Source code is the true code used by a programming language. You use source code to tell the computer what you want it to do when something happens. The thing is computers only understand machine language("Binary") which is a First Generation Programming language which is also why everything is converted back to kilobytes and so on. The job of the compiler is to convert your source code into Machine Language.
