In these, the jobs with similar needs were batched up and executed together. The different types of operating systems are: Batch Operating Systems History of Operating SystemĪ brief history of operating systems in tabular form is given as follows: Generation This means that any new functions should be easily integrated with the computer without disrupting the working of the operating system. The operating system should not hinder the evolution of the computer system. The operating system should provide hardware resources to the different application programs in such a way to maximize efficiency. The interface should make the interaction with a computer system simple and hassle free. These are: ConvenienceĪn operating system should make a computer easy and convenient to use. In general, an operating system provides mainly three functions. It makes sure that adequate hardware resources are distributed evenly among various applications so they can all complete their execution. The operating system coordinates between the hardware and the application programs. The place of an operating system in a computer can be demonstrated aptly using the following diagram:Īs can be seen from the above diagram, the computer system is divided into four components namely, hardware, operating system, application programs and users. Operating system by itself does not provide any function but it provides an atmosphere in which different applications and programs can do useful work. An operating system is a construct that allows the user application programs to interact with the system hardware.
