Today in the twenty-first century, day by day, what are the new things?

In the twenty-first century in China, the television has stepped into thousands of households, but with the development of the economy, the improvement of technology, computers in the twenty-first century has become the new favorite.

The twenty-first century is an information age full of competition, computers make people's learning and information exchange become more colorful, so that the acquisition of knowledge is more convenient.

One time the teacher let me find a historical figure of information, I looked through many books, but still did not find the information required, really anxious. But then I went online and found the information in a short while. This time, I can find the information, really thanks to the computer network ah!

I last saw on TV, there is a village of dozens of farmers to develop resources, planted several acres of green vegetables, but there has been no one to order out. A computer student helped them come up with a way to find customers online. All of a sudden, many customers placed orders online. Within a few days, the piles of vegetables were sold out. The fate of these vegetables, left to rot at home, was changed by a small computer, and it was amazing!

The list of computerized "events" like the one above is endless. It is in the company's business, in people's lives gradually become a very important and indispensable tool. But we must also be clear that the network brings us benefits at the same time, there is also a considerable negative impact.

Some teenagers can not correctly understand the network, the Internet white civilized unhealthy, all-night games, chatting, browsing bad information, addicted to the Internet, and even disregard for the health of the body, uncontrolled access to the Internet. I have heard a message: a boy in the Internet cafe to play games, do not eat, do not drink and do not rest, but to the morning of the third day, because of physical exhaustion and fainted, sent to the hospital to rescue. But it was too late. The cause of death was exhaustion. When I heard this, I thought it was very incredible. A good person, but for a false world and lost his precious life.

Seeing this, many people naturally feel that the network is really bad! But in my opinion, the network can not distinguish between good and bad, the important thing is how you look at and utilize the network. If there is no correct view of the network will be like that teenager, addicted to the Internet and can not extricate themselves; if you can correctly utilize the network, it will not be an invisible sword, but a good assistant.

But in order to make every person correctly recognize the network, I think education, management is the key. Some Internet cafes, game rooms, clearly marked with "minors are not allowed to enter" of the eye-catching words, but there are still a large number of primary and secondary school students in and out to come and go. Such a phenomenon, the relevant departments can be regular spot checks. Schools and parents should also be addicted to the network of young people to carry out education and admonition. There is also some bad information on the Internet to be published to eliminate and stop.

I hope that the future of the people online can see a no bad information, no violence and bloody games, become a real "healthy green network.

The pros and cons of the Internet! The advantages and disadvantages of the Internet! !!! !!! !!! !!! Modern wars rely heavily on communication networks. Sea, land, air three-dimensional defense system, the army's remote dispatch, radar early warning system, the remote launch of missiles, etc. are inseparable from the computer network.

At the same time, in the network to bring us the convenience of time, but also brought a lot of trouble. For example, the network economic crime, illegal invaders, online dissemination of pornographic images, and even some of the moves to jeopardize national security. So we need to talk about the pros and cons of the Internet.

Of course, the dominance of the Internet is favorable to our development, and the benefits of the Internet to everyone are significant, and the name of the information age in the 21st century is also derived from this. So let's take a look at the richness of life that the Internet has brought us.

With the continuous improvement of network bandwidth, people are surfing the Internet faster and faster, and the network can help people do more and more things. People are beginning to give up the traditional and slow letter writing method of contacting each other in favor of e-mail, which transmits information in a timely manner, and the benefits of this are obvious. The benefits are obvious: not only is it faster and less likely to be lost, but it also saves the wood used to make the paper and protects the environment. It can be said that two birds with one stone. This is the reason why a wide variety of websites offer e-mail services. And it also provides a shortcut for businessmen to increase their popularity. It also provides a certain guarantee for the click rate of the website itself, which can be said to be a kind of virtuous circle. Distance education and medical care are also new things brought by the spring breeze of the network. Their prospects for use are very favorable to professionals. You can enjoy the same treatment as going to hospital or school without leaving home. It takes the doctor and the patient or the teacher and the student direct face-to-face communication way, intuitive and fast is its biggest characteristic. With the continuous progress of science and technology, I believe it will soon come into every family, for the benefit of mankind to make contributions.

Not only does the Internet offer many new things, but it is also very helpful in promoting and popularizing the original things. The famous domestic website Banyan Tree is the biggest and most favorable evidence of the network for the promotion of literature. Banyan Tree is a professional literary site with highly qualified editors and decision makers. The most shocking and exciting thing about Banyan Tree is that Banyan Tree is home to a large number of writers who have a strong literary background. There are many writers who enjoy a good reputation in the literary world nowadays, such as Anne Baby, Li Xunhuan and so on. This has attracted the attention and comments of traditional writers. Although there is no unanimous conclusion so far, everyone agrees that it is easier for the young generation to accept literature on the Internet. Therefore, many writers who are literary superstars have put their articles on the Internet for free for everyone to read and circulate, which shows the charm of the Internet. E-commerce is also appearing in front of people as a replacement of traditional business forms, and the development speed is amazingly rapid. Online shopping and the booking of various tickets have long been known and used by the younger generation. Various advertisements on TV also keep reminding people of the arrival of the e-commerce era. It is believed that e-commerce will soon replace its predecessors as a mature business model for people to enjoy. Movies are also supported by the Internet. Although there is still no conclusion on whether online movies are pirated or not, it is undeniable that it has played a considerable role in the promotion of movies, which is no less important than the support of celebrities. We are also happy to see that the internet is starting to play a role in the games that teenagers love. The emergence of various new and interesting online games has enriched everyone's spare time. Some of the competitive games, with the help of websites, have gained a vitality rarely seen in the history of gaming. Starcraft is one of the best examples.

The Web has also provided opportunities for people who are skilled at something but don't have the chance to show it. The most famous, I'm afraid, is *Xuecun, who became famous for his song "All Northeasterners are Living Thunderbolts". "Cuihua, serve sauerkraut!" It also became a fashionable phrase for a while. Another example is *Rascal Rabbit who caught fire with Flash. Its cute image and funny movements made it a big hit among the old-timers, such as Bugs Bunny. And we must know that its appearance is only a few months ago. The latter is the animation industry "old generation revolutionaries". The network's catalytic effect on it can be seen in general.

All in all, the network is a great help to the survival and development of mankind. And the pace of its development and advancement is also unstoppable. We look forward to the network in the future can play a greater role.

But while we are immersed in the joy that the Internet brings us, it also brings us misfortune. With the rapid development of computer technology, the Internet has been transformed from a communication facility serving only the military to a medium for information exchange, leisure and entertainment for human beings all over the world.

It is undeniable that today's fast-developing Internet does bring a lot of speed and convenience to people's lives. But with the increasing development of the network, its shortcomings are gradually revealed.

E-commerce is a with the Internet together with the development of new ways of trading. It can be said that it is the product of the Internet. People can easily conduct transactions online through e-commerce, and cybercriminals will not easily let go of this newborn child of the Internet.

A hacker can easily go from a poor boy to a millionaire overnight. According to a survey published by the Association of British Industries, cybercrime is now rampant in Britain and has seriously affected the development of e-commerce. Jones, chairman of the Association of British Industry, said, "The survey suggests that the development of e-commerce, particularly B2C transactions, is in danger of potentially stagnating as people are cautious about e-commerce due to fears that cybercrime could bring monetary losses and ruin reputations."

Pornography and violence on the Internet is also a major cause of what constitutes cybercrime. Pornography and violence on the Internet are like a kind of spiritual drug that pushes people step by step into the abyss and introduces a road of no return. For example, a fifteen-year-old teenager, addicted to pornographic websites, went so far as to bewitch a girl with ecstasy, and then *defile* and desecrate her according to the actions on the pornographic website. And there are not one or two more instances like this. The cascade of consequences of pornography and violence on the Internet has reached into the policing of society as a whole.

If pornography and violence on the Internet is only for some of the less-willed Internet surfers, the security of the Internet involves every Internet user.

The Internet has a history of development, but its security has not been given much attention. And cybercriminals have seen this and are wreaking a series of unscrupulous havoc on the web.

In August 1999, in the hacker war across the Taiwan Strait, we can see that many official websites suffered damage, except for those official websites with strong security awareness (such as CCTV and the People's Daily online edition).

In January 2000, all networks were hacked, and after repeated battles, the servers were shut down; in February, a network service company in Dalian was hacked, and the computer mail service system collapsed, resulting in serious economic losses; in February, for three days in the 7th, 8th, and 9th, the hackers used a kind of attack method called "denial-of-service" to make the world class Internet. February 7, 8, 9 three days, hackers use a means of attack called "denial of service", so that the world's rated Internet site Yahoo, e-Bay, E-Trade, Amazon, etc. into paralysis, resulting in economic losses of more than 1 billion U.S. dollars; March China's first large-scale online shopping mall chain IT163 was hacked, resulting in the site can not operate, resulting in economic losses of 1.2 billion U.S. dollars... .........

Official and large-scale Web sites have insufficient security awareness, and the situation of personal network security is even more worrying. There was once survey data that said 95 percent of computers in China have network security problems. There have been experts who have warned against cyber terrorism. In the network world there is a more terrible danger: a well-trained "hacker" has the ability to paralyze the entire network world. For example, the Global Internet Domain Name Resolution System (GIDNRS) is housed in the U.S. National Internet Information Center (NIIC), which is in charge of key global Internet data. If a hacker were to cyber-attack it, the global Internet would be paralyzed.

Nearly 60 percent of registered users who landed on Skynet Security Front, the country's largest cybersecurity portal, had computers with cybersecurity vulnerabilities. There are only 1.5 million registered users in Skynet Security Front, which is a fraction of the more than 30 million Internet users in China.
