It normally relates to a different address being used to retrieve data (not the main www address) .  See below for more information

There is no functional difference.  

They all use HTTP protocol to send and receive data.

It is just a different subdomain on the main domain.  It can be anything they wish.   Many people will do this during site migrations for testing and such and some never update their www. domains back.

Here is the HTTP Specifications that are used for data transmissions for even further reading.

Some browser automatically adds www and you can use CTRL+ENTER to automatically add www. prefix and .com suffix. www1 as the main URL just alienates users in my opinion. It is much easier to just rewrite or redirect URLs

Some websites don't use www (Example: https://slashdot.org).  From a technical point of view you can put nothing or anything you want before the domain name.


Open in new window

Most of the websites I've visited are configured to use www but it's not mandatory, more of an internet convention.
