Network consists of nodes and connections, representing many objects and their relationships. Mathematically, the network is a graph, which is generally considered as a weighted graph. In addition to the mathematical definition, the network also has a specific physical meaning, that is, the network is an abstract model from some practical problems of the same type. In the computer field, the network is a virtual platform for information transmission, reception and sharing. Through it, all kinds of point, surface and body information are linked together, so as to realize the enjoyment of these resources. Network is the most important invention in the history of human development, which has promoted the development of science and technology and human society. Before 1999, the network structure was generally considered to be random. However, it was not until Barabasi and Watts discovered the scale-free and small-world characteristics of the network in 1999 and published their findings in the world-famous journals Science and Nature that people realized the complexity of the network. With the help of text reading, picture viewing, audio and video playback, download and transmission, games, chat and other software tools. The network will bring people extremely rich life and wonderful enjoyment from words, pictures, sounds and videos. Who can tell me what network and communication are and talk about my own understanding?
Network: We often say that the network refers to computer networks, such as the Internet, focusing on connection and enjoyment.
Technology is the communication between computer network layer and application layer: it should be said that information transmission pays attention to physical transmission media, links and information transmission methods.
How to correctly understand the Internet?
Correctly understand the "double-edged sword" of the network, take its essence and discard its dross, and use it as a carrier to derive a variety of information dissemination methods. College students are exposed to an unprecedented vast space through the Internet, and can obtain information, learn knowledge, exchange emotions and understand society more effectively and widely. Behind its positive role, cyberspace lures college students with dizzy colors, which makes some college students fall into the trap of losing themselves. So we need to find the essence in a lot of information. The essence is the information we need and the resources that can help us. Then the first thing to do is to read purposefully according to your own needs. People's energy is limited and can't be spent on useless work.
Adjust the mentality and improve the ability to resist temptation. The internet is just a tool we use, not for fun. College students should enrich their spiritual space and real space, and let themselves have busy places, time and content, such as participating in social practice activities and various forms of campus activities. We can learn about world events by watching news online, expand our knowledge through online competitions, or go to some learning websites to assist in learning. The purpose of surfing the Internet is to adjust the mentality. The study task is heavy and the psychological pressure is great. You can find a bosom friend to chat and relax online. Pay attention to improving students' own quality and ability, and cultivate and improve your self-control. Make yourself the master of the network and make the network a useful learning tool in your hands.
Make good use of the network as a virtual communication platform. The network is also a communication platform. With this platform, we can meet people who are completely impossible in our real life and expand our communication scope. If you have something on your mind, you can talk to friends online, and there is no concern in real life; If you want to improve your foreign language level, you can meet foreigners on the international dating network and communicate directly. If you want to meet alumni, you can go to a special campus website. In a word, the network has greatly expanded our communication. All kinds of people appear on the internet with their favorite faces, and can exchange ideas and opinions with others, and gradually improve the network system of self-knowledge. Through this platform, we can also find many friends to make progress together.
Reasonable arrangement of online time, correct treatment of online entertainment resources, combination of work and rest, and entertaining are the healthy learning methods we advocate. Moderate entertainment can relieve the pressure in study and life, and also provide energy for subsequent study and work. Indulging in online entertainment resources (such as online games and online chats) not only wastes time, but also affects normal work and study. Only by treating online entertainment resources correctly can we really relax from the network and benefit from it. We must arrange surfing time reasonably and strike a balance between surfing the Internet and working and studying. Only by arranging the online time reasonably can we make efficient use of network resources and make them really convenient for work, study and life.
Network has become an inseparable partner of everyone in the new era. Only by being vigilant and improving self-control and judgment can we give full play to the role of the network and make it our most effective assistant.
Network is a double-edged sword. How to understand it?
Dialectical materialism holds that everything is like a double-edged sword, which has both advantages and disadvantages. On the one hand, the network has many advantages, such as understanding current affairs, learning knowledge, communicating with people, and entertainment. Such as convenient and efficient network information and healthy network communication with many benefits;
On the other hand, the network may also cause a lot of harm, indulging in online games, internet addiction, temptation and fraud.
Such as the danger brought by the complexity of the network environment, the network has a greater "lethality" to primary school students with more problems in real life, and the emergence and development of the network has had a great impact on human daily social life.
The original social structure, social action mode and social stratification have all changed under the impact of the network.
What's the difference between people who play the Internet and those who don't?
People who play the Internet will let more people know him, but people who don't play the Internet won't know him. Then people who play the Internet usually deal with people on the Internet.
What is network information?
Network information refers to the sum of all kinds of information resources that can be used through computer networks.
Specifically, it refers to all resources that store various forms of information such as words, images, sounds and animations in the form of electronic data in non-paper media such as light and magnetism, and reproduce them through network communication, computers or terminals.
There are many channels or platforms for publishing network information, such as search engines. Network information flows across borders, and information flow leads technology flow, capital flow and talent flow.
Extended data:
Characteristics of network information:
(1) is valid.
Traditional commercial information, due to slow transmission speed and poor transmission channels, often leads to information acquisition but also fails. Network information can effectively avoid this situation. Because the network information is updated in time and transmitted quickly, as long as the information collector finds the information in time, the effectiveness of the information can be guaranteed.
(2) The rapid growth of network information.
The freedom of the Internet environment makes the release of information not limited to publishing houses, but any government, research institution, university, company, social group and individual can release information on the Internet without restriction.
(3) high precision
The collection of network information is mostly obtained by finding the source of information release through search engines. In this process, the intermediate links of information transmission are reduced, thus reducing the misinformation and change of information and effectively ensuring the accuracy of information.
