That's right, johnmiller, commonly a filename has a short group of characters (usually 3) after the last full stop. That's the file extension, and denotes what type of file it is: the operating system normally identifies what to do with it (i.e. open it with a particular application, run it, etc) from this. Sometimes a filename will have more than one stop in it, in which case only the characters after the last stop will be the extension - as in my example of "clickme.jpg.exe" above.
As for the meaning of each extension, there's an awful lot of them in common usage, and sometimes the same extension may be used for different identifications: in this case, whatever application you have installed on your system with the file type registered to it will determine how it's identified.
If you want to know what any particular extension is for, google it. There are sites for identifying file extensions; you're bound to come across some of them if you do.
