The difference between a domain name and a website name

The name of the site is equivalent to the land and land of the building, on this land you can build any number of buildings.

Give me a chestnut:

baidu.com//Domain name

http://news.baidu.com///Website name consists of server name + domain name; HTTP is the transport protocol

http://map.baidu.com/Baidu Map

http://music.baidu.com/Baidu Music

http://wenku.baidu.com/Baidu Library

Domain name is very important, if you want to choose another host agent, there is a domain name can be updated to the new host agent.
