Hacker: Commonly used to refer to any individual who uses their knowledge of networks and computer systems to gain unauthorized access to computer systems. While often used interchangeably, the term hacker typically applies to those who break in out of curiosity or for the challenge itself rather than those who actually intend to steal or damage data. Hacker purists claim that true hacking is benign and that the term is misused.
Heuristic: Heuristics uses past experience to make educated guesses about the present. Using rules and decisions based on analysis of past network or email traffic, heuristic scanning in antivirus software can self-learn and use artificial intelligence to attempt to block viruses or worms that are not yet known about and for which the antivirus software does not yet have a filter to detect or block.

Honeypot: A honeypot is a computer system intended to attract or lure attackers to it. A honeypot serves to distract attackers from the real targets as a decoy as well as a means to track and monitor attacks to learn from them in order to develop better protection for the real systems.
Host: As far as the Internet is concerned a Host is essentially any computer connected to the Internet. Each computer or device has a unique IP address which helps other devices on the Internet find and communicate with that Host.
HTML: HTML (Hypertext Markup Language) is the basic language used to create graphic web pages. HTML defines the syntax and tags used to create documents on the World Wide Web. In its basic form, HTML documents are static- meaning they display text and graphics but that is all. In order to have scrolling text, animations, buttons that change when the mouse pointer is over them, etc. a developer needs to use active scripting like JavaScript or VBScript or use 3rd party plug-ins like Macromedia Flash.
There are variations and additions to HTML as well. DHTML (Dynamic Hypertext Markup Language) is used to refer to pages that include things like JavaScript or CGI scripts in order to dynamically present information unique to each user or each time the user visits the site. XML (Extensible Markup Language) is gaining in popularity because of its ability to interact with data and provide a means for sharing and interpreting data between different platforms and applications.
