网络程序设计_socket_复习题_考点_知识点

Winsock是什么?• Windows下网络编程的规范• Windows下得到广泛应用的、开放的、支持多种协议的网络编程接口。
• 已成为Windows网络编程的事实上的标准。
Windows socket规范• Windows Socket规范本意在于提供给应用程序开发者一套简单的API,并让各家网络软件供应商共同遵守。
Socket原理• Socket通常称为套接字、套管、插口,是两个程序间通信链路的端点。
• Socket实际上是一个编程接口,为网络应用程序提供各种接口函数。
Winsock基本概念• 多数网络协议都由软件实现,而且几乎所有计算机系统都将网络协议的实现作为操作系统的一部分,操作系统提供给用户的程序接口叫做应用程序编程接口(API )。
• 套接字接口(Socket Interface)就是一种API套接字及类型• 套接字(socket)是网络通信的基本构件,是可以被命名和寻址的通信端点,使用中的每一个套接字都有其类型和与之相连的进程。
• 套接字存在于通信区域中,通信区域也称地址族• 套接字通常只与同一区域中的套接字交换数据(也可跨区域通信,但要执行某种转换进程之后才能实现)。
• TCP/IP的socket提供三种类型的套接字:流式套接字(SOCK_STREAM)• 提供一个面向连接的、可靠的数据传输服务,• 内设流量控制,避免数据流超限;数据被看作是字节流,无长度限制。
• 文件传输协议(FTP)即使用流式套接字。
数据报式套接字(SOCK_DGRAM)• 提供一个无连接服务。
• 数据报以独立包形式被发送,不提供无错保证,数据可能丢失或重复,且接收顺序混乱。
• 网络文件系统(NFS)使用数据报式套接字。
原始式套接字(SOCK_RAW)• 该接口允许对较低层协议,如IP、ICMP直接访问。
• 常用于检验新的协议实现或访问现有服务中配置的新设备。
• 服务方式面向连接(虚电路)• 面向连接服务是电话系统服务模式的抽象,每一次完整的数据传输都要经过建立连接、使用连接、终止连接的过程。

sock的知识点总结
1. Sock 的概念和作用
Sock 是 Socket 的简称,它是在网络编程中非常重要的概念,它提供了一种通信机制,使得计算机之间可以进行数据交换。
Sock 的主要作用包括:建立连接、传输数据、断开连接等。
它为应用层提供了数据传输的能力,同时也可以实现基于 TCP 或 UDP 的各种协议。
2. Sock 的类型
Sock 可分为两种类型,分别是面向连接的 Socket 和面向无连接的 Socket。
面向连接的Socket 是指通过建立连接来进行数据传输,它使用 TCP 协议进行通信;而面向无连接的Socket 是指不需要事先建立连接,可以直接进行数据传输,它使用 UDP 协议进行通信。
面向连接的 Socket 保证了数据的可靠传输,但是会有一定的延迟;而面向无连接的Socket 则具有高效的特点,但是不保证数据的可靠性。
3. Sock 的地址
在网络通信中,Sock 的地址包括主机地址和端口号。
主机地址用来标识网络中的计算机,而端口号则用来标识计算机上的不同进程。
主机地址和端口号组合在一起,就可以唯一确定一台计算机上的一个进程。
在建立 Sock 连接时,需要指定对方的主机地址和端口号,以便进行通信。
4. Sock 的创建和使用
在编程中,要使用 Sock 进行网络通信,需要经过一系列的步骤来创建和使用 Sock。
首先需要创建一个 Sock,然后绑定地址和端口号,接着监听连接请求或者发起连接请求,最后进行数据传输和断开连接。
在 C 语言中,可以使用 socket() 函数来创建 Sock,bind() 函数来绑定地址和端口号,listen() 函数来监听连接请求,accept() 函数来接受连接请求,connect() 函数来发起连接请求,send() 函数和recv() 函数来进行数据传输,close() 函数来断开连接。
5. Sock 的通信模式
Sock 的通信模式包括客户端-服务端模式和对等通信模式。
在客户端-服务端模式中,一个程序作为服务端创建 Sock,另一个程序作为客户端发起连接请求,然后进行数据传输;在对等通信模式中,两个程序都创建 Sock,然后互相发起连接请求,进行数据交换。
在客户端-服务端模式中,通常服务端会先创建 Sock 并绑定地址和端口号,然后监听连接请求,客户端再发起连接请求,进行数据传输;在对等通信模式中,双方都可以创建 Sock 并绑定地址和端口号,然后互相发起连接请求,进行数据交换。
6. Sock 的阻塞和非阻塞
Sock 操作可以是阻塞的,也可以是非阻塞的。
阻塞的 Sock 操作指的是执行该操作时,如
果没有数据到达或者连接未建立,该操作会一直等待直到完成;非阻塞的 Sock 操作指的
是执行该操作时,如果没有数据到达或者连接未建立,该操作会立即返回,不会阻塞线程。
在使用 Sock 进行数据传输时,可以设置 Sock 为阻塞模式或非阻塞模式,根据具体需求来
选择合适的模式。
7. Sock 编程的注意事项
在进行 Sock 编程时需要注意一些重要事项,例如网络连接的建立和断开、数据传输的可
靠性和效率、网络协议的选择等。
对于网络连接的建立和断开,需要合理处理连接请求和
断开请求,以避免资源浪费和连接泄露。
对于数据传输的可靠性和效率,需要根据实际需
求选择合适的协议和模式。
对于网络协议的选择,需要根据具体应用来选择 TCP 或 UDP,以满足实际需求。
8. Sock 的应用场景
Sock 在网络编程中有着广泛的应用场景,它可以用来实现各种网络通信功能。
例如,可以用 Sock 实现网络服务器和客户端之间的通信,实现即时通讯软件、网络游戏、数据传输
等功能。
同时,Sock 也可以用来实现网络爬虫、HTTP 服务器、FTP 服务器等网络应用。
除了上述应用场景外,Sock 还可以用来实现网络监控、远程控制、文件传输等功能。
总之,Sock 在网络编程中具有非常重要的作用,它是实现各种网络通信功能的核心技术之一。
9. Sock 的发展趋势
随着互联网的快速发展和网络技术的不断更新,Sock 技术也在不断进化。
未来,Sock 技
术将继续发展,以适应新的网络环境和应用需求。
例如,随着移动互联网的普及,Sock 技术将更加注重移动性和可靠性;随着物联网的发展,Sock 技术将更加注重低功耗和高效率。
另外,随着网络安全和隐私保护的重要性日益凸显,Sock 技术也将更加注重安全性和加密性。
总之,未来的 Sock 技术将更加智能化、安全化和多样化,以满足未来网络应用的需求。
以上就是关于 Sock 的知识点总结,希望能够对大家理解 Sock 技术有所帮助。
Sock 作为网
络编程中的核心技术,具有着非常重要的作用,它是实现各种网络通信功能的基础。
同时,Sock 技术也在不断发展,以适应新的网络环境和应用需求,未来的 Sock 技术将更加智能化、安全化和多样化,为网络通信提供更加强大的支持。
