Middle school students' social investigation report is urgently needed! ! ! The topic is "Advantages and Disadvantages of the Internet ~ ~ ~ Thank you.

In China in the 2 1 century, televisions have entered thousands of households, but with the development of economy and the improvement of technology, computers have become people's new favorites in the 2 1 century.

2 1 century is an information age full of competition. Computers make people's learning and information exchange more colorful and knowledge acquisition more convenient.

Once the teacher asked me to look up the information of a historical figure. I looked through a lot of books, but I still couldn't find the information I wanted. I'm really worried. But then I looked it up online and found the information in a short time. I can find the information this time, thanks to the computer network!

Last time I saw on TV, dozens of farmers in a village developed resources and planted several acres of vegetables, but no one ever ordered them. A computer major helped them figure out a way to find customers online. Suddenly, many customers place orders online. In a few days, this pile of vegetables was sold out. The fate of these rotten vegetables at home was changed by a small computer. How amazing!

Similar to the above computer "deeds" are too numerous to mention. It has gradually become a very important and indispensable tool for companies, enterprises and people's lives. However, we must also be aware that while the network brings us benefits, it also has considerable negative effects.

Some teenagers can't understand the Internet correctly. It is unhealthy to surf the Internet in Bai Wenming. They play games and chat all night, browse bad information, indulge in surfing the Internet, and even surf the Internet regardless of their health. I once heard a news that a boy was playing games in an Internet cafe without eating, drinking or resting. But the next morning, he fainted to the ground because of lack of physical strength and was taken to the hospital for rescue. But it's too late. The cause of death was fatigue. Hearing this, I think this is a very incredible thing. A good man lost his precious life for an imaginary world.

Seeing this, many people naturally think that the network is really bad! But in my opinion, the internet can't tell good from bad. What matters is how you look at and use the internet. If you don't treat the network correctly, you will be addicted to the network like that teenager. If you can use the Internet correctly, it is not an invisible sword, but a good assistant.

But I think education and management are the key to make people understand the network correctly. Some Internet cafes and game rooms are disobedient, clearly marked with the eye-catching words "No minors allowed", but there are still a large number of primary and secondary school students coming in and out. For such a phenomenon, the relevant departments can conduct regular spot checks. Schools and parents should also educate and persuade teenagers who are addicted to the internet. There are also some bad information posted on the internet, which should be put an end to and stopped.

I hope people in the future can see a game without bad information, violence and blood on the Internet and become a real "healthy green grid".

Advantages and disadvantages of the network! ! ! ! ! ! Modern warfare relies heavily on communication networks. The three-dimensional defense system of land, sea and air, the long-distance dispatch of troops, the radar early warning system and the long-distance launch of missiles are all inseparable from the computer network.

At the same time, the network has brought us a lot of trouble while bringing us convenience. For example, network economic crimes, illegal intruders, pornographic pictures on the internet, and even some acts that endanger national security. So it is necessary for us to talk about the advantages and disadvantages of the network.

Of course, the dominance brought by the network is beneficial to our development, and the benefits brought by the network to everyone are remarkable, hence the name of the 2 1 century information age. Then let's take a look at the rich life brought by the Internet.

With the continuous improvement of network bandwidth, people get online faster and faster, and the network can help people do more and more things. People began to give up the traditional and slow way of writing letters and chose e-mail to deliver information in time. The benefits are obvious. Not only is it fast and not easy to lose, but also it saves wood for paper making and protects the environment. You can kill two birds with one stone. This is also the reason why various websites provide mail services. This also provides a shortcut for businesses to improve their popularity. It also provides a certain guarantee for the click rate of the website itself, which can be said to be a virtuous circle. Distance education and medical care are also new things brought by the spring breeze of the network. Their application prospects are very optimistic for professionals. You can enjoy the same treatment as going to a hospital or school without leaving home. It adopts the way of direct face-to-face communication between doctors and patients or teachers and students, which is intuitive and fast. With the continuous progress of science and technology, I believe it will soon enter every family and contribute to the benefit of mankind.

The network not only presents many new things, but also helps to popularize the original things. Banyan Tree, a famous website in China, is the biggest and most favorable evidence that the Internet promotes literature. Banyan Tree is a professional literature website with high-quality editors and decision makers. The most shocking and exciting thing is that a considerable number of writers with rich literary backgrounds are concentrated under the banyan tree. Moreover, many writers enjoy a high reputation in today's literary world, such as Anne Baby and Li Xunhuan. This has also attracted the attention and comments of traditional writers. Although there is no universally agreed conclusion so far, everyone agrees that it is easier for the younger generation to accept literature when it appears on the Internet. Therefore, many leading literary writers put their articles online for everyone to read and upload for free, which shows the charm of the network. E-commerce has also appeared in front of people as a substitute for traditional business forms, and its development speed is surprisingly fast. Online shopping and booking all kinds of air tickets have long been known and used by the younger generation. Various TV advertisements also constantly remind people of the arrival of the era of e-commerce. I believe that in the near future, e-commerce will replace its predecessors and become a mature business model, which is loved by people. Movies are also supported by the Internet. Although whether online movies are pirated is still inconclusive, it is undeniable that it has played a considerable role in promoting movies, no less than stars. We are also glad to see that the Internet has also begun to play a role in the games that teenagers like. The appearance of various novel and interesting online games has enriched everyone's spare time. And some competitive games, with the help of the website, have played a rare vitality in the history of games. The enduring starcraft is the best example.

The internet also provides opportunities for people who have stunts but have no chance to show them. Perhaps the most famous song is * "Northeast People Are Living Lei Feng" and became famous in Xue Cun. "Cui Hua, serve sauerkraut!" It has also become a buzzword for some time. Another example is the rogue rabbit that caught fire with Flash. Lovely image, interesting movements, let it suddenly become a celebrity of bugs bunny and other doyen. And it should be noted that it appeared only a few months ago. The latter is the "revolutionary of the older generation" in the animation industry. The catalytic effect of the network on it is generally visible.

In a word, the network is of great help to the survival and development of mankind. The pace of its development and progress is unstoppable. We expect the network to play a greater role in the future.

However, when we are immersed in the Internet, it brings us joy and misfortune. With the rapid development of computer technology, the Internet has changed from a communication facility serving only the military to a medium for human information exchange, leisure and entertainment all over the world.

Undeniably, the rapid development of the Internet today has indeed brought a lot of convenience and quickness to people's lives. However, with the development of the network, its disadvantages have gradually emerged.

E-commerce is a new trading mode developed with the Internet. It can be said that it is the product of the Internet. People can easily trade online through e-commerce, and cyber criminals will not easily let go of the newborn on this internet.

A hacker can easily go from a poor boy to a millionaire overnight. According to the survey report released by the British Industry Association, cyber crime is rampant in Britain at present, which has seriously affected the development of e-commerce. Jones, chairman of the British Industry Association, said: "The survey shows that people are cautious about e-commerce, especially B2C transactions, because they are worried that cyber crime may bring money losses and destroy their reputation, so the development of e-commerce is in danger of stagnation."

Pornography and violence in the network are also important reasons for cyber crimes. Pornography and violence on the internet, like a kind of mental drug, push people step by step into the abyss and lead them to no return. For example, a boy of 15 years old is addicted to pornographic websites, charms a girl with drugs, and then defiles and desecrates her according to the actions on pornographic websites. And this situation is not one or two. A series of consequences brought by online pornography and violence have penetrated into the public order of the whole society.

If pornography and violence on the internet are only aimed at some internet users who are not determined, then the security of the network is related to every netizen.

Although the Internet has a history of development, its security has not been taken seriously. Because of this, cyber criminals have done a series of unscrupulous damage to the network.

1During the cross-strait hacking war in August, 1999, we can see that many official website were destroyed except for websites with strong security awareness (such as CCTV and People's Daily online edition).

On June 5438+ 10, 2000, all the networks were attacked by hackers. After repeated contests, the server was shut down. In February, a network service company in Dalian was attacked by hackers, and the computer mail service system crashed, causing serious economic losses. In July, August and September of February, hackers used an attack method called "denial of service", which paralyzed the global rating internet sites such as Yahoo, Yi Bei, E-Trade and Amazon. , causing economic losses of more than $654.38+0 billion; In March, IT 163, the first large online shopping mall in China, was suddenly attacked by hackers, which made the website inoperable and caused economic losses of $654.38+0.2 billion. ..........

The safety awareness of official and large websites is insufficient, and the situation of personal network security is even more worrying. According to survey data, 95% of computers in China have network security problems. Some experts have warned against cyber terrorism. There is a more terrible danger in the online world: a well-trained "hacker" has the ability to paralyze the entire online world. For example, the Global Internet Domain Name Resolution System is stored in the National Internet Information Center, which is in charge of the key data of the global Internet. If hackers attack it, the global internet will be paralyzed.

Nearly 60% of registered users who log on to Skynet Security Frontline, the largest network security portal in China, have network security vulnerabilities. Skynet's security front has only 6.5438+0.5 million registered users, which is really rare compared with more than 30 million netizens nationwide.

Young students are always curious about new things. Teenagers' surfing the Internet has always been a concern of education experts and parents. Nowadays, it is a popular and fashionable trend for young students to surf the Internet. Nowadays, young students have occupied a large proportion of netizens. Many young students are even addicted to the internet, and criminals use the characteristics of young students who are not deeply involved in the world to commit crimes. Many female students are abused by criminals for chatting online and meeting strangers. In the United States, a teacher published a disturbing figure: among teenagers, 13% admitted that they had met virtual characters online, but in fact, the number of meetings between these children and unscrupulous porn communicators increased by more than 3000 times over the previous year. More and more sex traders search online lists, newsgroups or school websites to find their targets. Many students with poor self-control indulge in online chatting and engage in "online dating", thus neglecting their studies and ruining their future.

This not only makes parents sad, but also makes educators and social onlookers sad. Therefore, he brought us joy and misfortune at the same time. Anyone who knows a little about philosophy knows that everything has its reason, and it also has two sides in value, that is to say, we can neither be too optimistic nor too negative and pessimistic about the Internet. Sensibility and sobriety are the countermeasures we should take at this time. Teenagers are physically and psychologically immature, with poor ability to distinguish between good and bad things, too strong curiosity and so on. Therefore, the adverse effects of the Internet on teenagers are more significant. Therefore, in order to better resist this kind of infringement, it is also necessary for us to make clear the shadow behind the network.

It is true that most websites and their managers have considerable professional ethics and a sense of mission. However, there are still a few lawless elements who seek huge profits through improper and harmful means. There are more and more pornographic websites, and violent websites are one of the biggest stains on the internet. They charge tourists high fees to enrich their wallets. I don't know how many kind and pure teenagers have been corrupted or even committed crimes by their actions. There are not many examples here. Various newspapers and news have made detailed explanations. We just want to tell our curious or determined friends to give up the idea of "finding out" and let the tragedy never happen again. The network can also play its due role. Of course, the disadvantages of the network will never be just these. For ordinary people, as long as we grasp the problem of a degree, we can avoid the bad influence of the network on ourselves. For those who have mastered strong skills, we hope that they will not show off their talents too much to avoid self-defeating. Because the country has promulgated a series of laws on cyber crime, I think everyone has heard that students in some schools in the United States were summoned by the police for changing information in school files. You should strive for your own achievements, not some extreme measures.

So far, I think we have tried to do some analysis on the internet. How to treat the network? I believe everyone has their own opinions in their hearts. In short, what we have to do now is to make use of the characteristics of the network to serve life and study, stay away from some bad places of the network, and let ourselves grow up healthily.
