With the development of reformation on teaching model of the computer networks course, construction of teaching resources is demanded more and more. It stares us in the face that teaching materials curricular or extracurricular; electronic or classic; on-line or off-line are needed to be set up. In this paper, the practice of stereoscopic teaching resources construction is concluded according to the...
With the rapid development of Internet, a number of new resources of IPv6 have emerged. But some local area networks can not use these resources as it does not support the IPv6. So how to achieve communication between IPv4 and IPv6 is a problem to be resolved urgently. Combining NAT-PT with DNS_ALG, this system makes it possible to realize IPv4 and IPv6 communications between applications. Finally,...
Along with the development of network technology, computer assisted instruction (CAI) is transferred from operating on a single computer into sharing on the network. Meanwhile, its exhibition modes are diversified with the improvement of multi-media technology. Nowadays, the instruction based on the network has become a popular teaching model. The network based on computer assisted instruction (NBCAI)...
Through introducing the development and current situation of remote meter reading system at home and abroad, the application of the GPRS wireless communication technology in remote meter reading system was illustrated. Aiming at the key section-network architecture, the network structure of data transmission based on GPRS, several access modes the data center server connecting to Internet, communication...
With the development of reformation on teaching model of the course of computer networks, teaching resources construction is demanded more and more. It stares us in the face that teaching materials curricular or extracurricular; electronic or classic; on-line or out-line are needed to be set up. In this paper, the practice of tridimensional teaching resources construction is concluded according to...
By analyzing the problems encountered by contemporary university students in study, the importance of autonomous learning for students is pointed out. The methods for improving the autonomous learning ability are given. Taking the teaching of Assembly Language and Programming as an example, a network platform for study Assembly Language and Programming is designed to serve as a platform for teacher-student...
With the widespread use of broadband network, the firewall, as a filter installed on the border of network, can easily cause congestion and becomes the bottleneck of network transmission. The Web Monitoring System Based on the URL Analysis introduced in this paper replicates the user Web request by the use of the monitoring technology, extracts and analyzes the URL of user request. Then the URL will...
Aiming at the security requirement of the Intranet that is different from Internet, an security architecture for Intranet is proposed. In physical layer and data link layer, based on network switch the intranet is divided into several parts separated from each other as required. In network layer, making use of the NAT gateway integrated in virtual server the intranet or its part is hidden to ensure...
A simplified embedded experiment platform is designed and implemented to facilitate learners. The platform is powered by a C8051F microprocessor, which is also equipped with a USB interface, a RS-232 interface, two 10-base T Ethernet interfaces, a 4*6 keyboard as well as a 6-bit LED display. Debugging can be achieved through the JTAG interface. Both the RS-232 interface and the Ethernet interfaces...
In order to improve the efficiency of energy utilization in Wireless Sensor Networks (WSN), an energy-balanced clustering routing protocol (EBC) is proposed. In the protocol, the nodes select cluster heads in a distributed way, the signal intensity is used to control the distance between nodes which are in the same cluster, and the nodes with more remaining energy are chosen as the cluster heads....
Assembly Language and Programming is a course highly depending on practice. Practice teaching is an aid for teacher's classroom teaching. The practice teaching of Assembly Language and Programming was studied in the paper. The importance of reasonably arranging experiments for students to understand the contents learnt in the classroom was pointed out first. Then the assignment of the total time for...
In order to meet the needs of monitoring and recording telephone calls and strengthen supervision over safety-production for the control center of organizations, the Web-based VoIP recording management system is developed. This system realizes several management modules, including management of device, channel, call record, recorded files, system setting, and the system auxiliary functions for user...
A screen wall is a widely used application in reality and has been implemented in various methods. Traditional implementation methods always adopt dedicated devices according to specific hardware, which leads to poor portability and limited function. Compared with traditional methods, computer technology conduces to powerful image processing function. Additionally, clearer picture transmission could...
Compared with traditional techniques on identity authentication, fingerprint identification has more advantages owing to its high reliability and accuracy. The thesis describes a fingerprint-based system for the occasion where identity authentication is needed. The system, which could perform the collection, store, comparison of fingerprint, could achieve accurate fingerprint identification.
Aiming at the problems in traditional teaching methods of computer fundamentals course, a series of reform measures are put forward, such as innovating teaching methods, paying attention to cultivate the practical ability of students, and constructing network teaching platform to enrich the teaching resources and enhance the communication between teachers and students. Students can download many resources...
Combined with the characteristics of this course and the authors' teaching experience, a teaching method that seeks to innovate in teaching objective, teaching concept, teaching content, and teaching resources is proposed in this paper after deep consideration into the necessity to conduct teaching reform in the era in which computer networks is highly developed.
In consideration of security and banning minors from Internet bars, there's a need to monitor Internet surfing personnel in Internet bars. Common monitoring systems invariably achieve this goal by installing specialized equipments and dedicated hardware. The monitoring system discussed in this paper takes advantage of the general existing equipments in most Internet bars, i.e. computer's USB cameras,...
Computer Interface Technology is a specialty course about the hardware. The current teaching situation of the undergraduate is analyzed, and the factors that impact teaching quality are pointed out. Then some solutions are given to improve teaching quality.
Mobile agents (MA) are autonomous software entities that are able to migrate across heterogeneous network execution environments, they have wide application prospects. The security issues are becoming obstacles for the application of mobile agents. Compared with host protection, the research of mobile agents active protection is at the beginning stage. Obfuscation is a technique in which the mobile...
In order to alleviate the burden of network administrators in the network resource management field, a network resource management system is designed and implemented based on the design idea of SNMP. This system which based on VC++ platform utilizes the principle of network communication and the feature of network resource, implements management of the IP addresses and the monitoring of the servers,...
