Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources to multiple users. Single-user operating systems have no facilities to distinguish users, but may allow multiple programs to run in tandem. A multi-user operating system extends the basic concept of multi-tasking with facilities that identify processes and resources, such as disk space, belonging to multiple users, and the system permits multiple users to interact with the system at the same time. 32-bit versions of both Windows NT and Win9x, used pre-emptive multi-tasking. 16-bit versions of Microsoft Windows used cooperative multi-tasking. Cooperative multitasking is achieved by relying on each process to provide time to the other processes in a defined manner. Unix-like operating systems, e.g., Solaris, Linux, as well as AmigaOS support pre-emptive multitasking. In pre-emptive multitasking, the operating system slices the CPU time and dedicates a slot to each of the programs. Multi-tasking may be characterized in pre-emptive and co-operative types. This is achieved by time-sharing, dividing the available processor time between multiple processes which are each interrupted repeatedly in time-slices by a task scheduling subsystem of the operating system.

Types of operating systems Single- and multi-taskingĪ single-tasking system can only run one program at a time, while a multi-tasking operating system allows more than one program to be running in concurrency. Popular hard real-time operating systems include FreeRTOS, Micrium and VxWorks.

The first eight of these examples share roots inUNIX. Operating systems are found on many devices that contain a computer-from cellular phones and video game consoles to web servers and supercomputers.Įxamples of popular modern operating systems include Android, BlackBerry, BSD, Chrome OS, iOS, Linux, OS X, QNX, Microsoft Windows, Windows Phone, and z/OS.

Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.įor hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or be interrupted by it. Application programs usually require an operating system to function. The operating system is an essential component of the system software in a computer system. An operating system ( OS) is software that manages computer hardware and software resources and provides common services for computer programs.
