"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Both are binary executable files.

COM is the older format used with MSDOS but still (mostly) supported on Windows platforms.  This is basically an image of the program to run and is strictly 16-bit.

EXE is newer and actually there are at least two flavors of EXE files.  MSDOS supported an early EXE file format as an extension to the limited COM format.  Windows 3 later introduced a newer format (called oddly enough the new Executable format) to support features needed by 32-bit programs.  In almost all cases today, EXE files will be new executable or NE format files.  These have additional information in them for resolving load addresses and allowing the program loader to load the program wherever in memory it needs to with a minimum of effort.
