資源簡介

本文介紹了在Windows 操作系統下基于TCP/IP 協議Socket 套接口的通信機制以及多線程編程知識與技巧，并給出多線程方式實現多用戶與服務端(C/S)并發通信模型的詳細算法，最后展現了用C++編寫的多用戶與服務器通信的應用實例并附有程序。 關鍵詞：Windows；套接字；多線程；并發服務器； Socket 是建立在傳輸層協議（主要是TCP 和UDP）上的一種套接字規范，最初由美國加州Berkley 大學提出，為UNIX 系統開發的網絡通信接口，它定義了兩臺計算機之間通信的規范，socket 屏蔽了底層通信軟件和具體操作系統的差異，使得任何兩臺安裝了TCP 協議軟件和實現了Socket 規范的計算機之間的通信成為可能，Socket 接口是TCP/IP 網絡最為通用的應用接口，也是在Internet 上進行網絡程序應用開發最通用的API[1]，本文介紹了Socket通信的基本機制以及采用多線程技術實現并發通信的基本原理，并給出實例。
