In pre-emptive multitasking, the operating system slices the CPU time and dedicates one slot to each of the programs. Multi-tasking can be of two types namely, pre-emptive or co-operative. Multi-tasking and Single-tasking Operating Systems: When a single program is allowed to run at a time, the system is grouped under the single-tasking system category, while in case the operating system allows for execution of multiple tasks at a time, it is classified as a multi-tasking operating system. Unix and OpenVMS are examples of multi-user operating systems.

Windows 95, Windows 2000, Mac OS and Palm OS are examples of single-user operating systems. But for a Unix-like operating system, it is possible for two users to log in at a time and this capability of the OS makes it a multi-user operating system. Rather, only the network administrator is the real user. Being able to have multiple accounts on a Windows operating system does not make it a multi-user system. Single-user operating systems, as opposed to a multi-user operating system, are usable by only one user at a time. Time-sharing systems can be classified as multi-user systems as they enable a multiple user access to a computer through time sharing. Multi-user and Single-user Operating Systems: Computer operating systems of this type allow multiple users to access a computer system simultaneously.

Windows CE, OS-9, Symbian and LynxOS are some of the commonly known real-time operating systems. An event-driven system switches between tasks based of their priorities while time-sharing operating systems switch tasks based on clock interrupts. They either have an event-driven design or a time-sharing one. The main object of real-time operating systems is their quick and predictable response to events. Real-time operating systems often use specialized scheduling algorithms so that they can achieve a deterministic nature of behavior. Real-time Operating System: It is a multitasking operating system that aims at executing real-time applications. Here is an overview of the different types of operating systems. In short, an operating system enables user interaction with computer systems by acting as an interface between users or application programs and the computer hardware. Users interact with a computer operating system through Command Line Interfaces (CLIs) or Graphical User Interfaces known as GUIs. Users and application programs access the services offered by the operating systems, by means of system calls and application programming interfaces. It hosts several applications that run on a computer and handles the operations of computer hardware.

Let us look at the different types of operating systems and know how they differ from one another.ДЄn operating system is a software component of a computer system that is responsible for the management of various activities of the computer and the sharing of computer resources. An OS dissociates the programs from the hardware and simplifies resource management. Operating systems that create a link between users and the applications form the core of computer systems.
