In object-oriented programming, an object is a self-contained entity that consists of both data and manipulation procedures.
Similarly, HTML 4.0 includes the <OBJECT> element to extend HTML in order to make it more dynamic. <OBJECT> allows an author to download external data or programs into the current page. This element can be used to gather other pieces of information, including Java applets, ActiveX controls, and possibly dHTML. The long-term goal of the World Wide Web Consortium (W3C) is for the <OBJECT> element to become the only way to embed data, replacing the <APPLET> and <IMG> elements.
A peer-to-peer (P2P) network is one where each workstation has both server and client capabilities and users can initiate communication between any two (or more) computers.

With the advent of file-exchange programs like Napster, peer-to-peer has also come to describe the exchange of files through a mediating server.
The word template comes from a woodworking term meaning a thin sheet of metal with shapes cut out of it as a guide. Similarly, HTML templates are skeletal HTML pages with the main content left out.

When creating templates, it’s always a good idea to use of a lot of comments (explanatory text within
<!-- these tags -->
) so others will be able to use them without much trouble.
