At its most basic – coding is telling a computer what to do!

Have you ever wondered how computers work – why do they do what you want them to do? Well, it’s because they’ve been told to do exactly that. And the way we tell them is through coding. Coding is the way we format instructions that a computer understands and allows it to carry out the functions we want it to.

Every electronic  devices from laptops, desktops, phones, and tablets require code to operate. Every website you are on and every app you use can only operate because someone has written a code that makes it work.

Coding allows us to build programs, such as websites and apps. Coding also tells computers how to process data in better and faster ways. These codes need to be written and these coders are often known as computer programmers.
