When a process is removed by the operating system from the CPU, the information on the current condition of that process needs to be stored, so it is possible restore the process to the same condition when it is return to the CPU. Explain how the relevant information on the condition is stored, and provide two examples of what information is stored. (b) (i) Explain why priorities are used by operating systems when scheduling processes.
