What is the Internet?

I recently signed up for an online marketing course on Traffic Synergy, and they had an interesting article on What the Internet/Cyberspace is and i thought i should share it...

The internet is up there with fire, the wheel, the light bulb, in terms of technological advancement that has revolutionized the way the world thinks and works.

The internet has made so many things possible that even as little as ten years ago seemed virtually impossible – like video calling some one in based in Russia while you are based in Cape Town.

The internet is a global system of interconnected computer networks, that interchanges data via copper wires, fiber-optic cables, wireless connections and other technologies. In short the internet allows a computer based in Cape Town to communicate with a computer (usually a server) based in Russia. Computers communicate with each other via the internet almost instantaneously, and is dependant on the physical limitations of the technology being used to relay the communication.

The internet is also known as the information super highway, and allows web users to access information, download and upload electronic files (like audio, text, video, image, and others) to be viewed for the whole world to see. Websites, blogs, vlogs, emailing, IM, VoIP (internet calls) are a few of the applications of the internet that are common place in daily life.

The internet is still in its infancy in terms of application development and regulation. International bodies like the World Wide Web Consortium and Internet Protocols are being developed to try to bring order to the chaos that is cyberspace.

This phenomena has transcended all barrier's and made the world "seemingly small"
Question: has it introduced a new way of doing business, communicating etc or has it made us lazy of actually interacting with other humna beings?

Either way, i quite enjoy it's usefulness and how it's made my life extremely easy...and more importantly it has inspired a lot of business ideas.We now have a new breed of Executives (Online Executives). Powerfull business people who have made a chunk of their money from this phenomenon.

But thats just me, you can draw your own conclusion.
