Even in many cases, the computer can completely replace the traditional letter. Coupled with the application of computers in multimedia, it also makes the relatively mechanical television too monotonous. In short, the modern society, the rapid development of the network for the popularization of the computer provides a very important external conditions. Network television, film and television, network communication, chat, online shopping, etc., the computer is gradually deepening people's daily lives.
1. Industry and commerce
Industry and commerce is one of the earlier areas of the application of computers, and now most of the companies in the world have a strong dependence on computers, because they rely on computer systems to maintain their normal operation.
In the banking industry, the latest application of computers and networks is online banking, which allows banks to provide financial services to their customers via the Internet. Theoretically, customers can enjoy the banking services they need through their computers at the click of a mouse, wherever they are and whenever they want.
In the commercial field, retail stores not only use computers to manage the sales of goods and inventory to provide managers with the best decisions, but also realize e-commerce, which is the use of computers and the Internet to conduct business activities.
In the manufacturing field, all types of products, from bread to spacecraft, can be computer-designed. Computer-designed graphics can be three-dimensional and can be freely rotated on the screen to represent the design from different angles, clearly showing all the individual parts. Computers can also be used in production equipment to achieve complete automation from design to production.
2. Education
Early computer-aided education was very mechanical. Usually the computer displayed a question on the screen and asked the student to enter or select the answer. Obviously, this kind of software cannot stimulate students' creativity and imagination, and it is easy to get bored. With the widespread use of multimedia technology, educational software is not only text and graphics so simple, but also includes music, voice, three-dimensional animation and video. Some software uses real people to pronounce words, which allows students to be more engaged in practicing language pronunciation. Some software uses simulation technology to try to reproduce certain things in the real world on the screen, such as allowing medical students to conduct human anatomy experiments on the computer. The development of computer-assisted education not only makes a fundamental change in school education, but also enables students to experience the application of computers in school, so that students firmly establish computer awareness, which contributes to the cultivation of cross-century, complex talents.
Computers in the field of education to get another important application is distance education. Today's network technology and communication technology has been able to establish a rapid two-way communication between different nodes, so that students can ask teachers questions at home, and teachers can respond to students in a timely manner. Currently, many university students have set up online colleges for distance learning.
3. Pharmaceuticals
The use of computers in the pharmaceutical industry is very common. Hospitals use computers to manage day-to-day affairs, such as electronic medical records, electronic prescriptions, etc. Medical equipment for various purposes is also automatically controlled by computing. In the field of medicine, another important use of computers is medical imaging, he can help doctors clearly see the patient's body, without damaging the patient's body. Computed tomography is the process of irradiating a patient with X-rays from different angles, obtaining a series of two-dimensional images of the organs in the body, and finally generating a realistic three-dimensional structure. Magnetic resonance imaging measures the radio waves emitted by chemical elements in the body, and computerized signals are converted into a two-dimensional image to produce a three-dimensional scene. What has evolved with the Internet is the technology of remote diagnosis and treatment. A hospital in a remote place may have neither advanced equipment nor specialists. The use of remote consultation system, a Shanghai expert can be based on the images and information transmitted to the local hospital for consultation on difficult cases, and even guide the local doctors to complete the operation. This remote consultation system allows patients to avoid the pain of long-distance travel, and can receive timely advice from experts, so as not to miss the opportunity for treatment.
4. Government
The government is undoubtedly the largest user of computers. Many government departments have been using computers to manage their daily operations and automate their offices. In order to adapt to the realization of the demand for information construction and to meet the challenges of the information age, the knowledge economy, and improve the efficiency of the government's business, the government has begun to go online, in the near future people will see a new government - e-government.
The so-called e-government, that is, the establishment of a virtual government on the Internet to realize the functions of the government. Where offline government functions can be realized, basically online should be realized. After the government affairs on the Internet, can be open to the public on the Internet to the government departments of the relevant information, files, daily activities and so on. On the Internet to establish a bridge of communication between the government and the public, for the public and the government departments to contact to provide convenience, and on the Internet traveling to the government's democratic supervision power. At the same time, the public can also complete various government-related tasks such as tax payment and project approval online. Within the government, various departments can also contact each other through the Internet, and leaders at all levels can also make instructions to the relevant departments on the Internet to guide the work of various departments and organizations.
5. Entertainment
Computer games are no longer as simple as the early chess games, but are multimedia network games. Far away from the players can put themselves in a virtual reality, through the Internet can play with each other, in virtual reality, the game through special equipment for players to create an immersive feeling, and even some games also require special goggles and helmets, will be three-dimensional image of the presentation in front of the eyes of the players, the period of time feels as if it is really in a " real" world, the game is not as simple as the early chess games. Real" world, if you bring some kind of special gloves, you can really "touch" the objects in virtual reality. In addition, the specially designed motion platform allows players to experience high-speed motion jerks, bumps, and tilts.
The main application of computers in movies is movie stunts, where clever computer synthesis and editing can create scenes that could not be filmed in the real world, creating stunning visual effects. The most successful examples are the Star Wars trilogy, Jurassic Park, Forrest Gump, and Pauline Lamp.
There is a trend in the future is that the main characters in the game are switched with each other, and really do the play has me, the game has him, the game and the film and television drama into one.
Computers are also ubiquitous in the field of music. Computers can not only record, edit, save and play music, but also improve the audiovisual effect of music. You can download high-fidelity music from the Internet, or even create digital music directly on the computer, etc.

6. Scientific research
Computers have always played an important role in scientific research. The first computer, ENIAC, was developed for scientific research. Many laboratories now use computers to monitor and collect data from experiments or simulations, and then use software to count and analyze the results for appropriate processing. The computer is an indispensable tool in many scientific endeavors.
7. Family
Computers have entered the family, and the era of family informatization has gradually come to people. From the point of view of the technology so far, all the information products in the family in the future will realize the informationization, the application of computers in the family is mainly embodied in the interactive film and television services, home office, on-line consumption, multimedia interactive education, entertainment and games and intelligent appliances.
In the future, computers will further penetrate into people's lives, become more humanized, adapt to people's lives, and even change the existing way of life of human beings. Digital life may become the main mode of life in the future, people can not leave the computer, the computer will be more colorful.
However, computers also bring us a lot of bad things. Computers can affect our eyesight. If we surf the Internet for a long time and don't let our eyes have a proper rest, it will affect our eyesight and lead to myopia. It will also affect our studies. If we are too addicted to online games and neglect our studies, our academic performance will drop and we may even lose interest in our studies. However, the most serious thing is that it affects the communication between people. Since computers are so convenient, people can just use the Internet to send messages to each other, and even the time for phone calls is reduced; if this goes on, the society will become indifferent and the gap between people will become bigger and bigger. I am convinced that as long as we know how to overcome ourselves, know how to allocate time, make good use of the computer, the computer will be a good helper in our life.
