Chapter s Operating System 5.3 OS Structure Os policies typically depend on its application domain. For example, the CPU scheduling policy depends on whether the OS will be used for time sharing, or for real time applications. The dependence on these two factors poses obvious difficulties in using an OS on computers with different architectures and different application domains. 操作系统的策略通常由它的应用域决定:例如,CPU的调度策 略是由操作系统是用于分时应用还是实时应用来决定。对这两 方面因素的依赖导致在不同应用域中的不同结构的计算机上使 用同一操作系统的巨大困难。 《什第机专出美语 5-36Chapter 5 Operating System 计算机专业英语 5-36 OS policies typically depend on its application domain.
