Course Description

This course is a required course for Engineering Master of Computer Science in International Engineering Institute. Computer network is one of the most rapidly developing new technologies in computer science and engineering. It’s also one of the most active areas in computer application. Computer network is a cross subject which is formed by the combination of computer technology and communication technology. With the rapid development of Internet technology, the construction of global information highway is also arising. At present, the network technology has been widely used in the fields of electronic government affairs, electronic commerce, distance education, telemedicine, communication, military, scientific research, information service and so on. This course includes computer network architecture and Internet protocol, which focuses on the data link layer, network layer, and transport layer. Students should understand the whole architecture of computer network and master the basic network principles and developing techniques, which will lay a good foundation for further studying related courses.

Prerequisite

Advanced programming language and designing: owning the basic programming ability.

Structure of computer system: understanding the concepts of instruction system, data representation, addressing mode, interrupt, I/O structure.

Operation system: understanding related knowledge of processing management, memory management, file system, networking and security.

Course Objectives

This course is an important subject to be mastered by the researchers of computer science and technology. Through teaching the theory and practice of the course, students should be able to:

Grasp the computer network basic concept, principle, algorithm and protocol firmly,

Understand the development trend of the computer network ,and to

Master the basic skills of analysis and design a computer network, so that they lay a good foundation for the future related research in this field.
