Here, the batching or grouping of data can be done without user and CPU intervention it can be done offline. ![]() Let’s take the example of batch processing. When processes are not executed under direct control of the CPU, the processing is referred to as offline. #Name 4 system software categories OfflineOnline and Offline Processing: In online processing of data, the user remains in contact with the computer and processes are executed under control of the computer’s central processing unit. The process cannot be executed in the user’s absence. As against this, interactive operating requires user intervention. ![]() IBM’s z/OS has batch processing capabilities. Input data are collected and processed in batches, hence the name batch processing. There is no prompting the user for inputs as input data are collected in advance for future processing. In batch processing systems, programs are collected, grouped and processed on a later date. #Name 4 system software categories manualWhen computers in a group work in cooperation, they make a distributed system.Īmoeba, Plan9 and LOCUS (developed during the 1980s) are some examples of distributed operating systems.īlackberry OS, Google’s Android and Apple’s iOS are some of the most known names of mobile operating systems.īatch Processing and Interactive Systems: Batch processing refers to execution of computer programs in ‘batches’ without manual intervention. Distributed computations are carried out on more than one machine. The development of networked computers that could be linked and made to communicate with each other, gave rise to distributed computing. It can support the multi-tasking of a maximum of four CP/M-86 programs.ĭistributed Operating System: An operating system that manages a group of independent computers and makes them appear to be a single computer is known as a distributed operating system. #Name 4 system software categories plusDOS Plus is a relatively less-known multi-tasking operating system. Palm OS for Palm handheld is a single-task operating system. #Name 4 system software categories windowsMS Windows prior to Windows 95 used to support cooperative multitasking. This kind of multi-tasking is similar to the idea of block multi-threading in which one thread runs till it is blocked by some other event. Cooperative multitasking is achieved by relying on each process to give time to the other processes in a defined manner. If you are aware of the multi-threading terminology, you can consider this type of multi-tasking as similar to interleaved multi-threading. Unix-like operating systems such as Solaris and Linux support pre-emptive multitasking. 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. 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. An 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. ![]()
