The Internet, like its former early twentieth century counterpart the radio, is quite literally, a network of networks. Both, at their primes, comprised of tens of thousands of interconnected networks spanning the globe. Millions of people worldwide use both the internet and the radio as a means of sharing information, to make new associations, and to communicate. Individuals and businesses, from students and journalists, to consultants, programmers and corporate giants are all harnessing the power of the internet.
