On the influence of computer on life The first paper "Talking about computer network and its influence on life"
Abstract: With the application of computers in various fields of society, computers are playing an increasingly important role in all aspects of people's work, study and life. Therefore, it is imperative to realize the fragility of the network and the seriousness of the potential threat, and adopt a strong security strategy to make the computer network truly enter our lives safely and play its greatest role.

1 the concept of computer network security
Will the International Organization for Standardization? Computer security? Defined as:? Technical and governance security protection of data processing system, and protection of computer hardware and software data from unexpected and malicious reasons? . The meaning of network security is the extension of information security, that is, network security is the protection of confidentiality, integrity and availability of network information. Network security has both technical problems and governance problems, which complement each other and are indispensable.
2 computer network security risks
(1) * * enjoyment of network resources. What is the most important function of computer network? Enjoy resources * * *? . But it also provides an opportunity for attackers of system security to use the resources enjoyed by * * * to destroy.
(2) Vulnerabilities in the network operating system. Operating system vulnerabilities refer to the problems or technical defects existing in the computer operating system itself. Due to the complexity of network protocol implementation, it is determined that there must be various defects and loopholes in the operating system.
(3) Defects in network system design. Network design refers to the design of topological structure and the selection of various network devices. Network equipment, network protocol, network operating system, etc. Will directly bring security risks.
(4) the openness of the network. The concrete manifestations are as follows: ① Making a lot of useless data, which causes network congestion to the attacked host and makes it impossible for the attacked host to communicate with the outside world normally. (2) Taking advantage of the defect that the attacked host provides services or handles repeated connections in the transmission protocol, the attacked host repeatedly sends out aggressive repeated service requests at high frequency, which makes it impossible for the attacked host to handle other normal requests in time. (3) Taking advantage of the defects of the service program or transmission protocol provided by the attacked host, repeatedly sending abnormal attack data causes system errors, allocates a lot of system resources, and makes the host in a suspended state or even crashes.
3 changes brought by computers to people's social life
Through the Internet, people can find what they need from the vast amount of information, exchange messages with relatives and friends far away from the other side of the ocean, exchange feelings with strangers they have never met, enjoy the teacher resources and knowledge resources of ideal schools at home, libraries, offices and other places, sit at home and receive consultations from medical experts from all over the world, and realize home online shopping and home online marketing. These are unimaginable in the past.
3. 1 education modernization
Due to the continuous development and wide application of computers, multimedia teaching is becoming more and more popular; Nowadays, the application of computer in education has developed unprecedentedly, and it has been widely used in different levels and fields of education. Such as computer-aided teaching, computer management teaching, distance education and so on.
Distance education is one of the most active and promising new educational models, in which computers stand out in the transformation of traditional educational models. Its main characteristics are as follows: students and teachers are geographically separated, not face to face; Using modern communication technology to provide two-way interactive function; Students can attend classes anytime and anywhere, regardless of time, place and space. It breaks the traditional face-to-face classroom teaching mode, and students can enjoy the teacher resources and knowledge resources of the ideal school at home, library, office and other places. Students can get a good school education when they are not in class.
3.2 Convenience of production and life
The application of network in people's daily life has naturally changed people's way of life. Through the computer network, people can finish their work and study tasks without leaving home, save more time to deal with other things, and liberate people in action and even in thought. No matter when and where, people can always enjoy the speed brought by the internet, so that people in different corners of the earth can receive the same news in the shortest time. This new way of information dissemination can not only span time and space, but also make the publishers and receivers of information interact closely and serve mankind in a faster way of information exchange.
The internet has changed the way of human production. In enterprise production, people can not only design the appearance, packaging and performance of products completely through computers, but also control the whole process of product production, packaging and distribution through computers, saving a lot of manpower and financial resources.
3.3 the negative impact of computer networks
Everything has two sides. Although computer network can bring a lot of benefits to the development of our society, it will also bring a lot of harm to the development of our society if we don't make proper use of it. Although the development of computer network technology has played an indelible role in promoting the development of human society, the role and reaction often coexist, and the problems brought about by technological development are also obvious. Facing the virtual network world, more and more people are exposed to the network, and there are more and more problems on the network, such as many people using the network to commit crimes; Many people are addicted to the internet and divorced from real life, which leads to a crisis in real life. Similarly, taking teenagers as an example, as more and more teenagers gradually contact and go deep into cyberspace, the negative impact is increasingly prominent. Therefore, the future of the network should develop towards the scattered and tense interactive form of individual and society, individual and group, individual and sex, so as to realize the dual goals of individual free development and social healthy development.
4 conclusion
There is no denying that the computer network has brought us various conveniences. The application in various fields not only greatly improves the production efficiency, but also greatly promotes the civilization and progress of society. We must correctly understand the problem of network security, fully consider the factors of network security, make the network truly serve the social development, and truly and safely apply the network to our lives.
