    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?

    WWW: Meaning world wide web, must be included in any URL.

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

    Not only is the www not always needed, Google at least will treat www.url.com and url.com as 2 different sites. In webmaster tools you can set which one is the default for your websites. For example, I don't have the www on any of my blogs. The address of one, for example, is only http://thefriendlypitbull.com/. If you go to www.thefriendlypitbull.com, it will remove the www.

    The internet relies on different protocols to transfer data in different forms.

    You mentioned two of them - HTTP and HTTPS. HTTP is Hypertext Transfer Protocol, and it indicates that the data is intended to be opened and displayed in a web browser. The "S" in HTTPS indicates that the given data is being transferred securely.

    FTP is File Transfer Protocol. This protocol indicates that the data being transferred is a file (perhaps an executable file or a large data file) that should be downloaded instead of opened and rendered in a browser.

    SMTP stands for Simple Mail Transfer Protocol, and it is used to send outgoing mail. POP stands for Post Office Protocol, and it is used to retrieve mail from a mail server.

    The "www" that is prepended to a web address is simply a deprecated way of indicating that a given web address points to a webpage that should be downloaded via HTTP. Now it operates as a subdomain, so technically www.hubpages.com is a sub-domain of hubpages, just like brianrock.hubpages.com. However, most webservers are set up to redirect addresses with the "www" to an address without it.
