Introduction of Computer Networks
Computer Networks is a developing subject combining computer and communication technology. In the information age of today, computer networks is acting as a more and more important role, and it has been a technological pillar for the promotion of society development. The course Computer Networks is a compulsory course for the undergraduate in our college. This course systematically and fully introduces the architecture of network, the basis of data communication, OSI reference modal, data switch techniques, LAN, network interworking and TCP/IP protocols, etc. With the leadership of the principal of the course and the other teachers in this group, this course is entitled the “National Superior Course”.
By the study of this course, it aims at enabling the students to systematically understand and grasp the followings:
1. The basic concepts, theory and methods of computer network.
2. The architecture, hierarchy, service and protocols, and topological structure of network.
3. The basis of data communication, encoding, multiplexing, and data switching technology.
4. Sliding window, stream control and congestion control protocols.
5. Route selection strategies, routing algorithm and network interworking technology.
6. LAN technology, CSMA/CD media access controlling method, and the principle of network devices.
7. The principle of TCP/IP protocols, including: IP protocol, ARP protocol, ICMP protocol, IGMP protocol, UDP protocol, TCP protocol, DNS protocol, FTP protocol and HTTP protocol, etc.
All in all, this course aims at fostering the students to grasp the basic theory and practical application knowledge of computer networks, enabling the students to have the primary ability of analysis and design of computer network systems, and promote their comprehensive accomplishment. And it also aims at laying certain theory and working foundation for the students to undertake the research and work in computer networks.
