http means that we are using the server for accessing HTML files - normal web browsing. We can also use other protocols like ftp (used for transferring files), smtp (outgoing email), imap(incoming email), etc. Sure, when we're using a web browser we can usually assume that it's http (or https) but this is not always the case. As for the 'www.', typically we just redirect the 'http://www.hubski.com address to 'http://hubski.com (or vice versa), but we don't have to. You could make the addresses point to different websites - although why you would want to do that is a mystery to me. BTW, having a leading / such as in "/hubski.com" will often make the browser think you're looking up a file.
