Web browser
A Web browser is a software program that enables you to view and
interact with various resources on the Web. An example of a widely used Web
browser is Microsoft Internet Explorer that displays both text and
graphics. Windows Internet Explorer 7 is available with Windows Vista.Some
browsers, such as Internet Explorer 7, offer a new feature called tabbed
browsing_ to facilitate better Web browsing. Using tabs, you can view
multiple Web sites in a single browser window and easily switch from one
Web site to another.Some Web sites may contain content in the form of
animation, video, or audio files. To view these files, you need additional
programs known as _add-ons_. An add-on is a software program that adds
features to your browser and enhances your Internet experience. Add-ons
provide added functions by allowing the Web browser to access and run files
that are included in Web pages. For example, Microsoft Silverlight is a
browser add-on that is required to view high-quality videos by using Web
browsers.

Web page
A Web page is a formatted text document on the Web that a Web browser
can display. Most Web pages on the Internet allow you to quickly move to
another Web page. You can do this by clicking a hyperlink, commonly called
a link_. Clicking a link opens the new Web page in your Web browser. You
can access existing Web pages or even create and publish new Web pages on
the Web.You can create Web pages by using a software language known as
Hypertext Markup Language (HTML). Web browsers use HTML to display Web
pages. Hypertext is a method of linking text with other text that helps you
to easily browse through related nonsequential topics on the same page or
on other Web pages.
