Chapter s Operating System 5.3 OS Structure os design strongly depends on two factors: architectural features of the computer on which it operates, and features of ts application domain Dependence on architectural features is caused by the need to exercise complete control over all functional units of the system. Hence, the os needs to know the addressing structure, interrupt structure, IO organization and memory protection features of the computer system. 操作系统的设计主要基于以下两个因素:它所操作的计算机的 结构特征及它的应用域特征。对结构特征的依赖是由对系统的 所有功能单位进行完全控制的需要而产生的。因此,操作系统 需要了解计算机系统的地址结构、中断结构、IO体系结构及 存储器保护特性。 《什第机专出美语 5-35Chapter 5 Operating System 计算机专业英语 5-35 OS design strongly depends on two factors: architectural features of the computer on which it operates, and features of its application domain.
