This course is a fundamental core major course of the majors in science and engineering, which is a basic computer course for college students majored in science and engineering. Through the study of this course, students can have a basic understanding of computer network, understand the current situation and development trend of computer network, master the basic concepts involved in computer network and the basic knowledge of computer network application, understand and master the principle of Internet, and has good skills in various services provided by Internet. Thus, students are able to master the technical principles and comprehensive application of computer network. This course cultivates students' thinking ability and practical ability, which provides technical and application support for students to learn follow-up courses and to solve related problems encountered in life and work.

Objective 1:

Let students understand the concept of computer network architecture, and master the functions and working principles of each layer in TCP/IP architecture so that students can analyze and solve network engineering problems.

Objective 2:

Let students master the data communication, data exchange and network interconnection technologies involved in the computer communication and network. Let students can carry out networking planning and configuration and have the ability to design research schemes for network problems.

1. Logical operation: It is necessary to learn some basic logical operations in advance, such as ‘and’, ‘or’, ‘not’, and ‘XOR’, which will be used in Chapter 3 and Chapter 5 of this course.

2. The numerical system in computer: It is necessary to learn the number representations for different bases in microcomputer system in advance, such as binary, decimal and hexadecimal.

3. Base conversion: It is necessary to learn the conversion between binary and hexadecimal, binary and decimal, hexadecimal and decimal in advance. Especially, the conversion between a 8-bit binary and a decimal digit within 0-255 is very important.

Q1: Is this course the same as the H3C routing and switching technology course?

A1: It is not quite the same. The course you mentioned focuses on routing and switching technology with emphasis on practice. However, our course is similar to computer network, which is with both theory and practice.

Q2: What's the difference between the computer network course and this course? I feel that the contents of the two courses are similar. What is the difference?

A2: The courses related to network are almost the same. Compared with the computer network course, our course has less content and is a little bit easier. Specifically, our course does not involve the point-to-point channel on data link layer. In addition, network management and network security have not been involved. Generally, our course is more application oriented.

Q3: What are the preliminaries for learning this course? Can a student of non-computer major learn it?

A3: It doesn't need too much preliminaries. We will also provide the preparatory knowledge of this course in the slides for you to choose to learn according to your own needs. In addition, this course is a major basic course for students of non-computer majors in our university.

Q4: How do teachers and students communicate in this course?

A4: During learning, you can ask questions in the course forum at any time. We will seriously take every question you post in the course Discussion Forum and give a reply.
