where was the first high-level language operating system created
History of programming languages In 1954, language FORTRAN was invented at IBM by John Backus; it was the first widely used high level general purpose programming language to have a functional implementation, as opposed to just a design on paper.[7][8] It is still a popular language for high-performance computing[9] and is used for programs that benchmark and rank the world's fastest supercomputers.[10]
Operating system An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. All computer programs, excluding firmware, require an operating system to function.
