In this last video we explore how the whole idea of networking computers came about and how folks utilized design Thinking to make that all happen
Self Check Questions
Reflective Question 1So all along we have been told that ARPA invented the Internet... and in this episode we are now being told that it was Tim Berners Lee (CERN) that invented the World Wide Web (www)... how does that all add up?
ARPA built something for military use on a single, closed-ended system (all the computers were/had to be compatible).. what Berners Lee did was figure out how to make it more ubiquitous and create a system to join incompatible closed-ended systems together.... incompatible computers joined together (utilizing a system of Uniform Resource Locators (URLs)) plus other enhancements.
Design Question: How can we take the basics of packet switching and the benefits of the Net and take it to the next level and join closed-ended systems together?

Reflective Question 2OK.. was the introduction of CERN to the equation just another 'false flag'? Cringley is now saying that it wasn't Berners Lee but Tim Nelson who really invented the world wide Web (Zanandu)? Which one was it?
Well, technically, Nelson didn't 'invent' anything .. he created a design for it .. the seed/kernel .. bringing us to the next
Design Question: is a 'solution' is not a real solution unless it can be (and is tested)? ... the real teachable moment here is that if you come up with an idea or solution it really is not one unless you test it to see if it actually works... modeling is not building... that is why in this degree program then end is for you to go out and build the solution you come up with and even possibly take it to your dissertation and validate it. The goal is not to simply brainstorm and cogitate but to actually take action on something.. this is the major difference between a Ph.D. and an Ed.D. (just in case you are still wondering).

Reflective Question 3Last question in this series .. what design question formed the basis for the development of Novell?
Design Question: How can I take the basic idea of networking computers that are remotely located all over the world and utilize those same principles to network local computers? It was not that obvious... back then the idea of actually asking that question had never come up.. PCs were thought of as not necessary to be networked... what drove the need (among other things) was 1- the need to chare information and 2- the need to back up the data on all computers without having to go to each one and do it locally.
Later on customer service entities needed the ability to be ably to drop in to others for support and training.. that came about a long time later and in the early days was considered to be (for many of the close ended computers) an impossibility or to highly expense... amazing how far we have come simply by one person or group asking the right questions to build on what is previously known about something (and discovering how to actually build that solution).
