操作系统讲解-基于图形化的远程讲解系统 ????毕业论文 ???? ???? ???? ???? 基于图形化的远程讲解系统 The Remote Teaching System Based on Graphs Abstract: The concept of Real-time Communication System created which changed the Internet overwhelmingly. Up to now, there are ICQ, MSN, QQ and so on. However, there are some questions about Real-time Communication System. Firstly, only the communication based on literals, files, audio and video is supported, and it lack the tools and environment to draw graphs.Secondly, or can do it, but for transferring too large picture data, the data volume transferred in unit time is larger,and it is not strongly real time. Based on the analysis of status and development trend of Real-time Communication System, aim at above questions on The Remote Teaching System Based on Graphs, This paper brings some solutions: Firstly, it proposes the concept modal of The Remote Teaching System Based on Graphs. Secondly, integrating graphic tools in teaching system helps to draw real-time graphs. Third, transferring graphs’ characters information solves the problem of transfer large data. First, this paper discusses Real-time Communication System status, some questions, and put solution for developing Real-time Communication System based on graphs. Secondly, it discusses theories of graphitic, SOCKET, TCP/IP, the characters and function of The Remote Teaching System Based on Graphs and so on. Lastly, it mainly describes how The Remote Teaching System Based on Graphs is designed and realized. This paper bases on the hypothesis of complex graphs consisting of basic ones. So we need to research on solutions of drawing, coding and transferring instantly graphs.
