The internet has changed a lot since HTML 4.01 became a standard in 1999.
Today, some elements in HTML 4.01 are obsolete, never used, or not used the way they were intended to. These elements are
re-written in HTML5.
To better handle today's internet use, HTML5 includes new elements for
better structure, better form handling, drawing, and for media content.

A fundamental rule in a three-tier architecture
is the client tier never communicates directly with the data tier; in a
three-tier model all communication must pass through the middleware
tier. Conceptually the three-tier architecture is linear. However, the
MVC architecture is triangular: the View sends updates to the
Controller, the Controller updates the Model, and the View gets updated
directly from the Model.
