Computer technology is one of the fastest-growing science and technology in the world, and its products are constantly being upgraded. At present, computers are developing in the direction of mega, miniaturization, intelligence, and networking. The performance of computers is becoming more and more advantageous, and the scope of application is becoming more and more extensive, making computers necessary for work, study, and life. Tool of.
1 The development of computer technology mainly has the following four characteristics.
Nowadays, personal computers have swept the world, but due to the deepening of computer applications, the demand for supercomputers and mainframes has steadily increased. Giant, large, small and minicomputers have their own application fields, forming a multi-polarization. The situation. For example, supercomputers are mainly used in cutting-edge science and technology fields and defense industry fields such as astronomy, meteorology, geology, nuclear reaction, space shuttle and satellite orbit calculation, which mark the development level of national computer technology. At present, supercomputers with operating speeds of tens of billions to trillions per second have been put into operation, and more high-speed supercomputers are being developed.
Intelligentization enables computers to have the ability to simulate human perception and thinking processes, making computers a smart computer. This is also the goal that a new generation of computers is currently being developed. Intelligent research includes pattern recognition, image recognition, natural language generation and understanding, game, automatic proof of the theorem, automatic programming, expert systems, learning systems, and intelligent robots. At present, a variety of robots with partial human intelligence have been developed.
Networking is another important trend in the development of computers. From stand-alone to networking is the inevitable result of the development of computer applications. The so-called computer network nation refers to the interconnection of computers distributed in different places by modern communication technology and computer technology to form a network structure with a large scale, strong functions, and communication with each other. The purpose of networking is to enable resources such as software, hardware, and data in the network to be shared by users on the network. At present, the communication network is as large as the world, and the LAN inside the laboratory is very popular. The Internet has connected more than 150 countries and regions including China. Since the computer network realizes the sharing and processing of various resources and improves the efficiency of resource utilization, it has been well received by users and has been widely used.
Multimedia computers are one of the most compelling high-tech in the current computer field. A multimedia computer is a computer that uses computer technology, communication technology, and mass communication technology to comprehensively process multiple media information. This information includes text, video images, graphics, sounds, text, and more. Multimedia technology creates an organic connection between multiple information and integrates it into a system with human-computer interaction. Multimedia computers will truly improve the human-machine interface, allowing computers to evolve in the most natural way humans receive and process information.
2, The Future Of Computers
1, quantum computer
Quantum computer is a kind of quantum physics equipment that follows the laws of quantum mechanics for high-speed mathematics and logic operations, storage and processing. When a device is assembled by two sub-components, processing, and computing quantum information, when running quantum algorithms, It is a quantum computer.
2, Neural Network Computer
The overall brain speed is equivalent to 1000 trillion computer functions per minute, and the biological brain neural network can be regarded as massively parallel processing, tightly coupled, self-reconfigurable computing network. The computer design model is extracted from the brain working model, and the neural mechanism of the human brain is imitated by many processors, the information is stored in the communication between the neurons, and a large number of parallel distributed networks are used to form the neural network computer.
