计算机网络技术学习心得体会.doc

计算机网络技术学习心得体会 21世纪是一个信息经济时代，信息尤为珍贵;信息即为财富，随着信息技术的高速发展并迅速渗透到社会生活的各个方面，计算机日益成为人们学习、工作、生活不可缺少的基本工具， 计算机逐渐的代替了传统的书本、去做为一个信息的载体。为了保护好信息的安全性，所以学好计算机网络技术尤为重要。 算机网络技术是通信技术与计算机技术相结合的产物。计算机网络是按照网络协议，将地球上分散的、独立的计算机相互连接的集合。连接介质可以是电缆、双绞线、光纤、微波、载波或通信卫星。计算机网络具有共享硬件、软件和数据资源的功能，具有对共享数据资源集中处理及管理和维护的能力。 计算机网络可按网络拓扑结构、网络涉辖范围和互联距离、网络数据传输和网络系统的拥有者、不同的服务对象等不同标准进行种类划分。一般按网络范围划分为：（1）局域网（LAN）；（2）城域网（MAN）；（3）广域网（W AN）。局域网的地理范围一般在10千米以内，属于一个部门或一组群体组建的小范围网，例如一个学校、一个单位或一个系统等。广域网涉辖范围大，一般从几十千米至几万千米，例如一个城市，一个国家或洲际网络，此时用于通信的传输装置和介质一般由电信部门提供，能实现较大范围的资源共享。城域网介于LAN和W AN之间，其范围通常覆盖一个城市或地区，距离从几十千米到上百千米。 计算机网络由一组结点和链络组成。网络中的结点有两类：转接

结点和访问结点。通信处理机、集中器和终端控制器等属于转接结点，它们在网络中转接和交换传送信息。主计算机和终端等是访问结点，它们是信息传送的源结点和目标结点。 计算机网络技术实现了资源共享。人们可以在办公室、家里或其他任何地方，访问查询网上的任何资源，极大地提高了工作效率，促进了办公自动化、工厂自动化、家庭自动化的发展。 学好计算机网络技术尤为重要，进入大学以来，我们开展了计算机网络技术课程，我们尽可能的利用好学习时间，尽可能地学习更多的知识和能力，学会创新求变，以适应社会的需要。 知识更新是很快的，只有不断地学习，才能掌握最新的知识。因此，在以后的学习工作中，我还要继续学习、操作，熟练运用这些知识，不断完善和充实自己，争取做一个合格的当代大学生，将来做一名对社会有用的人。 不管是现在还是将来，我觉得每个大学生都应不断地加强学习，不断地给自己充电，才能不断的开拓进取，勇于创新，才不至于被社会淘汰。

计算机网络技术考点个人总结

第一章概述 一、普遍传输技术：（1）广播式链接：广播网络（一对所有，机器选择接收）、多播网络（一对多，）（2）点到点链接：单播（点对点，一对一） 越小，地理位臵局部化的网络倾向于使用广播床书模式，而大的网络通常使用点到点的传输模式。 二、网络分类 按覆盖范围分：局域网（LAN）、城域网(MAN)、广域网(WAN) 广域网由通信子网连接起来的，通信线路和路由器（不包含主机）的集合构成了子网。 按传输媒介分：铜线、双绞线、光纤、无线链路 三、协议 概念：通信双方关于如何进行通信的一种约定，规定对等实体之间所交换的消息或者分组的格式和含义。 三要素：（1）语法用来规定信息格式; (2)语义用来说明通信双方应当怎么做； (3)定时关系详细说明事件的先后顺序。 接口：在每一对相邻层之间是接口，接口定义了下层向上层提供哪些原语操作和服务 服务：某一层向它上一层提供一组原语（操作），定义用户执行哪些操作，但不涉及如何实现。 实体：任何可以发送或接收信息的硬件或软件进程。在许多情况下，实体就是一个特定的软件模块。 网络体系结构：层和协议的集合称为网络体系结构。网络体系结构定义计算机设备和其他设备如何连接在一起以形成一个允许用户共享信息和资源的通信系统 四、面向连接与无连接的服务 面向连接的服务：为了使用面向连接的网络服务，用户首先要建立一个连接，然后使用该链接，最后释放连接，传输数据保持原来的顺序。面向连接的服务是基于电话系统模型的。如：文件传输、报文序列和字流节（远程登录）、数字化的语音 面向无连接的服务：每一条报文都携带了完整的目标地址，每条报文都可以被系统独立的路由，首先发送的报文会先到达（不排除延迟）。基于邮政系统模型。如：不可靠的数据报（电子垃圾邮件）、有确认的数据报（挂号信）、请求—应答（数据库查询） 五、参考模型 OSI参考模型：物理层（为数据链路层提供物理连接，以便透明的传送比特流） 数据链路层（传送以帧为单位的数据，采用差错控制与流量控制） 网络层（控制子网运行过程） 传输层（提供可靠端到端的服务，透明的传送报文） 会话层（会话进程之间的通信，管理数据交换） 表示层（所传递信息的语法和语义） 应用层（最高层，包含各种协议） TCP/IP参考模型：主机至网络层（相当于OSI的数据链路层和物理层） 互联网层（相当于OSI的网络层） 传输层（相当于OSI的传输层） 应用层（相当于OSI的应用层、表示层、会话层） 两模型的比较：OSI的核心：（1）服务；（2）接口；（3）协议 OSI的协议比TCP/IP有更好的隐蔽性，当技术发生变化的时候，OSI协议相对更加容易被替换为新的协议，且OSI更具通用性。协议一定会符合TCP/IP模型，但TCP/IP不适合任何其他的协议栈。OSI模型的网络层同时支持无连接和面向连接的通信，但是传输层上只支持面向连接的通信。TCP/IP的网络层上只有一种模式（即无连接通信），但是在传输层上同时支持两种通信模式。 缺点：

计算机网络技术学习心得体会
