Frames:
 
 
  
The above is 
  a very standard division of a website into 3 frames: navigation, logo, content
  with frames you see more than one html page at once. Here, above, 
  we see 3 html pages---3 frames.
  The great thing about this is that you can just have a section 
  of your site change while the rest can remain the same. So, you can load a new 
  page lets say into the content.html area by clicking in the navigation.html 
  area which doesn't need to refresh.
