试画出6个相同设备，通过3个控制器，2个通道实现多通路的连接图。
12二．（12分）有三个程序A 、B 、C ，它们使用同一个设备进行I/O 操作， 并且按照A 、B 、C 的优先次序执行。
这三个程序的计算和I/O 时间如下 表所示。
假设调度的时间可以忽略不计。
（单位：ms ）1. 在早期的操作系统下，上述程序可以在单道环境中运行，单道批处理系统具有____________、 _____________和______________等特征。
（3分）2. 在单道批处理系统中，内存中仅有一道作业，无法充分利用系统中的所有资源，导致系统性能较差，因此诞生了多道程序设计技术，下列属于多道批处理系统的特点的是( )（3分，漏选、错选均不得分）A. 资源利用率高B. 系统吞吐量小C. 平均周转时间长D. 及时性E. 交互性F. 无交互能力 G . 平均周转时间短 H. 系统吞吐量大3.请画出多道、可抢占方式下（假设内存中可同时装下这三道程序），三个程序运行的时间关系图。
(6分)三.（16分）假定系统有3个并发进程In 、Copy 和Out共享缓冲器Buffer1和Buffer2。
进程In负责从输入设备上读信息，每读出一条记录后放到Buffer1中。
进程Copy从缓冲器B1中取出一条记录拷贝后存入Buffer2。
进程Out取出Buffer2中的记录打印输出。
Buffer1和Buffer2每次只能存放一条记录。
要求3个进程协调完成任务，使打印出来的与读入的记录个数、次序完全一样。

楚雄师范学院2011-2012学年第一学期期中考试试卷课程计算机网络考试时间： 120 分钟班级电信2009 姓名学号一、填空题（将正确答案填在横线上，每空1分，共20分）1.网络把许多计算机连接在一起，而因特网则把许多网络连接在一起。
2．分组交换在各路由器存储转发时需要排队，这就会造成一定的时延。
3.协议是控制两个或多个实体进行通信的规则的集合。
4.信号是数据的电气或电磁的表现。
5.时分复用的所有用户在不同的时间占用同样的信道（或频带）宽度。
6.数据链路层协议有许多种，但有三个基本问题则是共同的。
它们分别是封装成帧，透明传输和差错检测。
7网桥一般只适合于用户数不太多的网络（不超过几百个）和通信量不太大的以太网，否则有时还会因广播信息太多而产生网络拥塞，这就是所谓的广播风暴。
8.因特网采用的设计思路是：网络层向上提供简单灵活的，无连接的数据报服务。
9.一个UDP用户数据报的首部的十六进制表示是：06 32 00 45 00.1C E2 17,那么该数据报的目的端口是__0045__。
10.某台计算机上配置的IP地址为192.168. 1.24/26,那么这台计算机所在网络的子网掩码是255.255.255.192。
11.路由器交换的住处是当前路由器所知道全部信息，即自己的路由表。
12.RIP是一种基于距离向量的路由选择协议，是因特网的标准协议，其最大优点就是简单。
13.通信的真正端点并不是主机而是主机中的进程。
互时的层间接口。
15.在IP数据报的首部格式中，源地址所占的长度是 4 字节。
16.某台计算机上配置的IP地址为172.16. 24.24/22,那么这台计算机所在网络的网络号是172.16.24.0。
17．在因特网上进行多播就叫做IP多播，IP多播所传送的分组需要使用多播地址。
18.在因特网中的所有路由器，对目的地址是专网地址（私网地址）的数据报一律不进行转发。
19.网络层是为主机之间提供逻辑通信，而运输层是为应用进程之间提供端到端的逻辑通信。
