Website and Internet Know How Needed - When and why do websites use "www"?


When I link to my own photos here, I always want to put http://www but the www doesn't belong. When and also why is "www" needed? I know the "https" is a secure site. Can someone concisely explain www http and https and any others?

    That's 100% wrong. It is part of an URL, but not a required part.
