Chapter s Operating System 5.1.1 Resource allocation and related functions In the resource partitioning approach, the os decides a priori what resources should be allocated to a user computation. This approach is called static allocation because the allocation is made before the execution of a program starts. Static resource allocation is simple to implement, however, it could lead to suboptimal utilization because the allocation is made on the basis of perceived needs of a program, rather than its actual needs 在资源分区方式中,操作系统预先决定把哪些资源分配给某个 用户计算使用,这种方法也称为静态分配,因为分配是在程序 执行前进行的。静态资源分配易于实现,但由于它不是从程序 的实际需要出发,而是根据程序预先提出的需求来做决定,所 以容易导致系统利用率下降。 5-10Chapter 5 Operating System 计算机专业英语 5-10 In the resource partitioning approach, the OS decides a priori what resources should be allocated to a user computation.
