A Brief History of the Computer

IBM System/360, 1964
Part of a family of interchangeable computers, the IBM System/360 mainframe was the first to cover a complete range of applications, from small to large, from commercial to scientific. Users were able to enlarge or shrink their setup without having to make headache-inducing software upgrades as well. Higher-end System/360 models had roles in NASA's Apollo missions as well as air traffic control systems.
