To avoid the drawbacks of early systems the batch processing systems were introduced. The early systems required more setup time.To overcome this drawback, batch processing is used where the more set up time was reduced by processing the jobs in batches in this approach similar jobs were sent to the CPU for processing and were run together.The important task of the batch processing system is to automatically keep executing the job in batches to reduce the setup time.In the early job processing systems, the jobs were placed in a job queue and the memory allocated or managed by the primary ...

Let us understand the characteristics of mainframe operating systems.Characteristics of Mainframe operating systemsThe characteristics of Mainframe operating systems are explained below −These systems have a large number of CPUs each having great processing power. All the CPUs with great processing power are combined into the Mainframe which as a result has the greatest processing power.The memory of the mainframe operating system is very large. It can even be about more than 8GB.Increased Performance/throughput as task load is shared: Mainframes systems share the task load among different processors and input/output devices. Thus, the processing power and efficiency increases multifold.Supports Time Sharing ... Read More

Inside the computer system the memory hierarchy is arranged from fastest to the slowest as given below −RegistersCaches memoryMain or Primary MemorySecondary MemoryThe memory hierarchy is depicted in the diagram given below −Let us discuss about each memory in detail.RegisterRegisters are very high speed memory, which is present inside the CPU. It is a temporary storage device that means it stores the data temporarily. Generally, they create a general purpose register file to store data. The register file capacity is 32 data words, and each register can be read or written from within a single clock cycle.Cache MemoryThe cache memory ... Read More

Operating systems allow user application applications to interact with the system hardware. The operating system itself does not provide any functionality but provides a situation where various programs and systems can perform useful functions.It is software which handles the computer's functionality like scheduling, input/output operation resource allocation, files system manipulation, etc and also acts as an interface between the User and hardware.System views can be improved using a new GUI and adding new features to the OS which will result in a better user experience.The operating system is observed from the user point of view or system point of view.Let ...

An operating system allows the user application programs to interact with the system hardware. Operating systems provide an atmosphere where different applications and programs can do useful work, but it does not provide any function by itself.The operating system is observed from the user point of view or system point of view.Let us discuss how an operating system is observed from a user point of view.User ViewThe user view depends on the system interface. The different types of user view experiences are explained as follows −Suppose if the user is using a personal computer, the operating system is designed to ... Read More
