sou] The source code refers to the programming code that is written to develop the program, oftentimes it is compiled before it is run, therefore unviewable to the end user. Once the program is compiled, it is readable by a machine, but very difficult for a programmer to understand. All free software (open source) programs are distributed with the source code as well as the compiled object code. One nice thing about writing web documents is you can see the source code for the page you are viewing. This allows you to more easily learn html. If you are using internet explorer to view this page, simply click on the edit option at the top of the page, then select source. A similar process works with Firefox.
