On the nature and development of Operating Systems
I have been asked to do an assignment on the nature and development of Operating Systems. I accessed information on the internet to broaden my understanding and to enable me to complete assignment.
I will start by giving an overview of the history and development of operating systems. I will then go on to discuss the role of an operating system and identify the main purposes and will look in more detail at four of these. I will then look at available operating system and finish by doing a summery.
The history of operating systems is very long and there have been many different variations and many different kinds of operating systems for different situations.
To begin with computers did not have operating systems the people working on them had to switch lots of switches to different states of on and of 0's and 1's or binary just to execute a single line of code. This problem was solved by putting the work on some kind of input medium like magnetic tape, punched card and paper tape the jobs still only ran one at a time and the results would come out on the same kind of medium plus printed paper. Some early operating systems include the FORTRAN Monitor system for the IBM 709 and the General Motors Operating System for the IBM 701.
The next big development was the Command Line Interface (CLI) operating system which as the name suggests you have to write a command in and then the computer executes that command after you presses enter. You can use a CLI to do lots of different tasks such as running a program a graphical output from the printer and manipulating the file system i.e. creating a file, deleting a file or modifying a file.
One of the most popular CLI operating systems is MS-DOS, which was an offshoot of QDOS or the Quick and Dirty Operating System as it was better known. This in turn was a cut down version off CP/M operating system.
