Most couples who get married or decide to live together generally plan to have children. Several years ago, people thought that having big families was common and this was seen as an advantage. That was mainly because children began working at an early age to help provide for the family. But with the changing times and with the cost of living getting higher every single year, having a big family is no longer considered to be a practical option. In fact, more couples consider that they have only one child and some do not have any desire to become parents at all.

However, taken together, women were still more likely to have had three or more children than to have had two children (46% vs. 36%).

In recent years, women were more likely to have had two children than three or more children a trend that was most marked in the most recent period (38% vs. 25% in 1996;

The law defines youthful o(lenders (age 18 or under) as “delinquent” if they commit oflenscs. As for the same oficnscs, the court would consider an adult as a "criminal". “Status offenders" arc juveniles who commit oflenses appropriate only to juveniles, such as truancy Irom school. Here arc a few ideas to help prevent your children from being a delinquent.

Keep your children in school to help prevent delinquency. Minor oflenscs, such as truancy, can lead to more serious oflenscs. Make clear to your children your expectations about their school attendance. Meet with school officials if necessary.

中央电大 《计算机网络(专)》课程作业参考答案

中央广播电视大学计算机网络技术专业(专科) 《计算机网络(专)》课程作业(1) 一、名词解释 1.计算机网络 计算机网络,是指将地理位置不同的具有独立功能的多台计算机及其外部设备,通过通信线路连接起来,在网络操作系统,网络管理软件及网络通信协议的管理和协调下,实现资源共享和信息传递的计算机系统。 2.资源子网 资源子网负责网络数据处理并为网络用户提供网络服务和网络资源,它主要由联网的主机、中断、中断控制器、联网外设等部分组成。 3.通信信道 通信信道就是传输数据的通道。通信信道按照使用传输介质、传输信号的类型及使用的方式可分为有线信道和无线信道模拟信道与数字信道专用信道与公共信道 4.基带传输 在数据通信中,表示计算机而进驻比特序列0和1的数字信号是典型的举行脉冲信号,该矩形脉冲信号的固有频带称为基带,矩形脉冲吸纳好称为基带信号。在数据通信信道中直接传输数据的基带信号的通信方式称为基带传输。 5. IP地址 IP地址标识着网络中一个系统的位置,就像邮寄信件时的收信人地址和发信人地址一样6.地址解析 在使用TCP/IP协议的网络中,一般是通过IP地址来确定主机的位置,IP地址将物理地址隐藏起来。但在实际的屋里通信时,IP地址是不能够被屋里网络锁识别的,使用的仍然是物

理地址。因此,需要在IP地址与物理地址间建立映射关系,这种映射关系叫做地址解析。 7. 网络互联 路由器支持各种局域网和广域网接口,主要用于互联局域网和广域网,实现不同网络互相通信。 8.路由表 为了完成“路由”的工作,在路由器中保存着各种传输路径的相关数据——路由表,宫路由选择是使用。路由表中保持者子网的状态信息、网络路由器的个数和下一个路由器的名字等内容。 二、简答题 1.什么是计算机网络?计算机网络的发展主要经历了哪四代? 计算机网络就是利用同心锁河北和线路将地理位置不同、功能独立的多个计算机系统互联起来并在网络操作系统等软件的支持下实现网络中的资源(硬件资源、软件资源和数据信息资源)共享和信息传递的系统, 第一阶段(从20世纪60年代初到60年代中期)——面向中端的计算机网络 第二阶段(从20世纪60年代中期到20世纪70年代中期)——计算机通信网络 第三阶段(20世纪70年底啊到20世纪90年代)——计算机互联网络 第四阶段(20实际90年代至今)——宽带综合业务数字网(信息高速公路) 2.计算机网络主要由哪几部分组成的? 计算机网络是由网络硬件系统和网络软件系统组成的。 计算机网络的硬件部分主要完成数据处理和数据通信两大功能,由此可以将其分为资源子网和通信子网两部分。 网络软件包括:网络协议、网络通信软件、网络操作系统、网络管理软件和网络应用软件等。 3.何为单工通信、半双工通信和全双工通信?各有何特点? 在单攻通信方式中,信号智能向一个方向传输,任何时候都不能改变信号的传输方向。 在半双工通信方式中,信号可以双向传送,但必须交替进行,在任意时刻智能向一个方向传送。半双工的通信设备必须同时具备发送和接受数据的功能。 在全双工的通信方式中,信号可以同时双向传送数据。
