HISTORY OF OPERATIMG SYSTEMS Operating systems (OS) provide a set of functions needed and used by most application programs on
a computer, and the linkages needed to control and synchronize computer hardware. On the first computers, with no operating system, every

The concept sold a lot of computers, but it took its toll. Users running particular applications that did not require this kind of power and this
played heavily in increased run–time over head, learning time, debugging time, maintenance, etc. Third generation operating systems were
multimode systems. Some of them simultaneously supported batch processing, time sharing, real–time processing, and multiprocessing. They
were large and expensive. Nothing like them had ever been constructed before, and many of the development efforts finished well over budget
and long after scheduled completion. These systems introduced to computer environments a greater complexity to which users were, at first,
unaccustomed. The systems interposed a software layer between the user and the hardware. This software layer was often so thick that a user
lost sight of the hardware and so only the view created by the software. To get one of these systems to perform the simplest useful task, users
had to become familiar with complex job control languages to specify the jobs their resource requirements. Third generation operating systems
represented a great step forward, but a painful one for many users. Examples include: 1.1966, DOS/360. 2.1969, UNIX. THE 4TH
GENERATION (mid 19670's– present) Fourth generation systems are the current state of the art. Many designers and users are still smarting
