I think that 'Paradigm' is word for 'Way of Thinking', or 'Viewpoint'.
Is there single best and only approach to Programming or Information Technology?
I think no, for there are many standards, or 'branches' in this field of knowledge. And many languages, libraries, etc.. Each serves different purpose, and good ones can work with others (for example by serving a 'Web Service').
For example, when i use word 'Channel', i mean something differing from 'Channel' defined in many other language(s).
Everything depends on context.
