdgmibiz wwweclipsesinfo

Using a Web Browser
How is a Web browser essential to viewing Web pages
You need a Web browser to request, retrieve, and view Web pages A browser is a software application that you can install and customize
Platform Differences
Not all Web browsers interpret and display HTML identically Some common browser issues include the following Design Issues Margin spacing around the edges of a page often varies in different browsers Text may wrap at different places Font sizes and colors may vary, as may the appearance of hyperlinks Browser Restrictions Not every browser will support all of the features that you may want to use in your Web pages Also, some older operating systems may not be able to run newer browsers Browsers and Accessibility Many browsers include accessibility options An accessibility option is a feature that allows differently abled individuals to access and use Web pages For example, most browsers let users increase the size of text on the screen This option helps users with impaired vision read text more easily
Design Since pages may look different in different browsers, think about what type of browsers your audience may be using when you design your pages
