Designed by engineer Gardner Hendrie for Computer Control Corporation (CCC), the DDP-116 is announced at the 1965 Spring Joint Computer Conference. The basic computer cost $28,500. Operating systems can be found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers. This separation of concerns has led to system engineering practices that are not designed to reflect, detect, or manage the interdependencies of such aspects, for example, the interplay between security and safety in modern car electronics, or between security, privacy, and reliability in connected medical devices. This is the reason why system software is also known as 'low-level software'. I.e. The computer system is not a simple machine. Computers have created a very effective information system to help streamline the management of an organization. Modern computers usually have word sizes of 16, 32 or 64 bits but this varied considerably from one system to another in the past and comprised any of 8, 9, 12, 16, 18, 24, 32, 36, 39, 40, 48, 60 or 64 bits depending on the computer.
