What is an information-based campus environment?
Related concepts: Campus network is a computer network that provides resources, information exchange and collaborative work for school teaching, scientific research and management under the guidance of certain educational ideas and theories. In China, the construction of campus network has developed rapidly in recent years. Up to now, nearly 6,000 schools across the country have built primary and secondary school campus networks. They provide a good example for realizing the sharing of educational resources, information exchange and collaborative work in primary and secondary schools in China. However, with the rapid increase of the number of campus networks in various parts of China, there is an increasing demand for how to realize the sharing of educational resources, information exchange and collaborative work between campus networks. Specific analysis: With the development of society, the computer network on campus has become the infrastructure and necessary condition for running a school. In order to make full use of modern information technology, based on the existing computer network of education and scientific research in China, we will promote the reform and development of adult education in various vocational colleges and improve the quality of education. In order to clarify the principles, requirements and implementation plan of the construction of vocational education campus network, we put forward the following Standards for the Construction of Vocational Education Campus Network, which can provide reference for schools that have built or are building vocational education campus network. First, the overall principle is based on China's national conditions, considering the needs and possibilities of the school, taking meeting the needs of teaching and management as the starting point of campus network construction, making full use of modern information technology, making overall plans, promoting demand, adapting to local conditions and developing step by step; According to the national development plan of modern distance education, make full use of the digital, multimedia and interactive modern education platform based on China Education and Research Computer Network and China Education TV Station; Under the guidance of modern education theory, we can consider cooperating with universities with mature experience in online education and distance education, fully mobilize the enthusiasm of all parties, work together, develop independently, cooperate and tap the potential, actively introduce various media teaching resources, and establish a teaching resource database for Shanghai vocational education; Second, the campus network Campus network is a broadband multimedia network that provides teaching, management, scientific research and comprehensive information services for schools. First of all, the campus network should provide an advanced information teaching environment for the school's teaching, management and scientific research, so the campus network is a broadband, interactive and professional local area network. Teaching management system, multimedia classroom, educational video-on-demand system, electronic reading room, teaching and examination database, etc. Can work through the network. The campus network should also meet the communication requirements inside and outside the school. Including Internet service, distance education service, data broadcast information download, video conference and IC card service. Network construction should follow the principle of "based on demand, overall planning, step-by-step implementation, maturity and reliability". The campus network construction scheme should conform to the long-term development plan of the school, and the infrastructure construction, teaching and management software construction and personnel training should be planned as a whole. When building a campus network, according to the funding situation, it can be done in one step, or it can be planned as a whole, implemented step by step and gradually put in place. Third, the construction of campus network requires practicality. Campus network must have the functions of teaching, management, scientific research and communication. The technical system design should consider the technical development in 3-5 years, and the network equipment should be highly universal, compatible and extensible, and can support teaching software with different storage formats. Security has powerful functions such as preventing system data loss, anti-virus measures and information filtering. Friendly user interface, easy to use, simple to operate, online help. Reasonable economic investment and long service period. Four, the campus network facilities to meet the basic requirements of campus network construction, need to have the corresponding software and hardware support. Network equipment Campus network equipment mainly includes integrated wiring, servers, switching equipment and user terminals. (1) The physical layer of the integrated wiring campus network should be designed according to relevant specifications and standards. The backbone rate of the campus network can be gigabit (optical fiber can be used if possible), and the backbone network is not lower than the level of "100M fast Ethernet". (2) server hardware: it should be equipped with a safe, stable and reliable dedicated server (domestic brand server is recommended) with capacity and I. ......
What is a campus network?
Campus network is a computer network that provides resource sharing, information exchange and collaborative work for school teaching, scientific research and management under the guidance of certain educational ideas and theories. In China, the construction of campus network has developed rapidly in recent years. Up to now, nearly 6,000 schools across the country have built primary and secondary school campus networks. They provide a good example for realizing the sharing of educational resources, information exchange and collaborative work in primary and secondary schools in China. However, with the rapid increase of the number of campus networks in various parts of China, there is an increasing demand for how to realize the sharing of educational resources, information exchange and collaborative work between campus networks. The design goal of campus network is to connect the information resources of different applications with each other through high-performance network equipment, to form a 12000/xpranet system in the campus area, and to access the WAN through routing equipment. Carry out the overall design of campus network: first, carry out object research and demand investigation, make clear the nature and tasks of the school, the needs and conditions of the main system construction of reform and development, and accurately describe the information environment of the school; Secondly, on the basis of applying luxury analysis, determine the service type of the school 12000/xpranet, and then determine the objectives of system construction, including network facilities, site setting, development, application and management; Thirdly, the topological structure and function of the network are determined, and the system analysis and design are carried out according to the application requirements, construction objectives and the distribution characteristics of the main buildings in the school; Fourthly, determine the principle requirements of technical design, such as the standards and requirements of technical selection, wiring design, equipment selection and software configuration; Fifth, plan the implementation steps of campus network construction. The scientific nature of the overall design scheme of campus network should be reflected in whether it can meet the following basic requirements: (1) overall planning arrangement; (2) the combination of advancement, openness and standardization; (3) reasonable structure and easy maintenance; (4) efficient and practical; (5) Support broadband multimedia services; (6) Fast information exchange, cooperative work and image display can be realized. With the development of economy and the implementation of the national strategy of rejuvenating the country through science and education, the construction of campus network has gradually become a basic construction project of a school and an important symbol to measure the informationization and modernization of a school's education. At present, most qualified schools have completed the hardware construction of campus network. Then, for many years, the understanding of campus network is not comprehensive enough, and there are even great misunderstandings. For example, the higher the network construction, the better, the blind pursuit of high investment in construction, the lack of comprehensive planning, development and application of campus network construction; It is considered that the completion of campus network and access to the Internet are equivalent to the automation and informatization of teaching and office, but there is a lack of comprehensive management of campus network, application training of technicians and teachers, and development and accumulation of teaching resources. All these have greatly hindered the practical benefits that campus network should play in school management, education and teaching. Generally speaking, the campus network is a broadband multimedia network that provides teaching, scientific research and comprehensive information services for school teachers and students. First of all, the campus network should provide an advanced information-based teaching environment for school teaching and scientific research. This requires the campus network to be a broadband, interactive and professional local area network. Multimedia teaching software development platform, multimedia demonstration classroom, teacher preparation system, electronic reading room and teaching test database can all run on this network.
What is 30 points of school informatization?
In recent years, modern information technology has been widely used in all fields of school education, and educational informatization is entering a period of rapid development. Due to the attention of * * *, the speed of hardware construction in some schools exceeds the speed of software construction. Every teacher has a laptop that he dreams of, and every classroom has a multimedia teaching platform. From a single classroom to the establishment of a complete campus network, and the rapid rise of metropolitan education network, this trend makes the subject of educational informatization put on the important agenda of school development.
Professor Zhu Zhiting of East China Normal University believes that education informatization should be regarded as a process, and its main feature is the wide application of modern information technology based on computer multimedia and network communication in the education process. This paper attempts to expound the characteristics and corresponding measures of each stage in the process of educational informatization from the perspective of practice, focusing on concepts, literacy and methods, so as to provide more powerful arguments for formulating practical informatization implementation plans.
First, the preparation of informatization
The preparation stage of modern education informatization is based on hardware construction, with the formation of modern educational ideas and the gradual presentation of informatization teaching as the main features. In this process, the school constantly improved teaching methods and advocated the integration of information technology and subject teaching, and multimedia technology began to show powerful functions and charm in the classroom. Although computer multimedia technology can not be widely used in the teaching process, local information teaching has laid the foundation for educational information from the following aspects with brand-new means and conditions:
● Offering information technology courses. Including: the construction and management of computer room; Set up a computer section; Learn to learn, cooperative learning, and explore innovative curriculum goals and concepts; Research and practice of teaching methods and means in information technology classroom: preliminary exploration of subject evaluation. Limited by the social and economic development, the current information technology teaching does not fully consider the actual needs of teaching informatization, and information technology has not quickly become a tool to acquire knowledge. The students are studying for the future.
● Local information teaching. Experts have not reached a unified conclusion about the concept of information-based teaching. More front-line teachers tend to use information-based teaching (partially) as a "means" to enhance students' interest in learning and improve classroom efficiency through the "utilization" of multimedia technology. During this period, the construction and management of audio-visual classrooms are the key points. Teachers mainly hold seminars here, accumulating and popularizing a lot of information-based teaching experience. At the same time, with the acceleration of the whole social informatization process, the school has also made progress in website construction and electronic lesson preparation, and the construction of comprehensive monitoring room has been strengthened. Through the interconnection with metropolitan education network, the ability of the school to obtain external information and strengthen information exchange has been greatly improved.
Teacher training. After the establishment of the school computer department, professional computer teachers gradually replaced amateur computer teachers. The Audio-visual Education Group, with computer major as the backbone, has made great efforts in school-based training. At the seminar, they let other teachers "see is believing", vigorously advocated the application of computer-based multimedia technology, took the lead in integrating schools into the information society, and formed the concept of educational informatization. In the form of "training courses", most teachers will gradually reach the current "intermediate" level of the country, that is, they will be able to master general teaching application software and have the ability to acquire, analyze and process information. However, due to the lag of hardware construction, most teachers take the "intermediate" certificate as the basis for evaluating their professional titles, and because they can't apply what they have learned quickly, they lead to repeated training.
● Step-by-step construction, step by step. Due to the advocacy of the state, the school has made every effort to strengthen the construction of information infrastructure with limited financial resources. Before the network hardware construction is completed, our work can't be called information implementation in a complete sense. Realizing the slow enjoyment of information and knowledge by mobile disks can only be called mechanization. This difficult exploration objectively forced the school to form a sense of being ahead of the times. In order to avoid redundant construction and make full use of and develop limited resources, we must seek theoretical and technical support. In this way, in order to meet the spring of education informatization and make the campus network play the greatest benefit from the beginning, it has initially possessed the information-oriented consciousness, network management talents and information implementation ability.
Second, implement informatization.
The completion of campus network is a sign that information engineering has entered the development period. In addition to the campus network, the broadcasting system, communication system and electronic reading system in the school must also be available in order to form a systematic project of information infrastructure. For the school, this systematic project will gradually change the meaning of the traditional campus, and teachers can go to the collective preparation room. ......
What is the campus V network package?
V-network refers to the business of combining mobile phones within the company into a network and providing preferential calls among network members in a certain area (non-roaming state). The number of V network is 4 digits, which generally adopts the last four digits of existing mobile phones. The call charge of V network is: calling party 1 angle/minute, and called party is free. Joining the V network will not affect the original communication of the original number, including the original charging standard.
What information should I pay attention to when looking for a school?
The nature of the school, faculty, liberal arts bias, whether it is "Project 2 1 1" or "Project 985", the number of students, etc. I suggest you check an article in Baidu, the date is June 9, and enter the keyword "University volunteers to fill in Sichuan", which is very detailed.
The campus network has 1000 information points. What level of switch or router should be used in the core layer and what is the price? It is connected to a 10 Gigabit network.
Total bandwidth requirement = 8000 *120 * 2 * 8 =15.36 Gbps.
If you have m gigabit fiber ports and n 100 megabit RJ45 ports, in full duplex mode, the backplane bandwidth is calculated as follows:
(1000 m+100 N) *2 Mbps
In addition, add redundancy and expansion to get the actual backplane bandwidth of the device!
The choice of specific model is closely related to your capital budget. The larger the initial serial number of general equipment, the more difficult it is and the higher the price!
For example, 6xxxxx series and so on!
How to calculate the number of nodes in campus network
Information point, of course. The number of computers connected to the network is indispensable at any time.
If you mean the number of information points, it depends on how many computers will be connected to the network and how many computers will be connected to the network in the future.
