Data Processing has changed greatly over time. While one can track the beginnings of the modern analytical computer to Charles Babbage (1791-1871), we really saw the beginning of modern day information systems during World War II when they were used as code busters. After the war, few anticipated how much computers would affect our lives. Early on even IBM thought that there would only be a handful of companies that would need a computer.
In those days, computers were massive systems based on vacuum tubes and core memory. With the advent of the integrated circuit, computer architectures took a giant leap forward. The mainframe systems of the late 1980s evolved into Client/Server applications of the early 1990s. In parallel, the Internet grew from a few engineer and research systems to a World Wide network. It wasnt until an Al Gore authored bill allowing commerce to be carried out over the Internet did things really start to change.
