Chapter s Operating System 5.1.1 Resource allocation and related functions In the latter approach, the Os maintains a common pool of resources and allocates from this pool on a need basis. Thus, OS considers allocation of a resource when a program raises a request for a resource. This approach is called dynamic allocation because the allocation takes place during the execution of a program. Dynamic resource allocation can lead to better utilization of resources because the allocation is made when a program requests a resource. 在后一种分配方式中,操作系统维护一个公共资源池,并按照 程序的需要对资源进行分配。这样,OS只在程序提出对一个资 源的需求时才进行资源分配,这种方式也称为动态分配,因为 分配是在程序执行的过程中进行的。动态存储分配的资源利用 率较高,因为它是在程序需要资源时才进行分配。Chapter 5 Operating System 计算机专业英语 5-11 In the latter approach, the OS maintains a common pool of resources and allocates from this pool on a need basis.
