The InterNet is a global collection of inter-connected networks, connected using the TCP/IP protocols which evolved from ARPANET in the 1960s and 70s and was made more prominent in the 1990's as the 'Information Superhighway'. By connecting tens of thousands of independent networks into a vast global internet it is the largest wide-area network, allowing businesses and people across the entire planet to communicate. While the internet is dependent upon the global communications net (telephone and network cables, radio, computers, etc.), it itself is a hybrid of these technologies which 'floats' upon them as a separate organism.
And what exactly was the "information superhighway" other than a great deal of hype? Was it a technological change? A social change? A policy change? Was it anything at all?
What is the Internet?
The Internet is...
Actually, the internet floats on top of the global communications net (GCN). Most services making use of the GCN do so through one or more protocols and that's really all the internet is: a protocol of communication. People tend to think the internet is what the GCN is. They think the internet is a bunch of wires and radio signals and so-on, but they don't realize the wires and types of signals used are only linking the various transmitters and receivers that use the protocol known as the internet.
The GCN would more accurately be described as the 'nervous system of modern society', not the internet.
That depends on your definition of modern society (vs the old kind)
This is very hyperbolic, the media is more accurately described as this, but the Internet is a subset of the media.
Oh really? Then please tell us where hypermedia like web sites, blogs and wikis exists outside of the internet. Or hell, where exactly is Usenet outside of the internet? in UUCP over modems? Where is google?
And in fact, it's not much of an exaggeration. WithinTwentyYears, the internet will have replaced most or all other media. In particular, it's already replaced half of publishing in the last twenty years, and will do the same for the other half in the next twenty. There isn't going to be a publishing industry in 20 years.
