Ruby is a scripting language, as are Python and Perl.

Ruby on Rails is a Web app framework that is built on the scripting 
language Ruby.

Ruby on Rails makes it easy to use the language Ruby to write stuff that 
makes a dynamic database driven website work (like a wiki, or a social 
networking site).

Alright I understand that your using ruby for the base of a web
development application but is the same thing or are there differences
in the language to allow the user to do web development in an easier
manner that is geared specifically towards web development.

Ruby is a flexible language, in that you can open foundation classes  
and add new abilities to existing things, like maybe a String gets a  
new method, for example. Rails uses this concept in places to give  
native Ruby constructs new web-centric powers.

As far as I understand, Rails couldn''t exist as it does without the  
metaprogramming madness possible using the Ruby language, so it''s  
pretty much a chicken-or-egg problem. DHH (the original author of  
Rails) is often quoted as saying that he couldn''t have written Rails  
without Ruby. He started out to write it in PHP, and abandoned that  
when it quickly became too hard to get where he wanted to go.

PHP 5.3, which wasn''t around when he did this little experiment,  
begins to introduce some better reflection and metaprogramming hooks  
(the equivalent of method_missing might be the new __call() function  
in PHP5) but even those are seriously limited by the fact that your  
classes are frozen at the time they are subclassed from their parents,  
and cannot be opened again without installing some very cutting-edge  
extensions to the language. These extensions in turn need to be  
compiled into the PHP on your server, so you basically eliminate 99%  
of all hosting providers when you say that.

There''s more, and I''m hardly the expert to explain it all to
you, but
if DHH says it, then it must be true!
