Read More – What is Single User Operating System In this system, single job is divided into various same small jobs, and execute them like as Parallel nature. Multiprocessor O/S gets high performance due to parallel processing. In multiprocessor, do not need to connect all peripheral terminals separately with each processor. Multiprocessor systems are cost effective compare to single processor system in long life because this system is capable to share all input/output devices, power supplies system, and data storage center. For example – if multiprocessor has 6 processors and any one processor does not perform properly, at this stage rest of them processors have to responsibilities for handling this system.Įnhancing the throughput of system, entire system is improved, if couples of processors work with getting collaboration. If due to any reason, any one processor gets fails then do not worry because, entire system will do work properly. There are list of several advantages of Multiprocessor operating system such as Read More – Distributed Operating System Tutorial In this system, it involves some areas of the memory for accessing at the faster rate, and left parts of memory are utilized for other tasks. NUMA Multiprocessor stands for “Non Uniform Memory Access Multiprocessor”. In which, it allows to access all memory at the uniform speed rate for all processors. UMA Multiprocessor stands for “Uniform Memory Access Multiprocessor”. In this system, all types of processors consists own private memory. In this system, each CPU contains sharable common memory. In which, It use the master- slave relationship. In this system, every processor is allotted predefined tasks, and master processor has power for controlling entire system. In which all processors are connected each other with peer to peer relationship nature, it means no master & slave relation. In this system, every processors have own identically copy of operating system, and they can make communication in between each other.
