"The operating system is a collection of programs which, together, manage all the basic functions of a computer. The operating system runs other programs (such as a word processor or graphics editor), manages the storage of your own documents, and coordinates the functions of the computer itself and all the devices connected to the computer. Windows Me, Mac OS and Linux are three examples of operating systems. A program written to work under one operating system will not work on another operating system (a different version must be written for each operating system - such as Microsoft Office for Windows and Office for the Mac.)

"Necessity of an Operating System : Computer System performs all the tasks with the help of hardware and software jointly. To use computer in different application areas, a user has to write proper software. A user who is writing a program or a software need to know about details of hardware, which is a very difficult task. Therefore there should be an intermediate component between user and computer hardware. The execution of all commands given by the user and all instructions given by various softwares are the responsibility of Operating System. Operating System provides various services like program execution, I/O operations, resource allocation etc. for convenience of user or efficient operations of system itself.
