A website is a collection of files. In order to be accessible by everyone at anytime, these files need to be stored on a computer connected to the Internet on a permanent basis. This computer is called a server.

The more a website attracts visitors, the more the server/computer needs to be powerful and needs to have a high speed connection. Some websites which were initially hosted by private computers switch to professional hosts once the site becomes popular.

Whenever a site gets a new host, in no case its users will be aware of the change. The address (www) does not refer to the server, it refers to the owner of the site. The owner can change the physical address of their servers. All they have to do is to change the link the address refers to and their visitors will be sent to the right site.
