Electronic information engineering is a system engineering based on computer network and other modern technologies, mainly including information collection, information processing, equipment maintenance and system construction. With the continuous development of computer network technology, electronic information engineering has also made breakthrough progress. Computer network technology is mainly used in the information transmission link, information resource sharing link and information remote control link of electronic information engineering, which brings great changes and improvement to people's daily work and life.

Since the 20th century, information and network technology, mainly represented by microelectronics, computer communication and network technology, has progressed and developed rapidly, and its dissemination and application have had a significant impact on economic development and social transformation. Among them, modern computer communication is an emerging discipline that effectively combines modern computer technology and communication technology. It has developed rapidly after experiencing the information revolution, which has greatly changed the daily work and lifestyle of people in modern society, and the changes in communication have also changed. After entering the new era, the conversion stage from analog signal to digitization to communication signal has basically ended. However, in the field of modern digital communication, there is still a lot of room for the advancement and development of electronic computer technology. Many new technologies and new technologies are emerging in an endless stream, which also provides ample room for future development of the industry. This article analyzes the transformation of computer network communication technology based on multi-platform data. First, use literature research methods to analyze the advantages of computer network communication technology in the era of big data. And summarize the problems of computer network general technology, and then use questionnaires based on big data platform to investigate the impact of computer network communication technology changes on people and the failure of computer network communication in life. The result shows that the video upload fails. The occurrence is very high. About 60% of people have experienced video upload failures. There are relatively few failures in hacking and image upload failures. This shows that the solution to the information network security problem in China is still possible, but the video high incidence of upload failures indicates that the speed of computer network communication needs to be strengthened. The direct impact of the reform of computer network technology is that people have more frequent contacts. About 50% of people have more frequent contacts with family and friends after the reform of computer network technology.

The mature development of computer network technology mainly is due to the combination with OSI network model’s feature of continuous software improvement. In the analysis process of software life cycle, improve the practicability of the software. This paper focuses on analyzing the development and application of extensible computer network design system.

This paper describes how railway signaling systems are computerized equipment that are vital for the guarantee of the safe running of trains. Because of the computerization of railway signaling systems, the importance of a networking interface between these pieces of equipment is increasing. Thus, it is important to have a reliable and safe communication link between signaling equipment. Recently, network technologies have been applied in a real-time industrial control system, and also there are several studies applying computer network technology in vital control systems such as railway signaling systems. To deploy these computer network related studies in railway signaling systems, implementation costs, transmitted reliability, safety assurance technique and compatibility etc, are considered. The computer network protocol for railway signaling systems has an important advantage over the widely used Ethernet in terms of deterministic characteristics. This paper proposes computer network technology, especially the Ethernet, for railway signaling systems. The computer network characteristics of real-time industrial control systems and vital railway signaling systems are presented in this paper. This algorithm presented is based on switched Ethernet technology with a redundancy scheme. Also the paper demonstrates the experimental results of the proposed network algorithm.

Convergence is a term that has been gaining increasing attention across the globe. Conceptually situated between technological and socio-cultural domains – as has been intensely debated between the technological and social determinists since the birth of computer mediated communication (CMC) – mobile culture is no exception. It is powered by inter-operable and multi-functional mobile telecommunication technologies, which are also becoming increasingly high functional especially via fixed-mobile convergence, interconnecting fixed and wireless broadband networks. Wide diffusion and convergence of digital communication technologies – wired and wireless – in recent years have resulted in the emergence of two key paradigmatic convergences: between technology and sociality, and between productivity and play. I will first elucidate these convergences; I will then discuss cultural characteristics of specific East Asian cultures, focusing on South Korea, China, and Japan.

Face recognition based on genetic algorithm

With the fast development in computer network and multimedia technology, digital data (such as image, video, audio or text) are stored, transmitted and distributed through internet without any loss or damage of content. Digital image watermarking is use for the protection of digital data from the illegal manipulations. Watermarking not only allow user to access, view and interpret the image but also protects the ownership of the content, as protection is a crucial area. In this paper, a new semi-blind composite image watermarking algorithm based on DWT-SVD that is robust against various attacks is proposed. We obtained four different frequency images using DWT and IDWT transform. Watermark is embedded in high frequency sub-band by modifying the values of Singular Value Decomposition (SVD). Scaling factor is used to improve. Various experimental results demonstrate that proposed algorithm is able to withstand under various attack.

The Computer Networking course commonly taught in mixed mode involving lecture and practical session whereas beside face-to-face theory session, students need to experience hands-on activities in order to appreciate the technology and contents. Nevertheless the abstraction in Computer Networking course such as the complexity in TCP/IP network layering, the connection and configuration of client and server’s framework, differences in static and dynamic IP address configuration had imposed a great challenge for students to understand and grab the main concept of computer networking technology. As such, an approach of using computer network simulation and visualization tool in teaching and learning Computer Networking course is seen beneficial for educators and students. In this research, computer network simulation software of CISCO Packet Tracer was utilized in Computer Networking (MTN3023) course. Students (N=55) were exposed to CISCO Packet Tracer on which they developed Wide Area Network (WAN) that consists of configuration activities of Personal Computer (PC), Servers and Switches according to CISCO standard. Subsequently, student’s feedback and their insight on the effectiveness of CISCO packet Tracer in learning computer networking were probed using questionnaire. All the feedbacks were investigating statistically using SPSS 16.0. From the analysis, the descriptive results shown that all students were agreed (N=32 : Strongly Agree; N=23 : Agree) that CISCO Packet Tracer had successfully help them to understand several key concepts of computer networking and at the same quash some abstractions they faced in the course. In a nutshell, CISCO Packet Tracer as a simulation and visualization tool had been proven to be an effective software in supporting the teaching and learning of computer networking course.
