In addition to standards for transfer and display of information, the Web introduced
the technology for hyperlinks to the Internet. A
hyperlink
(or
link
) is a node that provides
a user the ability to cross-reference information within a document or a Web page and to
move from one document or Web page to another.
Web Servers and Clients
The two general categories of computers involved in accessing Web pages are Web serv-
ers and Web clients. When you create a Web page or a Web site, you must post a copy
of your work to a Web server to share the page with the world. A
Web server
is a spe-
cialized server that stores and distributes information to computers that are connected to
the Internet.
A
Web client
(or
client
) is the computer an individual uses to access information, via
the Internet, that is stored on Web servers throughout the world. A home computer with
Internet access is considered a Web client. You must have access to the Internet to view
a Web site. Most people connect to the Internet through an Internet service provider. An
Internet service provider
(
ISP
) is a company that has direct access to the Internet and
sells access to other smaller entities. Some large institutions, such as universities, have
direct links to the Internet and are, in essence, their own ISPs.
In addition to being connected to the Internet, to view a Web site you must have a
Web browser installed on your client computer. A
Web browser
is the software that
interprets and displays Web pages. The Web browser enables users to view Web pages
from their client computer.
Two of the most common
Web browsers are
Microsoft Internet Explorer
and Mozilla Firefox.
