Operating Systems - Term Paper ExampleIt is a place where the mainframe works on sixfold jobs at a once, that is, when one of the jobs is waiting for I/O, the processor can switch to other jobs. It enabled the machine to have a stream of continuous input, computation and return on one disk using disks which held larger buffers (Brinch, 2000).It uses the multiprogramming facility to work on multiple jobs which be interactive. The processor time is shared by the multiple users and this aims at reducing the time that is demand for a problem to be solved. The system is accessed simultaneously by different users at the same time.It allowed programmers to ring memory from logical point of view instead of it being run directly from the hardware (Brinch, 2000). It was set-back used in the personal computers. These days virtual memory software has been developed to serve the functions that were initially done by the direct system.It has the following features Differential responsiven ess it enables different classes of job to be discriminated, and rightfulness this is where all processes are given fair and equal access to resources (Johnston, 2005).The run system is in earn of levels. The functions performed by the layers are related to each other. The lower level performs the most primitive work. This structured operating system breaks the problem into sub problems which are manageable (Johnston, 2005).2. Virtual Memory Since virtual memory allows programmers to consultation memory from logical points instead of being run directly from the hardware has led the programmers to come up with the processor which is an operating system that offers administrators to manage systems and or apply scheduling policies to systems.3. System Structure This operating system is divided in form of levels whose functions are interrelated. It has an advantage to carry out distinctive functions which are done
