What are the new network technologies?

Question 1: What technologies does the network technology include? The key technologies of network include network nodes, broadband network system, resource management and task scheduling tools, and visualization tools of application layer. Network nodes are providers of network computing resources, including high-end servers, cluster systems, MPP system large storage devices, databases and so on. Broadband network system is a necessary means to provide high-performance communication in network computing environment. Resource management and task scheduling tools are used to solve key problems such as resource description, organization and management. The task scheduling tool dynamically schedules tasks in the system according to the current system load, thus improving the operating efficiency of the system. Network computing is mainly scientific computing, often accompanied by massive data. If the calculation results are converted into intuitive graphic information, it can help researchers get rid of the difficulty of understanding the data. This requires the development of visual tools that can be transmitted and read in network computing, and provides a friendly user interface.

Question 2: What are the latest network technologies? When 3G communication technology is taking shape, higher technical applications have been developed in the laboratory. Therefore, while people expect the third-generation mobile communication system to bring high-quality services, the latest technology of the fourth-generation mobile communication system is also quietly carried out in the laboratory. So what exactly is 4G communication? Until 2009, people could not accurately define 4G communication. Some people say that the concept of 4G communication comes from other wireless service technologies, from wireless application protocol, global pocket wireless service to 3G. Some people say that 4G communication is a research topic after 20 10. 4G communication is a system in the system, and various wireless technologies can be used. But no matter how people define 4G communication, one thing people can be sure of is that 4G communication may be a more perfect wireless new world than 3G communication, and it can create many applications that consumers can't imagine. The maximum data transmission rate of 4G exceeds 100 Mbit/s, which is 1 10,000 times that of mobile China and 50 times that of 3G mobile China. 4g mobile phones can provide high-performance streaming media content and become personal identification devices through ID applications. It can also accept high-resolution movies and TV programs, thus becoming a link in the new infrastructure combining broadcasting and communication. In addition, some services such as wireless instant connection of 4G will be cheaper than 3G. In addition, 4G is expected to integrate different modes of wireless communication ―― from indoor China networks such as WLAN and Bluetooth, cellular signals, radio and television to satellite communication, and mobile users can roam freely from one standard to another. 4G communication technology is not divorced from the previous communication technology, but based on the traditional communication technology, some new communication technologies are used to continuously improve the efficiency and function of China wireless communication network. If 3G can provide people with a high-speed wireless communication environment, then 4G communication will be an ultra-high-speed wireless China network, an information superhighway without cables. This new China network will enable users in China to connect wirelessly and in three-dimensional virtual reality. Compared with traditional communication technology, the most obvious advantages of 4G communication technology are call quality and data communication speed. However, in terms of call quality, mobile China consumers are still acceptable. With the development and application of technology, the call quality of existing mobile phones in China is still improving. The high speed of data communication is indeed a great advantage, and its maximum data transmission rate reaches 100 Mbit/s, which is incredible. In addition, due to advanced technology, the cost investment is greatly reduced, and the future 4 G communication cost will be lower than that in 2009. 4G communication technology is another evolution of wireless communication technology after the third generation, and its development has a clearer goal: to improve the speed of wireless access of mobile devices to the Internet in China. According to the three-stage development plan of the 3G market, 3G multimedia services will enter the third development stage in 10 years, when the 3G China network covering the whole world has been basically established, and more than 25% of the global population will use the third generation mobile communication system. In developed countries, the penetration rate of 3G services in Chinese mainland is over 0%, so a new generation system is needed to further improve the service quality. In order to make full use of the advanced services brought by 4G communication, people have to rely on various 4G terminals. Many communication operators just saw the huge market potential of future communication, and began to focus on the production of 4G communication terminal products, such as the production of small terminals with high-speed packet communication function, video China terminals equipped with cameras and video transmission services for film and television, or card-type data communication terminals matched with computers. With these communication terminals, people's mobile phone users can roam at will and enjoy high-quality communication anytime and anywhere. China network structure of 4G system and its key technologies The China network structure of 4G mobile system can be divided into three layers: physical China network layer, intermediate environment layer and application China network layer. The physical China network layer provides access and routing functions, which is completed by the combination of wireless and core China. The functions of the intermediate environment layer include QoS mapping, address translation and integrity management. The interface between the physical China network layer and the intermediate environment layer and their application environment is open, which makes it easier to develop and provide new applications and services, provide seamless high data rate wireless services, and run in >:>

Question 7: What are the emerging network technologies in recent two years? First, VR

That is, VR (Virtual Reality) was put forward by jaron lanier, the founder of American VPL company, in the early 1980s. Its specific connotation is: the technology of providing immersion in computer-generated interactive three-dimensional environment by comprehensively utilizing computer graphics system and various interface devices such as reality and control. Among them, the computer-generated interactive three-dimensional environment is called virtual environment (ve for short). Virtual reality technology is a computer simulation system technology that can create and experience virtual worlds. It uses computer to generate simulation environment, uses multi-source information fusion, and makes users immerse themselves in the environment through interactive three-dimensional dynamic scene and entity behavior system simulation.

Second, AR

The synonym ar (augmented reality) generally refers to augmented reality.

Augmented Reality (AR) is a technology to calculate the position and angle of camera images in real time and add corresponding images. The goal of this technology is to put the virtual world in the real world on the screen and interact with it. This technology was put forward by 1990. With the improvement of computing power of portable electronic products, it is expected that augmented reality will be more and more widely used.

Question 9: What are the majors about the Internet? This range is very, very wide. It can be said that any enterprise in reality is related to the Internet.

For example, the control circuits of various mechanical products, in the final analysis, are only microcomputers and various mobile phones, and the Internet is also needed.

You should think about the problem from the angle you like, and it is not a good idea to ask others what is relevant.

If you have a certain foundation, I suggest you study e-commerce, which will be a general direction in the future. Everyone buys things online.
