Glossary
This glossary provides definitions of some common Internet terms.
active content
Material on a Web page that changes with time or
in response to user action. Active content is
implemented through ActiveX controls, Visual
Basic Scripts, Java scripts, and Java applets in the
HTML code that defines the page.
ActiveX control
A program that runs within a browser using
Microsoft technology to add life to a Web page by
using animation, streaming audio and video,
movies, and so on. When you visit a Web page that
contains an ActiveX control, it is dynamically
downloaded and saved to your hard disk. Unlike
Java applets, ActiveX controls don’t run in a
restricted environment, and have the potential to
take control of your computer.
alert
A dialog box that appears in a graphical user
interface (GUI) to signal that an error has
occurred, or to provide a warning.
banner ad
An advertising graphic, often animated, that
appears on a Web page and may contain a link to
the advertiser’s Web site.
browser
A software application that makes navigating the
Internet easy by providing a graphical user
interface. This lets the user click menus, icons, or
buttons rather than learn difficult computer
commands. Also called a Web client.
