Internet
The Internet is, literally, a network of networks. It is made of thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to humble PCs in peoples homes and offices. Despite the recent publicity, the Internet is not a new thing. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defenses communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, but instead the information was dispersed across thousands of machines. A protocol known as TCP/IP was developed to allow different devices to work together. The original network has long since been upgraded and expanded and TCP/IP is now an overall standard. The Internet has gone on now to fulfill a great deal more than its intended purpose and has definitely brought more good than bad. Millions of people worldwide are using the Internet to share information, make new associations and communicate. Individuals and businesses, from students and journalists, to consultants, programmers and corporate giants are all harnessing the power of the Internet. For many businesses the Internet is becoming
