2022 Network Security Knowledge Cloud Classroom Review 1
In this era of rapid development of information technology, if you say that you don't know what the network is, you will definitely encounter a sigh, and no one will believe you. The internet is amazing. It connects the world. In the past, people in Wan Li thousands of miles away could only communicate by writing letters or sending telegrams. Now through the Internet, people can chat videos at any time, and with a click of the mouse, the other party will receive your holiday wishes ... The Internet has made the ancient "God never shuts one door but he opens another" a reality!
However, everything has two sides, a kitchen knife can cut vegetables and hurt people, and an electric tiger can illuminate and electrocute people ... Although the network has brought us a lot of convenience, it has made countless teenagers addicted to it, trapped in the quagmire of video games, and their academic performance has naturally plummeted! According to Teacher Jiang, my big brother who was admitted to the successful middle school with the first place failed three books because of this!
Some net worms soak in chat rooms all day, their eyesight drops greatly, and even cause retinal detachment; What's more, influenced by bad information, they actually embarked on the road of illegal crimes, and even had a vicious incident of self-harm or murder.
You may have heard of such a thing: a boy of 17 years old in Beijing hacked to death his grandmother on the spot in order to steal money to go to an internet cafe, and his grandfather was seriously injured! What a terrible tragedy! If not addicted to online games, how could there be a kind grandmother missing in the world? How can there be an outstanding student missing from the school? How can there be another juvenile murderer in the detention center?
Network, while you bring convenience to people, you also push countless teenagers who have lost their way to the abyss of sin and darkness!
Network is a double-edged sword. As long as we surf the Internet healthily and reasonably and regard the Internet as a tool for study and life, it will bring us convenience. However, if we just regard the Internet as a toy and immerse ourselves in it, it will immediately become a ferocious magic net, which will entangle your hands and feet, tightly bind your mind and stifle your youth!
Dear students, we must grasp ourselves! Although we are still primary school students, we should lay this vaccination in time for our future and accept the teacher's inculcation-"be enlightened on the Internet". In the future, we should make good use of the network and let it serve our study and life honestly!
Review of 2022 Network Security Knowledge Cloud Classroom II
With the migration of people's times and the development of science and technology, the network has also entered people's families and become an indispensable tool for people to exchange information and consult materials. The network has opened a brand-new and colorful world for people.
When you watch cute cartoons, play fascinating computer games, get on the express train and answer overseas calls, … do you feel the power of science? Science has not only changed the world, but also changed our lives. Science is all around us. Like our primary school students now, with good economic conditions at home, it is not a problem to buy a computer. We can use the computer to search some necessary study materials from the internet, and we can search them in a very short time, which saves time and effort. Unlike before, I have to go to the library to look for books everywhere, and sometimes I can't find them at all.
With the internet, in your spare time, listen to music online and relax; With the network, you can learn knowledge and broaden your horizons; With the network, you can know the state affairs in the first time; With the internet, we can enjoy browsing the web, enjoying beautiful articles, enjoying the wonderful and feeling the beauty of life. ...
To be sure, the role of the network is the most widely used, which enables students to obtain more information and knowledge. But behind so many benefits, there are many terrible hidden dangers. The internet is sometimes like a talon, which leads you step by step to the road of crime. Nowadays, it is often seen in news and newspapers that many primary and middle school students are addicted to online games, which makes students fascinated and inattentive in class, leading to a decline in academic performance and delay in learning. Even in order to surf the Internet, I stayed up all night in Internet cafes and stole, cheated and robbed when I had no money, which seriously disrupted social order.
Network can bring us many benefits, but also many disadvantages. We should clearly realize the duality of the network. What a civilized and beautiful world this society should be as long as we arrange our study and surfing time reasonably and make computers truly become our teachers and friends in life!
Review of 2022 Network Security Knowledge Cloud Classroom 3
2 1 century is the information age, and the birth of the internet has brought convenience to people all over the world. In life, we students often look for information. But in the vast sea of books, there are times when you can't find information, and it takes a lot of time to look up books. But if you click the mouse in front of the computer, the information you need will appear immediately, quickly and conveniently.
Through the network, we can establish contact with the world, obtain external information, understand the world more comprehensively and face the information society directly. Internet can also improve our own abilities in various aspects, for example, it can improve typing speed and enhance our understanding ability, so surfing the Internet is a good thing.
However, surfing the Internet also has disadvantages. Surfing the Internet is very addictive. Once addicted, it's like being possessed. Once someone is hooked, they will spend all day in the Internet cafes and lose interest in other things, which will naturally affect their study. Surfing the internet is too frustrating and consumes energy. Students will be in a trance and their final grades will plummet.
Let me give you a few typical examples: for example, there are several "net bugs" in our class who specialize in playing games online. Whenever I sweep the floor, I often hear Lin Zhilin and Zheng Han talking about something wonderful: "How many people did you kill with a knife? How can you fight a gun battle? " You can't play while playing. "and so on. There are two others, you Cheng Xiao and Chen Hao. You Cheng Xiao stayed in class, said nothing in class, and didn't mind reading. I always felt that there must be something wrong, so I came up with a plan of "the hole looks like a fire". After investigation, it was found that you Chengxiao dreamed of the "wonderful" pictures in the game during class, so that he was unwilling to attend the class.
On the Internet, there are some uncivilized websites and many unhealthy contents. These unhealthy contents invaded students' hearts, which made students with low resistance gradually escape from reality and alienated their personality, and finally ruined their bright future because of playing with things. In the internet cafe, a male classmate lost badly in playing games and had no money to go to the internet cafe, so he stabbed his grandmother who loved him the most with a knife. Teenagers who could have a bright future have ruined their bright future.
One day, I came across a sentence: "Internet" is a free and equal world, but there is no government, no police and no army. A "paradise" without hierarchy, wealth and discrimination. "But I don't think the' network' world is a real' Xanadu' or a pure land. This is just a virtual world. Entering the "network" is like entering the global village. There are all kinds of colorful information. It is an ocean of information, but it can also be called an information "garbage" field. Students, especially, are easily misled by the Internet.
Therefore, surfing the Internet is a serious matter, please think twice before you do it!

Now is an information age, and the network has become an indispensable thing.
The internet has many advantages, such as: you can find what you want; You can shop online; Can teach online; You can make online videos to connect you with friends and relatives thousands of miles away; You can also browse other students' wonderful blog posts and make friends through the school newsletter network established by the school.
I often go online to pay attention to the school newspaper, read the blog posts of my classmates and friends. We left messages to each other, from which I learned many different things and made many friends, which brought infinite fun to my life and study.
Father works in other places and doesn't often go home. Now with online video, we can often talk face to face online, which can not only solve my father's thoughts, but also save money. Network teaching has been implemented in schools. As long as our teacher clicks on the knowledge we want on the computer, it will immediately appear on the TV screen connected to it. Sometimes, I encounter some problems. As long as we look it up online, we can reveal the answer to the question. Why are you doing this? When our school held a poetry festival, it was transmitted from the lecture hall to our classroom through the internet. Online shopping is also very common now. This Valentine's Day, Dad didn't come back. He ordered a handbag for his mother online and arrived in the morning of February 14. Online shopping can save energy, time and convenience. You have everything you want. Although the internet is good, it also has disadvantages. For example, some children can't help playing games online often, which not only delays their study, but also reduces their eyesight. There are some unhealthy information on the internet that leads people to commit crimes.
We are still young, so we must grasp the degree of surfing the Internet and don't hurt ourselves. Green surfing the internet is to let us master more knowledge and be a useful person to society.

Network, a familiar and unfamiliar new term, did not know when it broke into our life. But there is no doubt that this little-known novelty has become the highlight of our daily life. If you, a teenager of 2 1 century, know nothing about the internet, it can only show that you are out of touch with the world and can't keep up with the fast pace of the times.
Indeed, the emergence of the network undoubtedly takes up people's extra time, facilitates people's daily needs, broadens people's horizons and enriches people's spare time after work. The advantages of the network are numerous, which can be seen from the above points. However, everything has two sides: good and bad. This double-edged sword makes us have to be vigilant. We might as well consider the network from another angle. It is not difficult to ask questions: what is the security of the network? Network, what is its moral bottom line? The question mark in front of us is weighty enough for people to ponder: online games have caused many teenagers' academic performance to plummet, their reputations have been discredited in Sun Shan, and they have even embarked on the road of crime. Chatting online makes many people homeless and unemployed at home. At the same time, online cheating is even more inhuman. In order to make huge profits, some lawless elements will sacrifice everything of others to satisfy their personal interests. As a result, neither side has a happy ending. All the above are the facts that happen around us, and the prospect of the network can be imagined, which is not optimistic. There is no safe and moral behavior in the network, how can people talk about honesty and trustworthiness, even in the virtual world network, it is also against morality and ethics.
Therefore, there is a saying in the ancients: "If you have it, you will change it, and if you don't, you will be encouraged." We are not afraid of mistakes in this famous classic sentence, as long as we correct it.
In the eyes of thinkers, the network itself is various, including truth and falsehood, good and bad, gold and feces. The network is a big space, and people's postures in it are also varied. The person who makes the network is a saint, the person who refuses the network is an idiot, the person who listens to the network is a pariah, and the person who destroys the network is not a good person. Scholars who know the internet but despise it are mediocrities, those who keep it are fools, and those who use it are wise.
In the eyes of the judge: everyone should have a balance in his heart and never change from left to right to measure the dribs and drabs in his heart.
In my heart: In fact, I know best what I think, do and know. As for what you should do next, it depends on whether the enlightenment lamp in your heart can illuminate your inner moral bottom line.

With the development of information technology and the increasing popularity of computers, the network has long been an indispensable part of life. It not only gives full play to the multiple functions of the network, but also closely combines technology with life, providing people with a more comfortable and convenient information living environment. As long as you click the mouse at home and connect to the Internet, you can "know what's going on in the world without going out", and even your daily needs such as food, clothing, housing, transportation and entertainment can be solved at one finger.
I like surfing the Internet often, but I am always careful. Because although the network world is varied and all-encompassing, there are many novel things, but there are also many hidden traps. Just like Trojan horse virus, it will not only slow down the running speed of computers, but also reveal personal data, and important data may also be stolen. There are also some bad websites, which will do great harm to the body and mind if they are browsed by underage children; There are also some online dating and online games. If you are not careful, you may be cheated by netizens you have never met, or even have both money and people! Such examples abound, and the victims are not only children, but even adults.
As the saying goes, "water can carry a boat, but it can also overturn it", and the same is true of the Internet for us, depending on how users grasp it. If used well, it will be a good helper in work and life; If you don't make good use of it, you may hurt yourself and leave regrets. In order to keep bad websites away from us, avoid physical and mental harm, and refuse viruses to invade personal computers, we should pay attention to "don't download unknown or illegal software, don't open unknown links, don't disclose personal data, and don't go out with netizens" when surfing the Internet, to protect personal safety and enjoy the online world.
I hope everyone can enrich their network knowledge and literacy in peacetime, let themselves soar fearlessly in the network world, and learn fearlessly in the rich resources brought by the convenience of the network.

In today's society, the network has spread to thousands of households, bringing people a lot of convenience. However, the Internet is also a double-edged sword. While bringing convenience to many people, it also hurts a considerable number of people, especially our teenagers.
The network has opened many windows to the unknown world for us, and people can gain rich cultural knowledge through online learning; You can get to know all kinds of strange things around the world and increase your scientific knowledge by surfing the Internet. More importantly, people can still do business online now. One of my classmates is a qualified netizen. He used to study very well and his family conditions were superior. He used computers rationally by virtue of his own advantages, never logged into bad websites, never indulged in virtual worlds, only looked up what he should look up to enrich his brain, and learned a lot of scientific and cultural knowledge that our peers could not learn. At that time, we all thought he was a "small computer". The Internet has brought us many benefits.
Of course, unqualified netizens account for the majority of teenagers. Taking our school as an example, it is a cliche to govern students' surfing the Internet. Rather than surfing the Internet, they are escaping from reality. The current online virtual world is enough for people to indulge in it. Why does the school keep saying that it is forbidden to surf the internet, but it can't break its roots? It is because the online virtual world is so attractive that most people can't extricate themselves. The virtual world in the computer is in sharp contrast with reality. Inside, they can become sworn brothers, advance and retreat together, advance and retreat together, and do whatever they want. This is exactly what they want, and that may be their real spiritual home. All this is due to the internet. Without the internet, how can they indulge in it? Internet has led many teenagers astray, neglected their studies and bright future, and brought us a lot of harm.
Although the Internet is a double-edged sword, I think which blade to use depends on people themselves. Otherwise, how can there be qualified netizens and unqualified netizens? Therefore, people should strengthen self-discipline and make rational use of computer networks, and naturally a double-edged sword will become a double-edged sword.

The magical computer world is varied, convenient and fast, which brings infinite convenience to people.
The invention of computer information technology is very rapid, such as e-mail, instant messaging, computer software download and so on. You don't even have to go out. As long as you sit in front of the computer, everything is very simple. You can auction what you want to sell through the Internet, and you can also make friends and chat around the world through the Internet! So the computer network world is really a convenient invention, which can be said to be far away and close at hand!
Computers do have many advantages, but they also have many disadvantages. You must use computer antivirus software to resist viruses, so that your basic information and many important information will not be leaked because of the invasion of viruses and hackers, and will not be used to do things that violate the law. That's out of control!
The convenience of computers sometimes becomes a channel for people to commit crimes. Drug trafficking, kidnapping, fraud and other incidents emerge in an endless stream. However, if you don't choose letters and documents from unknown sources at will, log in to your personal data, be careful when making friends online, and don't go to some strange and inexplicable websites, then many things can be prevented before they happen.
The invention of information technology computer has brought unprecedented changes and convenience to people's lives, enabling us to communicate with everyone in every corner of the world. It is appropriate to describe it as "God never shuts one door but he opens another". In the online world, we can't give up eating because of choking. As long as we are careful not to jump into the trap designed by the bad guys, we can roam happily and freely.

Nowadays, the network has entered thousands of households and become a hot topic of discussion. Network not only provides a platform for people to exchange information, but also helps people to work and study.
Once, the geography teacher asked us to write the transit phenomenon and collision phenomenon in our exercise books. However, as far as I remember, the teacher did not teach these two phenomena. What should I do? Just when I was confused, my mother came to my room. I told my mother the whole story. At this moment, my mother gave me a trick. She said, "Check online. You always play computer. Why don't you know how to use them? " My mother's words suddenly woke me up, and I immediately checked these two phenomena online. In a short time, I solved these two problems.
The network has supplemented my knowledge and made me make continuous progress. As I know more about the Internet, the Internet has changed my life.
I like listening to music very much. I heard from my sisters that when they were young, they couldn't afford a computer at home. When they were listening to songs, they bought some tapes and listened to them with tape recorders. It's different now. I just need a few clicks of the mouse, and good music will come. Moreover, when my sister was a child, there were many songs on those tapes, and now genuine albums are not cheap. Listening to songs online is convenient and cheap, which really kills two birds with one stone.
There are many uses in online life, such as checking some tourist attractions, which can easily choose holiday destinations; You can also check the news, as the saying goes, every man is responsible for the rise and fall of the world, so that my mother can learn more about things at home and abroad for the first time. So we can also explain the network in this way: as long as you want to know, the network can tell you and help you.
Of course, nothing is perfect, and so is the Internet. It is like a double-edged sword, which has both advantages and disadvantages. Although the Internet has great benefits for people, there are also some unhealthy things that will bring you to a terrible world and make you unable to extricate yourself.
Therefore, for some bad information, don't accept it, don't look at it, don't believe it, and don't pass it on. Because the network is a virtual world, we should always be vigilant to avoid being fooled. Only such a network is secure.

Today, we have entered an information age. Network has become an indispensable thing in people's lives. However, while surfing the Internet, we should also surf the Internet in a civilized way.
Everything has its positive side and negative side, so does the network. Internet has changed people's way of life and study. But in the network, there are some attractive games and chat websites, which bring people a lot of fun after work and study, but also bring us some harm. So we should surf the internet in a civilized way.
The network is widely used. We can look for information, learn knowledge, shop and chat online ... Although the internet has made society progress, it also has some shortcomings. Some people say that online games are electronic drugs. Once we are addicted to the internet, we will get deeper and deeper and cannot extricate ourselves. We should choose healthy web pages, which is good for us and can also avoid being eroded by unhealthy web pages. The network is virtual, and the news it tells you may be false. For example, one of your netizens said that he was a 10-year-old urchin, but he might be an 80-year-old woman. So, don't trust the internet too much. We should keep in mind the identity of students, only collect useful information and materials, consciously abide by network morality, and strive to be good teenagers in the new era.
Indulging in the internet will bring many negative effects to our physical and mental development. We should surf the Internet in a civilized way, surf the Internet in a civilized way and surf the Internet safely, and be netizens with a sense of justice, responsibility and self-motivation. To * * * maintain the network environment, * * clean up the network garbage, do not manufacture and spread network viruses, maintain network security, do not abuse and attack others online, pay attention to civilized language, and consciously resist uncivilized behavior.
We are the future and hope of the motherland, a generation with scientific consciousness and innovative ability, and the main body of network activities. We should abide by the initiative, from now on, from ourselves, self-esteem, self-discipline, self-improvement, civilized internet access, so that the network can grow healthily with us.
