Yes, there is an interesting and subtle nuance here. In the way our WikiAnswers lingo has evolved, supervising a Topic means watching a topic section for spam and vandalism. It might also mean doing the basic editing of new questions, such as correcting extremely badly-worded questions (e.g. changing "XYZ am I pregnent please?" to "What are chances of being pregnant if XYZ?"). Wikianswers Supervisors play an extremely important role. They keep the farm from becoming a jungle. Wikianswers Contributors actually work on growing questions and answers. There are lots of ways to contribute to Wikianswers. It can simply mean asking and answering questions. More deeply, it can mean developing questions and answers into topics, e.g. by making personal questions and answers more generic or universal, moving questions to the right topics, adding alternate versions of questions, linking questions together, etc. The lines between these two functions aren't strict, of course. Most of us do both. The previous technical response is certainly proper. But another observed difference is: The occasional contributor of questions &/or answers is a well balanced, concerned individual. Those that get hooked and stalk the site, becoming frequent contributors are nuts, (sometimes crossing the line to crazy). Those that do all that and then doggedly work so it all makes sense, operates well...they are certifiable masochistic lunatics!
A brain.
Google search - is a search engine. WikiAnswers is a forum.
Spamming is a type of vandalism, but not all vandalism is spam.
There is no difference. For a while, Wikianswers was the main display site. However, Answers decided to bring it all under the Answers.com brand, since it is all Answers.com content.
WikiAnswers it not a search engine, it is an online Q&A website. A search engine provides links to other websites; WikiAnswers and Answers.com aims to answer your questions directly, through a Wiki-based system.
The search engine is more detailed and expansive as compared to WikiAnswers when it comes to finding answers for homework questions.
Vandalism is considered abusing your privileges as a contributor which includes using WA as a place for communication between friends on your message boards, asking inappropriate questions, answering with inappropriate questions (this includes sexual, offensive, and sarcasm), asking/answering questions about illegal activities etc. Basically anything that would lower the quality of the site from contributions, that user can be blocked or banned from Wikianswers by a Supervisor. You can view the Stylebook ( http://wiki.answers.com/Q/What_are_the_WikiAnswers_style_rules) for appropriate conduct as WA contributor!

Supervising mode is what system kernel runs in. It has unrestricted access to hardware, processor, memory and everything else. User mode is managed by supervisor mode, so programs can't crash other programs deliberately by writing over their memory. User mode programs communicate with hardware and kernel itself by system calls.
