- BBM - ? (“Black Berry Messenger”:))
West Coast

Thank you for your contribution! 
Interesting to see how the difficulties in standardised communication of data between each organisations network, lead to the development of TCP/IP and a standard that we used today. Allowing us to have the internet ! Very interesting!

How did they connect the supercomputers?
Transmission Control Protocol (TCP)/Internet Protocol (IP). Layer 4 and 3 technologies respectively.
Is TCP and IP different technologies? Why do we need to separate the name with a / (slash)?

Were there other internet precursors around the world? How did the internet become “world wide”?

The internet was opened up to commercial use back in/around 1985, I think. Not too sure of the order of events but the creation of the www on top of the 'net was key to the internet becoming world wide. Google Tim Berners-Lee if you haven’t already come across this bit of history in the introductory bits of FSE.

The connection was by telephone lines. TCP/IP facilitated communications over telephone networks.

is it just me or does the ARPANET looks like a stretched swan. Maybe they can call it SWANNET (its catchy too!)
Also I have a question so did the initial ARPANET network had huge copper wires underground going from one end of US to another end. How did the networks communicate with each other with the limited technology of 1969?
