Home Pages and Web Browsers
The main page that all of the pages in a particular Web site are organized around and link
back to is called the site’s home page . The term “home page” is used in at least three dif-
ferent ways on the Web, and it is sometimes difficult to tell which meaning people intend
when they use the term. The first definition of home page indicates the main page for a
particular site; this use of “home page” refers to the first page that opens when you visit a
Web site. The second definition of home page is the first page that opens when you start
your Web browser. A Web browser is a software program used to retrieve and display
Web pages and to navigate them. You will learn more about Web browsers in the next
section. This type of home page might be an HTML document on your own computer.
Some people create such home pages and include hyperlinks to Web sites that they fre-
quently visit. The third definition of home page is the Web page that a particular Web
browser loads the first time you use it. This page usually is stored at the Web site of the
firm or organization that created the Web browser software. Home pages that fall within
the second or third definitions are sometimes called start pages .
To use your computer to gather information from the Internet and have access to the
HTML documents stored on the Web, your computer needs to have a Web browser
installed on it. As stated earlier, Web browser software is designed to access, retrieve, and
display Web pages on your computer. Although the Internet connects many different types
of computers running different operating system software, Web browser software lets your
computer communicate with all of these different types of computers easily and effec-
tively. Two popular browsers are Microsoft Internet Explorer, or simply Internet Explorer,
and Netscape Navigator, or simply Navigator.
In addition to Web browser software, you also need a means of connecting to the
Internet. If you are a student at a university, you might be connected to the Internet
through the university’s computer network. If you use a computer from your home, you
might have a connection to the Internet through your phone line and a modem. This is
called a dial-up connection . Another connection option for home-based Internet users is a
DSL (Digital Subscriber Line) connection , which uses your phone line to establish a high-
speed connection. Home connections require an account with an Internet service
provider (ISP) , a company that sells Internet access. This company guides you in configur-
ing your computer to connect to one of its servers via a telephone or cable modem. When
you are logged on to your ISP account, meaning you are connected to your ISP’s server,
you can use the browser software on your computer to access files and other resources
located anywhere on the Internet.
