So what constitutes a code?

A set of codes and conventions that work together to make you feel happy, angry, afraid, excited.To make you want to buy a particular product --a refreshing drink, a new phone.To style your hair a certain way.To cheer for the hero or boo the villain.Welcome to the family tree of technical codes.So what constitutes a code?First of all, it has to be recognized by all who read it.Imagine a busy city where motorists don't know how to read the traffic signals.We all have to know red equals stop,green means go, for the system to work.Otherwise it would be chaos.
