The Internet started as a project by the Advanced Research Projects Agency of the U.S. Department of Defense in the late 1960s. Since then, it has evolved to be the biggest network of all, although its core function, to create a network of networks, has not changed. It is this very connectivity that gives rise to a series of applications making the Internet such an interesting proposition for a number of business and personal activities.
