Coding is the primary method for allowing intercommunication between humans and machines.

Early coding was done through physical punch cards and similar methods.

As digital computers were created, early programming languages like BASIC, FORTRAN and COBOL were used, each with its own syntax and operators.

In the personal computer and Internet age, developers and computer programmers typically produce code in modules that correspond to individual computing tasks. These modules are put together in a collective framework or project, such as an individual software application.

Since these projects are usually more complex, professionals have established many more conventions and strategies for computer coding in order to make finished products more stable and functional.
