1 Introduction and development history of computers
1. 1 Computer Introduction
Computer, commonly known as "computer", is an American Hungarian John? Feng? Neumann invented it in 1946. A computer is simply an electronic calculator for high-speed calculation. It can be used for both numerical calculation and logical calculation, and also has the function of storage and memory. Usually, a computer consists of hardware system and software system, and a computer without any software is called bare metal. With the software system, the computer can automatically, quickly and intelligently process massive data according to the program execution.
1.2 computer development history
If we trace the origin of computers, we can proudly start from ancient China. Abacus is an outstanding invention of the ancients and can be said to be the earliest data processing tool. People use the method of fiddling with beads without mental calculation, and the answer can be worked out by a fixed formula. After this concept of "calculation and logical operation" was introduced to the west, it was carried forward by Americans until the birth of the first computer in the middle of the 20th century.
The development of computer has roughly experienced six eras: mainframe stage, small computer stage, microcomputer stage, client/server stage, Internet stage and today's cloud computing era.
Mainframe computers appeared in the 1940s and 1950s. It has experienced the growth process from electron tubes, transistors, integrated circuits to large-scale integrated circuits. During this period, computer technology gradually matured. However, large computers have the disadvantage of high cost. In order to meet the information processing requirements of small and medium-sized enterprises and make the price more acceptable, small computers came into being in the 1960s and 1970s. Small computers are the first time to "shrink" large computers. Its cost is lower than before and its price is more acceptable to shoppers. In the 1970s and 1980s, the appearance of microcomputers was the second "slimming" of mainframes. During this period, Apple and IBM in the United States, especially IBM-PC, which we are most familiar with now, occupied the personal computer market after several years of evolution, making personal computers widely popular.
If you think of every personal computer as a point, the arrival of the client/server phase can be likened to an invisible network that connects all the points together. The client is the foundation of the network, and the server provides the necessary resources for the client. This laid the foundation for the emergence of the next Internet stage.
The internet stage is also called the internet stage. Internet is a wide area network, a local area network and an international computer network composed of a single computer according to a certain communication protocol. Internet, founded in 1969, connects four major computers in the southwestern United States, including UCLA, Stanford University Research Institute, University of California and University of Utah, according to the agreement made by the Research Projects Agency of the US Department of Defense. After that, it went through the stages from text to pictures, voice and video. Nowadays, people's lives are inseparable from the Internet, which has become a necessity in our daily life. The emergence of the Internet is another milestone in the progress of human civilization.
Entering the 2 1 century, computers have become more and more intelligent. Since 2008, the concept of cloud computing has gradually become popular and is regarded as a "revolutionary computing model", which makes it possible for supercomputing power to flow freely through the Internet. It allows users to get rid of the complexity of technology and deployment and get applications. Cloud computing, including development, architecture, load balancing and business model, is the future of software industry.
Two aspects of the influence of computer development on human beings
The development speed of modern computer is amazing, and the computer industry has experienced a development process from hardware-centered to software-centered, and then to network application-centered. The development of modern society relies on computers to an unprecedented height. As the dominant factor in the modern advanced science and technology system, social informatization triggered by computers is rapidly changing the social outlook, economic growth mode and people's life and thinking mode, and has a great impact on all aspects of social production and life.
In daily life, computers have expanded from the simplest data calculation and processing to enterprise management, production and sales, financial accounting, industrial control and technical data processing, saving a lot of manpower and financial resources. In addition, multiple computers can be combined into a regional network system, and one host can control the extensions to form an effective connection network, which greatly improves the daily work efficiency.
At the same time, with the advent of the Internet era, the network has also injected new vitality and vitality into social life, announcing the arrival of a new technological revolution. The main element of the computer and Internet era is information. Through computers and the Internet, the development of information technology has been accelerated unprecedentedly. This powerful way of communication enables people to understand and transmit information through more channels and faster, and the timeliness and effectiveness of information become stronger. People can cross the barriers of time and space, get a lot of information at a very fast speed, broaden their horizons and understand the world. Transactions can be reached online without leaving home, and supply and demand information can be fully exchanged. In addition, it has promoted the progress of information-related industries, such as biotechnology and electronic technology. The development and utilization of some new materials and energy sources have also made great progress in this process. Computers and networks have penetrated into our personal life and social structure forever.
In today's highly developed information industry, computer technology and network have become the necessities of human life. However, the development of everything has two sides, which not only brings various benefits to mankind, but also brings many disadvantages. First of all, computer technology has not yet developed to a very perfect stage, and electronic data still has instability and interference. The most direct cause of this trait is computer virus. It has become a major factor endangering social security. Thirdly, the current network supervision is not strict enough, and the communication characteristics of the network cause information flooding. All kinds of information rubbish will weaken the thoughts of some netizens with low moral awareness and cause great social harm. Third, compared with the rapid development of the Internet, many laws, regulations and other policies are still not perfect, and the control technology is still relatively backward, which leads to many problems such as intellectual property plagiarism and online fraud. These are the negative products of the rapid development of information technology.
In addition, from a personal point of view, the development of computers and networks makes people spend more and more time facing computers. It has been reported that if people face computers for a long time, it is very easy to cause physical injuries such as cervical spondylosis and visual impairment. In addition, with the improvement of network technology, the abundance of mobile phones and tablets, the popularity of chat software and online games, there is no obstacle between time and space, and the direct communication between people is getting less and less, which leads to the weakening of people's collective consciousness and the gradual decline of people's social consciousness.
Facing the development of computer and network, what should we do?
With the rapid development of computer technology and network today, computers and networks are entering every corner of human society at an alarming rate. It brings people inestimable wealth opportunities and unpredictable potential crises. So in the future, what kind of attitude and way should we use to face the positive and negative changes brought by this "double-edged sword"? I think we should have a deep understanding and a clear understanding of this.
First of all, from the perspective of * * *, improve various laws and regulations and strengthen the protection of intellectual property rights and copyrights; Fully understand and take necessary measures to support the development of computer industry, cultivate sophisticated computer talents, comprehensively improve the level of computer technology and network security supervision in China, and make computer viruses, bad websites and network fraud everywhere.
Secondly, from a personal point of view, we should correctly understand the power of computers and networks, face the new life and environment at a higher level, constantly change our thinking and behavior, not be fettered by redundant information, "take its essence and discard its dross" and absorb the positive energy transmitted by the network; Increase your knowledge reserve, master higher computer technology, be able to handle some computer and network problems calmly, and use these knowledge and skills to study, work and live better.
Science is developing, human beings are making progress, and all new things in history have to go through a tortuous development process. With the continuous efforts of generation after generation, the future computer will certainly serve mankind faster, better and more harmoniously.
