Source code

Source code is essentially a human-readable computer programing language. Unlike earlier computer languages that were often a series of numbers and calculations, source code resembles english and often takes the form of long logic statements using words such as: for, while, & if. This was done so that the language could easily be understood and programed by humans.

Because the code is entered in as language and not numbers, the code must be complier before the computer is able to understand it. The complier converts the code into calculations the computer can execute.

Some languages, known as Interpreted languages, ( PHP, Javascript ), are compiled as the computer is instructed to run the code, while other languages such as C# must be compiled before being run. In this case the compiler would output an executable application whose code could no longer be edited.
