流式套接字（SOCK_STREAM），数据报套接字（SOCK_DGRAM）及原始套接字。1.流式套接字提供面向连接、可靠的数据传输服务，数据按字节流、按顺序收发，保证在传输过程中无丢失、无冗余。TCP协议支持该套接字。2.数据报套接字，提供面向无连接的服务，数据收发无序，不能保证数据的准确到达。UDP协议支持该套接字。3.原始套接字原始套接字主要用于一些协议的开发，可以进行比较底层的操作。它功能强大，但是没有上面介绍的两种套接字使用方便，一般的程序也涉及不到原始套接字。

FTP协议是一种基于TCP/IP的文件传输协议，用来在网络中进行文件传输。FTP是TCP/IP的一种具体应用，它工作在OSI模型的第七层，TCP模型的第四层上，即应用层，使用TCP传输而不是UDP，FTP客户在和服务器建立连接前就要经过一个“三次握手”的过程，它带来的意义在于客户与服务器之间的连接是可靠的，而且是面向连接，为数据的传输提供了可靠的保证-FTP protocol is based on TCP/IP file transfer protocol that is used in the network for file transfer. FTP is a TCP/IP to a specific application, it works in the seventh layer of OSI model, TCP model for the fourth layer, namely, the application layer, using TCP transport instead of UDP, FTP client and server must establish a connection before the After a "three-way handshake" process, it brings the significance of the connection between the client and the server is reliable, but also connection-oriented, for data transmission to provide a reliable guarantee for

网络编程课程设计。多线程对话工具小程序。客户端和服务端代码都包含。对网络编程初学者有较为实际的参考价值。程序还有较大完善空间，有待下载者们加强练习。希望对初学者们有一定的帮助哦！
