Regular expressions are first of all a theoretical concept. In that sense, regular expressions specify a (often infinite) language of accepted words. Fileglobs are usually not quite as powerful, but have a simplified syntax. There are some very frequently used regular expressions syntaxes as nicely described in the referenced WikiPedia page.
If we start nit picking, we should not mistake one of those syntaxes as the one and only real regular expression syntax.
