Sensor technology, communication technology and computer technology.
sensor technology
Sensing technology, computer technology and communication technology are also called the three pillars of information technology. From the perspective of Internet of Things, sensor technology is an important symbol to measure a country's informatization level. As the second Hangzhou Internet of Things and sensor technology application summit forum, it will promote the rapid development of sensor industrialization in China.
Sensing technology is a multidisciplinary modern science and engineering technology that obtains information from natural resources and processes (converts) and identifies it. It involves the planning and design, development, manufacturing/construction, testing, application, evaluation and improvement of sensors (also known as transducers) and information processing and identification.
communication technology
Communication technology, also known as communication engineering (also known as information engineering, telecommunications engineering, formerly known as long-distance communication engineering and weak current engineering), is an important branch of electronic engineering and one of the basic disciplines. This course focuses on the principle and application of information transmission and signal processing in communication.
Communication engineering studies the transmission of information from a sender (source) to one or more receivers (sink) by electric pulses in the form of electromagnetic waves, sound waves or light waves. Whether the receiver can correctly identify the information depends on the power loss in transmission. Signal processing is an important link in communication engineering, including filtering, coding and decoding.
Specialized courses include computer network foundation, circuit foundation, communication system principle, switching technology, wireless technology, computer communication network, communication electronic circuit, digital electronic technology, optical fiber communication and so on.
computer technology
Computer technology refers to the quantitative calculation and analysis of the system by using the fast and accurate calculation ability, logical judgment ability and artificial simulation ability of the computer, which provides means and tools for solving complex system problems.
With the development of computer technology, it has become an indispensable technical tool for human society. Go to the bank, get a license, go to school for medical treatment, work in government departments, shop in supermarkets, make friends and entertain. It all depends on computers and computer technology. So far, there are more than 400 million Internet users and nearly 800 million mobile phone users in China.
Among them, the number of mobile Internet users reached 277 million, which means that more than half of China people use computer technology every day.
