A multiprocessing operating system uses multiple processors to execute multiple processes in parallel, significantly improving system performance, throughput, and responsiveness. This allows for true parallel processing, as different tasks run simultaneously on different processing units, rather than being rapidly switched between as in multitasking. Operating systems like Linux, Windows Server, and Mac OS support multiprocessing, managing resource sharing, coordination, and fault tolerance across the multiple CPUs or cores within a single system. [1, 2, 3, 4]
How it Works

• Multiple Processors: The core feature is the use of more than one CPU or processing core in the system. [2, 3]
• Parallel Execution: The operating system distributes tasks or processes across these multiple processors, allowing them to execute at the same time. [1, 3]
• Resource Sharing: Processors in a multiprocessor system typically share resources such as main memory and input/output (I/O) devices. [3, 5]
• OS Coordination: The operating system's role is crucial in coordinating the activities of all processors to ensure proper execution and prevent conflicts when accessing shared resources. [3]

Benefits of Multiprocessing

• Increased Performance: Tasks can be completed faster by dividing them among multiple processors, reducing overall execution time. [1, 5]
• Improved Throughput: The system can process more jobs or tasks simultaneously, increasing the total amount of work it can handle. [6, 7]
• Enhanced Reliability: If one processor fails, other processors can continue to work, preventing the entire system from halting and enhancing fault tolerance. [5, 8]
• Scalability: The system can more effectively handle demanding applications and increased workloads by adding more processors. [1, 4]

Examples of Operating Systems UNIX, Linux, Windows Server, and Mac OS. [3, 5, 9]
