A Web-Based Introduction to Computer Networks for Non-Majors

对许多学生来说，深入了解计算机网络的功能越来越重要。作为计算机科学的一个例子，对计算机网络主题的相对深入的处理也是更传统的广度优先方法的一个很好的替代方案。在这个项目中，该部门正在开发课件，提供了一个介绍计算机网络，用于介绍计算机科学课程的学生谁不打算主修计算机科学。该课件使用万维网，由超文本标记语言文档和一组使用Java编程语言的“可执行内容”应用程序组成。Java应用程序使用交互式算法动画来说明关键概念。重点领域包括CSMA/CD、互联网协议路由、TCP错误和流量控制、加密和安全套接字、域名解析和超文本电信协议。每个概念在Web设计中的作用可以作为一个组织主题。重点放在关键概念和动画应用程序，这一材料的显着理解是可能的非专业课程。 课件是公共基础课的重要组成部分。该课程的受众包括广泛的学生，主要是本科生，但也有一些在职教师。职前教师和技术专业的学生占很大比例。了解计算机网络对我们的在职教师和技术专业的重要性是项目设计的主要因素。 该课件可在PC机联网的计算机教室中使用。可以使用Java应用程序的一种情况是在封闭的学生实验室中。

Insight into the functioning of computer networks is of increasing importance for many students. As an illustration of computer science, a relatively in-depth treatment of the topic of computer networks is also an excellent alternative to the more traditional, breadth-first approach. In this project, the department is developing courseware that provides an introduction to computer networks, to be used in an introductory computer science course for students who are not planning on majoring in computer science. The courseware uses the World Wide Web and consists of Hypertext mark-up language documents and a set of `executable content` applications using the Java programming language. The Java applications use interactive algorithm animation to illustrate key concepts. Highlighted areas include CSMA/CD, Internet protocol routing, TCP error and flow control, cryptography and secure sockets, domain name resolution, and Hypertext telecommunications protocol. The role of each concept in the design of the Web can serve as an organizing theme. With a focus on the key concepts and animated applications, a significant understanding of this material is possible in a course for nonmajors. The courseware is a major component of the primary course for nonmajors. The audience of the course includes a broad range of students, primarily undergraduates, but with some in-service teachers. Preservice teachers and technology majors form a large fraction of the students. The importance of understanding computer networks for our preservice and in-service teachers and technology majors is a primary factor in the project design. The courseware can be used in a computer classroom of networked PCs. One situation in which Java applications may be used is in closed student laboratories.
