    How Does Web Browsing Work?
   The Process of Using a “Browser”
       You type the URL of a requested Web
        page such as www.yahoo.com.
       A message is sent to a Domain Name
        Server (DNS) which returns the “IP”
        address (e.g., 68.142.226.34).
       The browser then communicates directly
        with that address requesting a response.
       The requested response comes back in
        the form of an HTTP page which is
        displayed by the browser.
What’s in a Web Address?
   Using a Domain Name
        For Brandeis University, you enter: www.brandeis.edu
        A corresponding Internet IP address is substituted (i.e., 129.64.99.138)
         by a “Domain Name Server”
        You could optionally use the IP address to request a page

   URL (Uniform Resource Locator)
        Each page within a Web site has its own unique URL
        The BOLLI Web pages are part of the Brandeis Web site and our “URL”
         is: www.brandeis.edu/bolli/members

   Format Rules
        Cannot contain: spaces or special characters except “-”, “_” “/” and “.”
        Must contain a minimum of three parts separated by a period “.”
        Last part must be one of following: com, edu, gov, mil, net, us, ca, il, fr,
         de, ru, etc.

   Web Address Samples (http:// prefix is optional and implicit)
        www.heier.us
        Finance.yahoo.com
        www.irs.gov
        www.knesset.gov.il
