At a very basic level every website is just a bunch of files. And as everyone knows you need a computer to store files on (ok - technically you can store files on memory sticks, DVD's and the like but bear with me on this). Right. Where was I?
Yes - the web server is effectively just a computer that is configured in a specific way to allow others to access it across the net. So when you buy a web hosting package you are buying space on a web server.
We like to keep things as simple as possible so we offer a one-size-fits-all package that includes emails, databases and loads more.
Of course there are other options available like standalone servers - if you need any more info then just get in touch.
