As others have said, it's theoretically possible to have http://www.domain.com and http://domain.com return different sites, but that would be horrible from a user point of view (no-one would expect that, and it would just confuse them).

You should pick one form (with or without www) and stick with it, and have the other do a "301 redirect" to it. So if you want to omit the "www", then "http://www.domain.com" should 301-redirect to "http://domain.com".

This avoids duplicate copies of the page being recorded by search engines (i.e. one with and one without the www in the address). If you are only making the change after many pages have *already* been indexed from the alternate address, you probably want to redirect to the same page, e.g.:-

http://www.domain.com/subfolder/blah.htm

should 301-redirect to

http://domain.com/subfolder/blah.htm

Ditto if you have another domain you want to redirect to domain.com.

Never have the same content directly returned from more than one domain, else you have the risk of it being seen as duplicate content (even though it isn't from your point of view). The user can still type in the alternate form, but should get the page via a 301-redirect.

Sorry, I can't give technical details on how to set up the 301 redirect.

I have all along wondered the need to prefix URLs with these three w's. I feel validated that there is an entire group out there which has been thinking along the same lines.

There is a big difference. Some sites do not solve this problem. If you go to www.domain.com and domain.com will have examples of their land on different pages. Advice, you must declare and fix your www determination. This can also help to have a better search engine optimization results.

http://www.xyz.com is the same as http://xyz.com on most web servers. i.e. one can reach the site with or without the www in front. What some web hosting companies don't get is that this creates a SEO problem - duplicate content. One needs to select which version of the url they are going to promote and 301 permanent redirect the other one to it.

There is no difference on registering with domain, because register need only yourdomain along with .extension, i.e., for example: yourdomain.com. www is just considered as a subdomain for main domain where it should be added in a dns for every hosting account by hosting providers.

What is the difference

What is the difference between local server and global server? Can we use the same data base for storing data in both the servers?

www stands for world wide web

www stands for world wide web it was created because they think that they will create other systems for example (just example) let say ggg. You register name of domain with extension www is always there. You can chose to dont use so.

If you are doing link building then you should vary these things for better result as Google would think that you are doing the work manually..
