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]
Home computer The invention of the Intel 8080 microprocessor chip in April 1974 made practical the development of the (relatively) affordable mass-market microcomputer. In the USA this first appeared in early 1975 in the form of an unassembled kit, the Altair 8800; shortly afterward pre-assembled Altairs were offered. The sudden popularity of desktop computers happened because the 8080 CPU could represent and manipulate 256 discrete values in its 8-bit registers. Thus the 7-bit ASCII standard for the representation of alphanumeric data became feasible for the first time in a machine much smaller and less expensive than the furniture-size minicomputers, with their processors that occupied entire circuit boards. This new class of computer was practical for serious work because it could input, process, and output alphanumeric information. It also enabled sophisticated programs such as database managers and BASIC interpreters to become available to a larger market consisting of people possessing lesser technical skills.
