Computer technology and the progress of human society
This paper describes the history of computer technology, its future development direction and its influence on human society!
Keywords: social impact of computer technology development
In the development history of modern society, computer technology has always played an important role. Great changes have taken place in our world since the birth of computers. Computers have made our "earth" smaller and smaller, and now it is simply a "global village". Turn on the computer and click the mouse to "roam" our "global village" at will.
The development direction of computer technology
1946 The world's first computer came out. According to computer performance and software and hardware technology, computer development is divided into the following stages:
① The first stage: Electron tube computer (1946-1957) is characterized by:
(1) Making basic logic elements with electron tubes.
(2) Use an electron ray tube as a storage component.
(3) Input and output equipment is backward, and punched cards are mainly used.
(4) There is no system software.
② The second stage: transistor computer (1958-1964) has the following main features:
(1) Making basic logic elements with transistors.
(2) The magnetic core is generally used as the main memory, and the disk/drum is used as the external memory.
(3) System software (monitoring program) began to appear, the concept of operating system was put forward, and high-level language appeared.
③ The third stage: the integrated circuit computer (1965-1969) has the following main features:
(1) Making various logic elements with small and medium-sized continuous circuits.
(2) Use a semiconductor memory as the main memory.
(3) The system software has developed greatly.
(4) The programming method is structured programming.
(4) The fourth stage: large-scale, ultra-large-scale integrated circuit computer, its main features:
(1) The basic logic elements are VLSI and VLSI.
(2) As the main memory, the semiconductor memory has higher integration and larger capacity; External memory not only widely uses soft and hard disks, but also introduces optical disks.
(3) Various convenient input and output devices have appeared one after another, such as large-capacity disks, optical disks, mice, image scanners, digital cameras, high-resolution color displays and laser printers.
(4) The software industry is highly developed, and all kinds of practical software emerge one after another.
(5) Computer technology is combined with communication technology, and computer networks (WAN, LAN, LAN) closely link the world.
(6) With the emergence of multimedia, computers have integrated image, graphics, sound and word processing, which has set off a revolution in the field of information processing, and the corresponding information superhighway is being planned and implemented.
The future development direction of computer
The future computer will be based on VLSI, and will develop in the direction of giant, miniaturization, networking and intelligence.
1. Huge
Giant refers to a computer with higher computing speed, larger storage capacity and stronger functions. The supercomputer being developed at present can operate at a speed of billions of times per second.
2. Miniaturization
Microcomputer has entered small instruments and equipment such as instruments and household appliances. At the same time, it is also the heart of industrial control process, which makes instruments and equipment "intelligent". With the further development of microelectronics technology, microcomputers such as notebook computers and palmtop computers will be welcomed by people with better cost performance.
3. Establish a working network
With the deepening of computer application, especially the increasing popularity of home computers, on the one hand, it is hoped that many users can enjoy information resources, on the other hand, it is also hoped that computers can transmit information to each other for communication.
Computer network is the product of the combination of modern communication technology and computer technology. Computer network plays an increasingly important role in the management of modern enterprises such as banking system, commercial system and transportation system.
Become smart
The research of computer artificial intelligence is based on modern science. Intelligentization is an important direction of computer development. The new generation of computers will be able to simulate the mechanism of people's sensory behavior and thinking process, and carry out "seeing", "listening", "speaking", "thinking" and "doing", and have the ability of logical reasoning, learning and proof.
The application field of computer and its influence on human beings.
The application fields of computers mainly include:
1. Scientific calculation (or numerical calculation)
2. Process detection and control
3. Information management (data processing)
4. Computer-aided system
5. Network application
The influence of computer application on human society
1. Scientific calculation (or numerical calculation)
Early computers were mainly used for scientific calculation. At present, scientific computing is still an important field of computer application. Such as high-energy physics, engineering design, earthquake prediction, weather prediction, aerospace technology, etc. Due to the high speed, high precision and logical judgment ability of computers, new disciplines such as computational mechanics, computational physics, computational chemistry and biological cybernetics have emerged. 2. Process detection and control.
Computer detection system is called computer detection system, which uses computer to automatically detect some signals in industrial production process, stores the detected data in the computer, and then processes the data as needed. Especially, the intelligent instrument formed by the introduction of computer technology has pushed industrial automation to a new height.
3. Information management (data processing)
Information management is the most widely used field of computer at present. Use computers to process, manage and operate any form of data, such as enterprise management, material management, report statistics, account calculation, information retrieval, etc. In recent years, many domestic institutions have established their own management information systems (MIS). Manufacturing resource planning software (MRP) has also been adopted by manufacturing enterprises, and electronic information exchange system (EDI) has been gradually applied to commercial circulation, that is, paperless trade.
4. Computer-aided system
1) computer aided design (CAD) refers to the use of computers to help designers carry out engineering design, thus improving the automation of design work and saving manpower and material resources. At present, this technology has been widely used in the design of circuits, machinery, civil buildings, clothing and so on.
2) Computer Aided Manufacturing (CAM) refers to the use of computers to manage, control and operate production equipment, thereby improving product quality and reducing production costs. Shorten the production cycle and greatly improve the working conditions of manufacturing personnel.
3) Computer-aided testing (CAT) refers to the use of computers for complex and large-scale testing.
4) Computer-aided instruction (CAI) refers to an automatic system that uses computers to assist teachers in teaching and help students learn, so that students can easily learn what they need.
5. Network application
The application of computer in network is an epoch-making application. The development of computer network has brought great changes to human society and shaped a social civilization form different from agricultural society and industrial society-network social civilization form. The network has a great influence on people's daily life, social economy and politics.
Today's society has entered the network society, and the computer network has penetrated into all aspects of people's lives, affecting people's daily lives and changing the pace of people's lives. From the previous post office letters to the current online mail, from the previous face-to-face conversation to the current QQ, from the previous physical store shopping to the current online shopping, from online shopping to online stock trading, from online games to online classes, all can be completed in front of the computer. With the popularity of network communication, some emerging network languages are entering people's lives.
Although the network has brought us many benefits and conveniences, it also has many shortcomings. Some students are addicted to surfing the internet, and computers are not used in the right way, which leads to a sharp decline in their studies. Some students actually play truant or secretly take home money to play in order to go to Internet cafes. Playing computer for a long time is bad for your eyesight. There are many typical examples in our class.
I hope those students who are addicted to the internet will wake up quickly and let themselves use the computer correctly.
The era we live in is the era of great science, and technology is advancing by leaps and bounds. With the rapid development of IT technology, computer technology has increasingly penetrated into all fields of social life. It can be said that our world is a world of computers, and computers have become "strategists" of the times. Undoubtedly, the application of computers in various fields not only greatly improves the production efficiency and brings convenience to people, but also greatly promotes the civilization and progress of society. However, any science and technology is a "double-edged sword", which brings civilization to human beings and also has some negative effects, and computer technology is no exception. Through the influence of computer on people's study, life and work, people have formed a new interpersonal relationship, so people often deviate from their spiritual values involuntarily, which leads to misleading. Therefore, it is necessary to standardize the development of computers.
Vigorously develop computer technology and constantly promote the development of human society.
We will continue to vigorously develop computer technology, making computers cheaper, smaller, faster, more storage, more developed networks, and so on. We will continue to work towards this goal.
Science and technology are the primary productive forces. The degree of human social civilization is closely related to the development of science and technology. The development of computer not only promotes the modernization of science and technology, but also greatly promotes the improvement of human social civilization.
Based on the characteristics and advantages of computer, such as high speed, memory characteristics and logical judgment, large storage capacity, high precision, high reliability, strong versatility and resource enjoyment, it has been widely used in science and technology, national economy, social life and other aspects, bringing great wealth and convenience to modern human society and greatly promoting modern human civilization.
