In a normally operating system, once an I/O device is identified, it will use the CPU to transfer the information into the memory before performing any operations on it, like processing and transmitting. The working of the parallel operating system is such that the CPU and its components are divided into smaller parts, each having full speed and power. Further, each part is broken down into a series of instructions executed simultaneously on different CPUs. It is an evolution of serial processing wherein tasks are broken down into manageable tasks that can be executed concurrently.
It is used for dealing with multiple processors simultaneously by using computer resources which include a single computer with multiple processors and several computers connected by a network to form a cluster of parallel processing or a combination of both. Parallel operating systems are designed to speed up the execution of programs by dividing them into multiple segments. Disadvantages of parallel operating system.Advantages of parallel operating system.Application of parallel operating system.How do Parallel Operating Systems Work?.These systems are called multiprocessor systems or tightly coupled systems. Justify your answer with practical examples.The parallel processing system is designed to speed up the execution process of programs by dividing them into multiple segments and processing them simultaneously. Discuss the reasons why you consider modern (time- EV with the notion that "Modern operating systems still have more room for improvement". simple batch processing operating systems, and explain practical limitations for their use, giving appropriate examples to illustrate your (ii).
serial processing operating systems and (B). Discuss, in detail, reasons why an operating system is considered as a resource manager and explain how it manages the various resources in the context of computer-based information systems in use at a tertiary institution like AIT. Question 2 Operating systems have suitably and rapidly evolved over the years from serial processing operating systems to today's robust multiprogramming, time-sharing and real-time operating systems.
