Overview of Operating System
Operating system is the core of computer programming that primarily deals with computer architecture. An operating system maintains a proper balance between the software and hardware present in a computer system. Operating system is basically an application program that serves as an interface to coordinate different resources of computer.
History of Operating System
History of operating system is one of years of experimentation. Operating system was absent in the first commercial form of electronic computer launched in 1940's. Rows of mechanical switches were used to enter programs. At that time programming languages were not in use. Naturally there was hardly any idea about operating system.
The next generation of computers was introduced in the early phase of 1950's. The earliest version of operating system was used by the General Motors Research Laboratories. IBM 701 was the first operating system equipped computer architecture. It was a major mark in the history of operating system. This type of computer system was known as batch processing system.
The batch processing system continued to dominate the next decades of computers as well. However, simultaneous peripheral operations on line (Spooling) were the added techniques used in 1960's. This new technique attempted to make the programming operations quicker than before.
The fourth generation of computer successfully used the contemporary operating system. With chips, large scale integration circuits and operating system, the era of personal computer started its journey in 1970's. MS-DOS, Intel 8088 CPU and UNIX are the operating systems that primarily dominate the field of personal computers.

In conclusion it can be said that the present form of operating system is the result of gradual evolution of computer system over years.
