Mutual and Combined in the Internet Age

The origin of the Internet can be traced back to the hegemony struggle between the United States and the Soviet Union in the last century. At that time, the Soviet Union launched the first human satellite. In order to compete with the Soviet Union, the United States immediately established the Advanced Research Projects Agency (ARPA). Since then, science and technology have been applied to the military and national defense fields.

? The so-called network era refers to the era based on information and communication technology, including computer network, radio and television network and telecommunication network, which has the characteristics of global Internet popularization and prosperity. In the past few decades, the Internet has developed rapidly and has been widely used in various industries, such as financial industry, medical and health industry, agriculture, education and so on. At the same time, it also gave birth to many new industries, such as social media, e-commerce, Internet of Things and so on. A.S. Tannenbaum, the leader of American computer network, believes that the Internet refers to the interaction between independent electronic computers. Compared with traditional media, the Internet has four characteristics:

1, global interactivity. The Internet is open to the whole world and has no boundaries, which is its greatest charm. Technically, the Internet is open to anyone and anywhere. As long as people all over the world have a terminal device and wireless signal or other communication conditions, they can access the network to communicate with others and realize the global transmission of information.

2. Form virtualization and digitization. The things on the Internet are either based on the physical objects that exist objectively in reality, or they are unconstrained. Through imaging technology, it is presented on every shiny square computer screen in the form of pictures and words. It feels like a cold LCD screen, not a real thing. For example, the common balance and change on Alipay and WeChat, as virtual electronic money, what we see in our daily consumption is just a string of numbers, not the traditional paper money that can be perceived. Another example is the characters and objects in online games, which cannot be found in reality.

? 3. Convenient and efficient. Using the Internet to obtain information is much faster than traditional paper media. A large number of information resources can be obtained only by inputting keywords in search engines, which frees people from the burden of rummaging through paper materials. At the same time, based on the global nature of the Internet, an email can be sent from our hands to the other side of the ocean in just a few seconds, saying goodbye to the old life of "slow mail for cars and horses", which is fast and improves efficiency.

? 4. technical. Computers, mobile phones and other electronic terminals are all products of high technology, and the satellite communication or wireless communication they connect can not be separated from the support of high technology. The computing power of information sending or receiving equipment is usually related to the chip integration density of computing equipment, which is a high-tech problem. The stronger the computing power of transmitting or receiving equipment, the faster the speed of processing information and sending and receiving information, which involves dielectric materials and is not a simple problem to solve. In addition, the Internet also involves many aspects, such as secure electronic authentication technology and information encryption technology, which are inseparable from the support of high technology. It can be said that the network era is also a technological era, and whoever is more advanced in technology will have the initiative of the times.
