Computer Application Field

Information management:
is based on database management system, to assist managers to improve decision-making level, improve operational strategy of computer technology.
Information processing includes data collection, storage, processing, classification, sorting, retrieval and release of a series of work.
Information processing has become the main task of modern computers. is the foundation of modern management.
According to statistics, more than 80% of the computer is mainly used for information management, become the leading direction of computer applications.
Information management has been widely used in office automation, enterprise Computer-aided management and decision-making, retrieval, library,
Film and television animation design, computerized accounting and other industries.
The application of computer has penetrated into all fields of society, and it is changing the traditional way of work, study and life, pushing the scientific calculation of society.
Scientific calculation is the earliest application field of computer, it refers to the use of computer to complete scientific research and engineering technology proposed in the numerical calculation problem.
In the work of modern science and technology, the task of scientific calculation is large and complex.
By using the computer's high operation speed, large storage capacity and continuous operation, it is possible to solve various scientific calculation problems that can not be completed manually.
For example, engineering design, earthquake prediction, weather forecast, rocket launch, etc. all need to be borne by the computer large and complex computational capacity.
Process Control:
Process Control is the use of computer real-time data acquisition, analysis of data, according to the optimal value of the control object quickly automatic adjustment or automatic controls.
The use of computer to process control, not only can greatly improve the level of automation control, but also improve the timeliness and accuracy of control,
So as to improve working conditions, increase yield and pass rate. Computer Process Control has been widely used in machinery, metallurgy, petroleum, chemical industry, electric power and other departments.
Assistive Technologies:
1, computer-aided design (computer aided design, referred to as CAD)
Computer-aided design is a technology that uses computer systems to assist designers in engineering or product design to achieve optimal design results.
CAD technology has been used in aircraft design, ship design, architectural design, mechanical design, integrated circuit design and so on.
The use of computer-aided design can shorten the design time, improve work efficiency, save manpower, material resources and financial resources, and more importantly, improve the design quality.
2, computer-aided manufacturing (Computer aided Manufacturing,cam)
Using computer system to control the process of product processing, the input information is part of the process line and engineering content, the output of information is the tool's motion trajectory.
The integration of CAD and CAM technology enables the automation of design product production, which is becoming a computer integrated manufacturing system.
In some countries, CAD and computer-aided manufacturing, computer-aided testing and computer-aided engineering have been incorporated into an integrated system,
The integration of design, manufacturing, testing and management into a highly automated system has resulted in automated production lines and "unmanned plants".
3, computer-assisted instruction (Computer aided instruction, referred to as CAI)
Computer-aided instruction is the use of computer systems for classroom teaching. Teaching courseware can be made with PowerPoint or Flash.
Not only can relieve the burden of teachers, but also can be lively teaching content, vivid, can be dynamic demonstration of experimental principles or operation process to stimulate students ' interest in learning,
Improve the quality of teaching, in order to train modern high-quality personnel to provide an effective method.
Translation:
In 1947, American mathematician, engineer Woren Wever and British physicist and engineer Andrew Bouth proposed a computer-based translation concept.
Machine translation from the historical stage, and has traversed a tortuous and long road to development. Machine translation was listed as the world's top ten science and technology problem in 21st century.
At the same time, machine translation technology also has a huge application needs.
Machine translation eliminates the gap between different words and languages, and is called high-tech for the benefit of mankind.
But the quality of machine translation's translation has long been a problem, which is still far from the ideal target.
Professor Zhouhaizhong, a Chinese mathematician and linguist, argues that, in the case of human beings who have not yet understood how the brain carries out the vague recognition and logical judgments of language,
It is impossible for machine translation to reach the level of "faithfulness, reach and elegance". This view is probably the bottleneck that restricts the quality of the translation.
Multimedia applications:
With the development of electronic technology, especially communication and computer technology, people have the ability to synthesize various media such as text, audio, video, animation, graphics and image.
constitute a completely new concept-"multimedia" (multimedia).
In the fields of medical, education, business, banking, insurance, administration, military, industry, broadcasting, communication and publishing, the application of multimedia has developed rapidly.
Network:
is made up of a number of independent and information-exchanging computer interconnection systems to realize the sharing of resources.
The use of computers in the network has enabled communication between humans to transcend time and space barriers.
Computer network has become the material basis for the establishment of information society, which brings great convenience and rapidity to our work.
such as the use of bank credit cards nationwide, the use of train and airline ticket systems.
Browse, retrieve, e-mail, read books, play online games, and--internet on the world's largest internet access
Purchase goods, participate in the discussion of many problems, realize telemedicine service and so on.
