A file extension is the last (usually 3) letters after the full stop. These letters define what application the file was written for e.g.
filename.doc = a Microsoft Word file
filename.mp3 = a mp3 audio file
filename.exe = an executable computer program
filename.pages = an apple pages file
filename.jpeg = a picture file
and so on.
Hope this helps,
