In 1623, Wilhelm Schickard built the first add/subtract machine. This was followed by the first machine that could perform the four basic mathematical operations, created by Von Leibniz in 1673. Then, over the next 300 years, a series of machines were invented to capture and process information.

In 1964 IBM introduced IBM 360 and in the early 1970s, Intel introduced the first microprocessor. A scant decade later, IBM introduced the PC, Microsoft gave us DOS, and Lotus the spreadsheet. Almost simultaneously, the LAN came to be as Bob Metcalfe scribbled Ethernet on a napkin in 1973. By the late eighties, what had been a project to survive a cold war attack became the public Internet, and just five years later the Web was born.
