What you are posting is still not specific enough -- nor is it a question. The whole topic is so huge that BOOKS have been written about it all.
So read widely among the search results linked above. Take good notes. If you still have questions (NOT the entire topic), be sure to ask them.
Also keep in mind that no one here will write your assignment for you.
