First off, you should try and amalgamate all your posts into one query, it doesn't clutter the board, and makes it easier to answer.. You've posted about five posts on various technologies with one line 'explain in detail'... one post would have been sufficient to ask all five questions..
that aside, this will answer all your queries
www.networkmagazine.com/static/tutorial/index.html
There is an in depth tutorial for just about every single technology you can think of.
