OPREATING SYSTEM (OS)

The most important that runs a computer is operating system. An operating system is abbreviated as OS, an OS controls and manages the hardware and other software on a computer. Operating system, a programmed that load in computer at initial step by a boot program. An operating system manages to control all the programs that are running in a system. OS is a powerful, and usually large, program. Operating system is software that controls PC’s hardware and software. Operating system (OS) is a software program which helps computer

Operating system keeps tracking files and directories on the disk and it also controls disk drive and printer. Operating system got many responsibilities and power as in large system. It work like a traffic controller it does not mix different program and user working at a same time, operating system does not let different program and user to interfere with one and other. Operating system in also responsible of security. Operating system ensures that the unauthorized user can not use or access computer. Software platform is also been provided by operating system. It is also called application program. By commanding to a system, user normally collides with operating system. DOS is an example of it. Such commands like copy or rename are contained in an operating system. It copies or changes the name of file. Command processor accepts the command that user give, in one part of an operating system, it is also called command line

The Basic features of OS were developed in the 1950 such as resident monitor functions it automatically run different programs in same time in succession to speed up processing. Earlier in 1960 OS was not existed in their modern and complex form. In 1960 single operating system was introduced by IBM. A distant descendant is the current operating system in IBM. The scope of operating system was developed by Control Data Corporation. In 1980 when personal computer becomes famous at that time operating system was made similar. The earlier electronic digital system in 1940 had no operating system. A computer can only work at a single program at a time, earlier in 1950. A program was uploaded into a machine and machine set its self to work until program complete or crashed. Later machine were built to libraries of program which link users program to assist in operation. It was called the genius of modern day O S. But still machine were running on single job at a
