The term "information technology" came about in the 1970s. Its basic concept, however, can be traced back even further. Throughout the 20th century, an alliance between the military and various industries has existed in the development of electronics, computers, and information theory. The military has historically driven such research by providing motivation and funding for innovation in the field of mechanization and computing.

The first commercial computer was the UNIVAC I. It was designed by J. Presper Eckert and John Mauchly for the U.S. Census Bureau. Since then, four generations of computers have evolved. Each generation represented a step that was characterized by hardware of decreased size and increased capabilities. The first generation used vacuum tubes, the second used transistors,the third integrated circuits, and the fourth used integrated circuits on a single chip. The late 70s saw the rise of microcomputers, followed closely by IBM’s personal computer in 1981. Today, the term Information Technology has ballooned to encompass many aspects of computing and technology and the term is more recognizable than ever before. The Information Technology umbrella can be quite large, covering many fields. IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform include, but not limited to.|}} ch generation represented a step that was characterized by hardware of decreased size and increased capabilities.
