BROWSERS

Browsers connect to Web sites and display Web pages.

A browser helps you connect to the web, open and transfer files, and display text and images. The two most widely used browser programs are Microsoft’s Internet Explorer and Mozilla Firefox.

FEATURES

To connect to other resources, the location, or address, called uniform resource locators (URLs) or simply Web site addresses must be specified. Once connected to a Web site, a document file containing Hypertext Markup Language (HTML) commands is sent to your computer. The browser interprets the HTML commands and displays the document as a Web page. The first page, referred to as the home page, presents information about the site references and hyperlinks, or connections to other documents.

CASE

Assume that you have accepted a job as advertising coordinator for Adventure Travel Tours. Your supervisor has asked you to review the company Web site, to locate travel information on Peru, and to communicate your findings to her. See Figures 1 through 3.

Web Page

An HTML document sent to your computer and displayed by a browser is a Web page (see figure 1).

Web Site Address

Each Web page has its own Web site address, called the Uniform Resource Locator (URL), which provides location information used to navigate through the Internet to access a page. (see figure 1)

Hypertext Link

A hypertext link, also called a hyperlink or simply a link, is a connection to another Web page or to another location on the current page (see figure 1).

NAVIGATING

After your browser connects to the Web, you begin navigating by entering the Web address for Adventure Travel Tours and connecting to that site. The company’s Web page appears on your display. You begin your evaluation by exploring the site and its hypertext links (see figure 1). Search service

Search Services are Web sites that maintain and provide access to huge databases of Web pages and Internet sites (see figure 2).

Topic Search

A topic search is conducted by selecting a category and then continuing to select subcategories until your search has been narrowed and a list of relevant documents appears (see figure 2). Keyword Search

A keyword search is conducted by entering a specific word or words into a text box, then searching through a list of resulting Web sites that contain the word or words (see figure 2).

SEARCHING

After reviewing the company site, you begin your search for information on Peru. Using the Search button, you connect to Yahoo!, a well-known search service. After conducting a topic search and a keyword search, you locate a site that provides just the information you are looking for (see figure 2). E-Mail Address

On the Internet, each person has a unique e-mail address or means of identification (see figure 3).

Attachment

An attachment is a file that is included with an e-mail message (see figure 3). New Message Window

The new message window is a part of Microsoft Outlook Express and is used to create e-mail messages (see figure 3).

COMMUNICATING

To share the Peru site with your supervisor, you choose File/Send/Link By E-Mail from the browser’s menu bar. An e-mail new message window opens with a hyperlink to the Peru site and an attachment containing the HTML document. All you need to do is enter your supervisor’s e-mail address, type your note, and send it (see figure 3).
