What Are Operating System Environments?

Operating System Environments
       
       Major differences in how the operating system exercises its management function are evident in single-tasking, multi-tasking, and multi-user computer environments.
         
          Single-Tasking Operating Systems

          A single tasking operating system is an operating system that execute only programme at a time, whether it is a spreadsheet, or a word processing, or whether it is printing of a document. Most of the earlier operating systems were single tasking operating system.
         
          Multitasking Operating System

       A multitasking operating system is an operating system that execute several programmes at a time.
Business professional typically do several things or task at once. Microcomputers usually used windows to display all the task that are active at the same time. A window is one area of a divided display screen. Each window has all the capabilities of a single display.

      Multi-user Operating Systems

      The processing power of larger computers can utilized more efficiently if a number of individuals are able to access them at the same time. This is common in the time- sharing environment of local area networks and wide area networks. With these multi-user systems, the operating system allocates limited CPU time to each user, separate job requests, and works hard to avoid mix-ups in sending the output switching from one user to other, to an output device.
