How was the internet first developed?

This week an inquisitive TPL Kids visitor has wondered: How was the internet developed? 

The earliest form of the internet was funded by the US Department of Defence. What started out as ARPANET (Advanced Research Projects Agency Network) in the late 1960’s by researchers, has evolved into a network used by almost everyone.  ARPANET used packet switching to allow multiple computers to communicate on a single network. Soon after, TCP/IP (Transmission Control Protocol/Internet Protocol) was developed to create a standard for how data is transmitted.  

UK computer scientist Tim Berners-Lee is recognized as inventing the world wide web in its recognizable form. While the internet is simply a network of networks, the world wide web is the system we use to access the internet. Tim Berners-Lee created the first web browser and web server. 

So the next time you’re searching for cat pictures, remember to thank Tim Berners-Lee who made it all happen.
