How the Internet works
About This Course
Can you still picture life without the internet? In the last decade or so, the internet has cemented its place at the centre of many aspects of our lives: social communication, work, research, banking, shopping, storing photos and videos; we are heavily dependent on it.
But most of us never really question how the internet works - until, perhaps, something breaks down and information is lost, or we are prevented from accessing a website or account.
The internet is in fact a complex and diverse infrastructure; an infrastructure that allows you to connect to it in either a less secure or a more secure way. This all depends on the choices you make; the tools and services you use.
In order to make more secure choices, you don’t need to be a tech expert - but you do need to understand the fundamentals of how the internet works. This knowledge is your foundation - from here, you can become an informed internet user. Like crossing the street - you do not necessarily need to know how to drive a car, but you do need to know to look left and right before you cross.
In this course you will explore the infrastructure of the internet - how it works, who owns it, and how you can make informed choices depending on your own privacy and security need.
