Operating system is one of the most important components in computers. Every computer system requires a microelectronic chip called central processing unit (CPU) plus operating system (OS) software. The OS directs instructions requested by the application software, while the CPU performs numerical computations. More importantly, CPU and OS are almost always combined in fixed proportions: one of each is needed per system (Baseman et.al. 1995)1.
