History of operating systems
From Wikipedia, the free encyclopedia
The history of computer operating systems recapitulates to a degree the recent history of computer hardware.
Operating systems (OSes) provide a set of functions needed and used by most application-programs on a computer, and the necessary linkages for the control and synchronization of the computer's hardware. On the first computers, without an operating system, every program needed the full hardware specification to run correctly and perform standard tasks, and its own drivers for peripheral devices like printers and card-readers. The growing complexity of hardware and application-programs eventually made operating systems a necessity.
