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.
