Commands, data, variables, and conditions help build the most simple programs and there are certainly many more components of any programming language. But when they're typed into a programming language and compiled to create a an executable file (a file ending with the .exe extension), they turn into a software application. A program that needs 14MB of memory will generate errors on a computer that only has 4MB of memory if it runs at all. The same goes for disk space, monitor color depth and resolution.
