Background
The user had sole use of the machine and would arrive build up with program and data, often on punched paper and tape. The program would be loaded into the machine, and the machine would be set to work until the program completed or crashed. Programs could generally be debugged via a wait panel using switches and lights. It is said that Alan Turing was a master of this on the early Manchester Mark 1 machine, and he was already deriving the primitive conception of an operate system from the principles of the Universal Turing machine.

The processor era
It is generally thought that the first operating system apply for real work was GM-NAA I/O, produced in 1956 by superior general Motors Research division for its IBM 704. [1] Most other early operating systems for IBM mainframes were also produced by customers.[2]
Early operating systems were very diverse, with for each one vendor or customer producing one or more operating systems specific to their particular mainframe computer. Every operating system, even from the same vendor, could have radically different models of commands, operating procedures, and such facilities as debugging aids. Typically, each time the manufacturer brought out a newly machine, there would be a new operating system, and most applications would have to be manually adjusted, recompiled, and retested....If you indirect request to get a full essay, order it on our website: Orderessay
