4.01 Transitional
The whole point of HTML 4.01 transitional was to be able to use previous hyper text markup languages such as HTML 2.0 etc... and still have the browsers that parse the written 2.0 etc.. Languages properly without any or as little error as possible.
Note: You never need to use HTML 4.01 transitional unless you plan on writing HTML 2.0 language which is absolutely unnecessary. This document format is only used by the pioneers of web documents when the internet was first created. SO they could get used to writing proper HTML 4.01 Language.
4.01 Strict

HTML 4.01 Strict is the industry standards professional format to writing proper hyper text mark up language.
This is the document format you use to write your HTML code if doing anything. This is really the only document format used in the professional world to write HTML. This format is used because the industry has upgraded from previous mark up languages such as HTML 2.0. So the proper version to write mark up language is HTML 4.01 Strict. Not only is this a document format but this is the way you write professional or in other words the only way you should write proper mark up.


The difference between HTML and XHTML

There really is not much difference between these 2 document forms. The only differences between the 2 are the way they are executed or "parsed" from a web browser. When you are launching (a.k.a executing, parsing) an HTML document with a web browser. What it is doing is putting more strain on your computer. It takes more computing power or "RAM" to load this document because there is more data within the Document type definition or "DTD " so the server it is pulling it from is relying more on yoru computer and your browser to render and read it properly.

With an XHTML document. The extensible feature of this document allows your computer to pull it from another server. So basically the server is already reading the document for your browser and all your browser does is show it and partially interpret what needs to be seen. Since this document XHTML is a definition from an already written document (that you don't see) the DTD is kind of already rendered within the XHTML document. So it does not take as much computing power to parse the document as it would with an HTML document.
