The first commercial computer was developed by John Eckert and John W. Mauchly in 1951 and was known as Univac 1. For the next 25 years, mainframe computers were used to do calculations in large corporations. Supercomputers were used in Science and Engineering, for designing aircraft and nuclear reactors, and for predicting worldwide weather patterns. Minicomputers came on the scene in the early 1980’s in small businesses, manufacturing plants and factories. Computers today are divided into four categories by size, cost and processing ability. They are supercomputers, mainframe, minicomputer and microcomputer more commonly known as a Personal Computer. Personal computers can be further divided into desktop, network, laptop and handheld. By the 1970’s with the development of the Internet by the US Department of Defence, the Information Age was
