The emergence and improvement of the Internet have had a tremendous impact on human society, such as: Website Design It can give people a sense of visual impact and information transmission; Online shopping can give people a sense of entity, and the transmission of information and so on. The Internet can quickly provide necessary information for your decision-making, find the treasures in the Library of Congress, which has the largest collection of books in the world, appreciate the rare treasures in the collections of famous museums in the world, understand the weather forecast in a certain region of the world, exchange views and opinions with people with your interests, and obtain employment information, Get very useful computer software for free, exchange emails with friends far away, and order the goods you need online

The information superhighway represented by the Internet is similar to the other two popular media we are familiar with radio, television and radio stations in that they can provide information services to users. For the two information service modes of radio, television and radio, users are basically in a passive position. Users can only passively choose what programs to broadcast in radio, television and radio. However, the information services provided by the Internet are quite different in content and mode. It can not only provide text, images, sounds, but also a large number of numerical data, computer programs, etc. The biggest difference is that users are always in the active position in the entire information service process. Users can roam the entire Internet information space as needed, In other words, you can decide where you want to go and what information you want to get on the information highway. This is one of the reasons why the Internet has become the most popular media and developed so fast.

Since the Internet is so powerful and has so many advantages, curiosity will surely drive people to wonder what the Internet is? How does it work? The Internet is a huge one. A loose collection of computer networks in different countries and regions that are interconnected and communicate with each other. First of all, people must understand that the Internet is not a simple network, but a "super network" composed of different computer networks. A computer network is like a well-known spider web, where information can flow between computers. In addition, there is no mandatory central administrative agency in the world to uniformly manage the operation of the Internet.

From a macro perspective, the Internet should be composed of the following three basic elements: hardware, software and communication network. Here, hardware mainly refers to computers and other relevant equipment that can be seen and touched. Computers include mainframe supercomputers, small and medium-sized computers, microcomputers, notebook computers, etc. The software includes a large number of computer operating systems, network protocols, data, user interfaces and communication software. The communication network can be a modern communication line system consisting of a section of copper wire, double lines, telephone lines, coaxial cables and satellites. Of course, if advanced optical fiber communication lines are used, the information transmission capacity of the network will be hundreds of times higher than the traditional copper transmission capacity.

Here is the simplest connection to introduce the working principle of the Internet: Generally, a practical network can carry thousands of computers. To simplify the situation, consider the most basic situation: there are only two computers on this network. To transmit the information of computer A to computer B, each computer must be equipped with a modem in addition to a communication line connecting the two computers. Modem is essential for information exchange between different computers. Modem includes modulation and demodulation functions. When information is sent from computer A to computer B, computer A must be equipped with a modulator, which translates the digital signal through the computer serial interface into an analog signal, and transmits the translated analog signal to computer B through the communication line. Computer B cannot directly accept analog signals from communication lines. Therefore, before entering computer B, the signal must be processed by the demodulator to restore the analog signal to a digital signal, and then accepted by computer B.

We know that the flow of information between computers is not unilateral, that is, it is not always sent by one computer to another computer. In addition to receiving information, another computer may also send information. In this way, the information converter on the computer communication interface is required to have dual functions of modulation and demodulation.

When information is transferred between different computers, there is a problem of standard code for information exchange, otherwise the transferred information cannot be correctly recognized and processed by computers. It's like people using the telephone to communicate. A Chinese and an American do not understand each other's language. When one party picks up the phone and dials the other party's phone number, although the other party can hear the voice sent, it cannot understand the other party's intention. The same is true for computers. The information inside the computer is represented in the form of 0 and 1, and the computer uses one bit to represent these two states. For English. The standard information standard code ASCII uses eight digits to represent a character. The ASCII set defines English upper and lower case letters, numbers, punctuation marks and other special symbols, plus computer control characters. For our own language and characters, China has also formulated corresponding Chinese character information exchange standards. It is worth pointing out that because of the particularity of Chinese characters in China, A Chinese character must be represented by 16 bits, that is, two bytes represent a Chinese character, and one byte is eight bits.
