| Programs are used to perform specific task and enhance functionality of computer system. | These files are used on windows computers to install or run software applications. |
| Programs are created by programmers in programming language. | Exe files are created by compilers that convert source code in to machine code. |
| Program code are usually written in one or more languages as per knowledge of programmer rather than machine code. | Exe files are usually written according to Microsoft Portable Executable (PE) specifications. |
