某计算机配备了工作集统计装置,操作系统分配进程在内存的页面数量随工作集的大小而浮动。假定工作集窗口的大小为12,即访页序列中连续12次访问页面。系统规定执行每条指令后统计一次工作集大小,每执行5个指令调整一次进程分配内存页面数量,按前5次统计的最大者进行调整。现有一个进程的访页序列:    …26157777516234123444343444113235665462…                                            ↑                                            T    在时刻T,应给该进程分配(23)页面。

  6. Traditional structured analysis techniques focus upon the flow of(71)within a system. Object - oriented analysis emphasizes the building of real - world models. It examines requirements from the perspective of the classes and objects found in the vocabulary of the(72)domain.

  10. A typical(66)language contains an applicative sub-language which approximates the mathematical abstractions of "timeless" functions applied to "spaceless" values, where the actual operation sequences and use of storage space during expression evaluation are organized behind the(67). In this setting, values are data structures of low volume, typically a few computer words or less, which means that an illusion of spacelessness can be realized by having(68)results during expression evalution stored at the discretion of the language implementation, and effecting parameter(69)and(70)operations through value copying.
