To create multiple websites with same domain name.

I want to ask is it possible to create multiple websites with the same domain name ? If possible, how can I do the same....
Does anybody knows regarding this, please help.....

thank you

When you buy a domain name of your own, you can do a lot of things..
For example, if you own a domain like "google.com" (which you can't, since someone has already bought it), you can make "gmail.google.com" point to a different website from (say) "www.google.com". These names, "gmail.google.com" and "www.google.com", are just subdomains of the main "google.com". That is, once you own the main domain, like google.com, you can add any number of subdomains you want, and have them point to different websites.
Alternatively, you can also have them point to the same website if that's what you prefer.
For example, both mywebsite.com and www.mywebsite.com point to the same website.

To make subdomains on your website, you will need the cooperation of your web host. A web host is simply the company that owns the computer where you place your website.
You need a web host because your own computer isn't permanently connected to the Internet. Even if it is (eg, because you never turn off your computer), your broadband provider will usually not allow you to host a website using that connection.
There are also a number of other complications involved, so it's simplest to think of a web host as a necessity if you want to create your own website.

Many commercial web hosts will let you create subdomains and associate them with a new website (or the same website). This may or may not involve the payment of a additional fee per subdomain; it varies from web host to web host. However, you do not have to "buy" a subdomain; once you own the main domain, all its subdomains belong to you.

It is also possible to avoid using sub-domains entirely and still create multiple websites on a single domain.
For example, if you own a domain like "example.com", and you want each member of your family to have their own website on that domain, you can have each person create his/her website and place it in its own folder.
So, for example, Tom may have his website in "www.example.com/tom/" while Dick has his in "www.example.com/dick/", and Harry in "www.example.com/harry/".
You can create any number of folders this way, each associated with a different website.
