●小王需要从①地开车到⑦地，可供选择的路线如下图所示。图中，各条箭线表示路

段及其行驶方向，箭线旁标注的数字表示该路段的拥堵率（描述堵车的情况，即堵车概率）。拥堵率=1-畅通率，拥堵率=0时表示完全畅通，拥堵率=1时表示无法行驶。根据该图，小主选择拥堵情况最少（畅通情况最好）的路线是（70）。

B.①②③④⑥⑦

C.①②③⑤⑦

D.①②④⑥⑦

●he objective of （71）is to determine what parts of the application software

will be assigned to what hardware.The major software components of the system being developed have to be identified and then allocated to the various hardware components on which the system will operate. All software systems can be divided into four basic functions. The first is（72）. Most information systems require data to be stored and retrieved,whether a small file,such as a memo produced by a word processor,or a large database,such as one that stores an organization’s accounting records. The second function is the （73）,the processing required to access data,which often

means database queries in Structured Query Language. The third function is the （74）,which is the logic documented in the DFDs,use cases,and functional requirements.The fourth function is the presentation logic,the display of information to the user and the acceptance of the user’s commands.The three primary hardware components of a system are （75）.
