Mode 1 of computer science and technology graduation thesis: the application of computer science and technology in teaching 1 the application of computer science and technology in teaching
Computer network teaching is very different from classroom teaching, which is influenced by many factors, for example, the teacher's classroom state, the student's classroom state, the limitation of book knowledge and the influence of surrounding environment will all affect the teaching quality. However, computer network teaching is very different. In computer network teaching, students are in the initiative and teachers are mainly in the guiding state, allowing students to learn spontaneously and establishing a mechanism for students' autonomous learning. In this case, it can not only improve students' learning enthusiasm, but also improve teachers' teaching quality. Virtual teaching and distance teaching are two complementary teaching forms, and virtual teaching makes up for the deficiency of distance education. Students can carry out various teaching experiments without leaving home, so as to gain a different learning experience from classroom learning, deepen their understanding of learning content and get a higher promotion. This teaching method can make students' knowledge learning more intuitive and concrete, and make students' learning more intuitive and relaxed. In addition, it can also cultivate students' innovative ability and exploration desire while learning interestingly.
2 the impact of computer science and technology on teaching
The role and influence of computer science and technology in modern teaching is undoubtedly very great. The application of computer technology makes students' learning no longer limited to that little book. Through multimedia courseware and various auxiliary teaching, they have increased a lot of classroom knowledge. While increasing the amount of learning knowledge, it does not consume more time. On the contrary, the effective use of computers greatly reduces the teaching time, so that students can learn more knowledge in the same time. Modern teaching methods have changed the boring teaching form in the past. The rational use of computers can effectively attract students' attention, stimulate their interest and enthusiasm in learning, and make students actively learn and understand knowledge, thus making learning a very interesting thing, changing the previous learning state and forming a positive learning atmosphere. In a big way, the world is like a new era of informationization, digitalization and networking. In this context, computer electronic information technology has been widely developed. Computers have entered thousands of households and become a necessity for people's life and work. Computers have brought great convenience to people's life and study, broken the traditional geographical boundaries and brought people into a new world of knowledge economy. Moreover, computers also play many roles, besides teachers and students, they can also be friends, playmates and tools. People can get many useful things from computers. When the computer is used as an auxiliary tool, it can be used for management. Students can finish their homework on the computer. You can also be a teacher, teaching yourself when you don't understand.

1.2 Computer science and technology are smarter and more professional.
The rapid development and wide application of computer science and technology have promoted the development of integrated circuits, microelectronics and semiconductor transistors, making computer science and technology more intelligent and professional. Computers can be modified and updated according to different personal needs of users. For users with high demand, computers can be specially customized, and users can choose desktop computers, notebook computers, palmtop computers and tablet computers according to different use environments. Computer science and technology can also play its own advantages in other special fields, such as smart home appliances and smart phones. The home-based network distribution system replaces the traditional stand-alone operating system and meets people's daily needs.
1.3 microprocessor and nanotechnology of computer
Microprocessor can improve the performance of computer and reduce the line width and size of transistors in traditional processor chips. Using lithography technology, the exposure light source with shorter wavelength is exposed through the mask, which makes the transistor on the silicon wafer more exquisite and the transistor wire smaller. The rapid development of computer science and technology makes computers faster, smaller and smarter, and traditional electronic components can no longer adapt to the development of computers. Nano-technology is a kind of nano-technology that uses the molecular range and monatomic substances, and can study the application and properties of materials in the range of 0. 1 ~ 100 nm. Using nanotechnology in computer science and technology can reduce the size of the computer and solve the problems of operation speed and integration.
2 the future development of computer science and technology
Nowadays, the application of computer science and technology is more and more extensive, and people's requirements for computer science and technology are getting higher and higher, which urges mathematicians and computer scientists to constantly study computer science and technology, so that computer science and technology can play a greater role in various fields and industries to meet people's different needs. Let's discuss the development prospect of computer science and technology from three aspects: DNA biological computer, optical computer and quantum computer.
2. 1DNA biological computer DNA biological computer replaces the traditional semiconductor silicon chip with a biological protein chip. 1994, American scientist Adlerman first put forward the idea of biological computer. When computer calculates data, biological DNA base sequence is used as information coding carrier, and molecular biology technology and control enzymes are used to change DNA base sequence, thus reflecting information and processing data. This idea increases the computer operation mode, changes the traditional single physical operation nature, and broadens people's understanding of computers. The component density of DNA bio-computer is 654.38+0000 times higher than that of brain neurons, and the transmission speed of information and data is 654.38+00000 times faster than that of human brain thinking. The storage capacity of protein chip of biological computer is 654.38+0 billion times that of traditional computer. In 200 1 year, Israeli scientists developed the world's first DNA bio-computer, which was very small with only a drop of water. In 20 13, scientists from the British Institute of Bioinformatics compiled the music file format and related photos of Shakespeare 154 works by using DNA base sequences, which increased the storage density to 2.2 Pb/g (1024 TB =1Pb) and improved people's understanding of information storage. This major breakthrough made the biological computer.
2.2 Optical Signal and Photonic Computer
Photonic computer is a new type of computer that uses photonic signals to process information, store information, perform logical operations and perform digital operations. Integrated optical path is the basic component of photonic computer, including nuclear mirror, lens and laser. Compared with traditional computers, photonic computers have the following advantages:
(1) Photonic interconnection chip for optical computer has higher integration density. At high density, photons can be unaffected by quantum effect, and the integration density of chips can be improved by the interconnection of photons in free space.
(2) Photons have no mass, are not interfered by media, and can propagate in various media and vacuum.
(3) Light itself has no charge, but is electromagnetic wave, which can cross each other in free space and do not interfere with each other.
(4) Photons travel faster in wires, which is 1000 times that of electrons, and the operation speed of optical computers is faster than that of traditional computers. In the late 1950s, scientists put forward the idea of optical computer, that is, using the speed of light to complete computer operation and storage. Compared with chip computer, photonic computer can improve the running speed of computer. 1896, David? Miller first developed the optical switch, which is very small. 1990, the optical computer work plan of Bell Laboratories was officially opened. According to different components, photonic computers can be divided into all-optical computers and photoelectric hybrid computers. All-optical computer is faster than photoelectric hybrid computer, and can also synthesize recognition gestures, graphics and language. Bell Laboratories has successfully developed a photoelectric hybrid computer, which uses hybrid components. The important task of developing all-optical computer is to develop transistor, which is different from the existing optical? Transistor? No, it can control another lamp with one lamp. Existing optics? Transistor? It is bulky and clumsy to operate, which can not meet the research and development needs of all-optical computers.
2.3 quantum theory computer
Quantum computer uses atoms in quantum state as CPU and memory, and atoms in quantum state can be in different positions at the same time. According to this feature, it can improve the accuracy of computer processing information, improve the operation speed of processing data, and be beneficial to data storage. The basic data unit of quantum computer when processing information is quantum bit, which replaces the traditional? 1? And then what? 0? , strong computing power, the computing speed is 65.438+0 billion times faster than the traditional computer. Scientists in China and the United States have successfully operated on multiple qubits in the laboratory at the same time, which makes it possible to make quantum computers. I believe that with the continuous development of science and technology, with the joint efforts of scientists all over the world, quantum computers will definitely become a reality.
