Network security composition

Network security composition 1 In this era of advanced information technology, the network is very convenient, but it also hides infinite crises.

For example, taking part in the lucky draw but accidentally revealing their basic information has aroused the covet of fraud groups; Or browse unhealthy websites that you shouldn't watch, leading to computer poisoning, which is not worth the candle; It is illegal to think that anonymous messages are irresponsible, which is nonsense.

When swimming in the online world, you should pay attention to protect yourself, make an agreement with your parents about the time of surfing the internet and the website where you are, and then turn off your mobile phone. Don't spend too much time surfing the Internet, and take a ten-minute break every half hour to avoid myopia. Don't be too addicted to online games and let your homework plummet. These are all good ways to protect yourself!

I hope everyone can swim safely and happily in the online world!

With the development of information technology, computers are becoming more and more popular, and the network has already become 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 that 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.

Network security composition 3 "Wow! My computer time is up. " I ran to the computer desk in high spirits.

I remember when I just bought the computer, my brother and I scrambled to play. Because of this, my brother and I started a war in enter the dragon. We fought to the death, but we were all smiling. My brother often plays video games and games online, and I often look up information and chat with netizens online.

I remember once, when we were ecstatic, suddenly, the computer stopped, and I was afraid of poisoning and burst into tears. I still remember one time when I was playing games online, I was really poisoned because I downloaded the games casually, which was not worth the loss. After that heavy blow and lesson, I dare not download it casually any more. I became more cautious to avoid being poisoned or hacked, which was a terrible loss!

My mother told me that as long as I don't download games and take good care of my computer, it won't be easy to be poisoned and crash. Things to pay attention to when surfing the internet, such as: pay attention to whether there is fraud or virus in that website, and don't download programs indiscriminately. There are hidden dangers everywhere in the computer network world. We should be careful to prevent this incident. Personal data should be kept confidential to avoid computer poisoning, and others should be prevented from abusing our data to do evil, which is out of control.

There are good and bad worlds in computers, so we should pay attention to the safety of computers carefully to avoid being hooked by hunters. In the computer world, I have learned a lot of knowledge, and also learned a lot of things that need attention. I want to share it with my classmates and become a happy computer expert.

Network security composition 4 I believe that all students can use computers and surf the Internet! But now the network will inevitably appear some errors, superstitions and pornographic content. How can we avoid them? What do some technical terms on the Internet mean? What should we do when surfing the Internet? As long as you study the book Network Security and Morality, you will certainly find the answers to these questions that ordinary primary school students will ask.

After reading the book Network Security and Morality, I can feel that the network has really brought great convenience to our lives. For example, you can find information and shop on the computer. On the Internet, you can learn about state affairs and see the latest news. What makes children happy most is that they can play online games ... From the online encyclopedia part of this book, I learned some little knowledge about computers, which made me understand many problems that I don't know much about computers at once.

However, everything has two sides. Although computers have many advantages, they also have many disadvantages: for our primary school students, excessive addiction to online games will bring great harm to our physical and mental health. Sometimes you will be caught off guard by the virus in your computer. Now let me tell you how to prevent the virus from harming the computer itself. You'd better install a security firewall in advance. A "security firewall" is a protective measure for computers to resist virus invasion, which can ensure the normal operation of computers. Everyone thinks chatting online is a good thing. Although I think so, I find that some people will bring dirty words when posting. What should I do? The Network Security and Ethics Reader tells us that we should stop them immediately or tell the moderators to delete their posts. Internet is a modern means of communication, which has created a broad platform for us to learn and communicate, but its virtuality and anonymity have also given some malicious bad guys an opportunity. Seeing that we minors have little life experience, weak ability to judge right and wrong, strong curiosity and other psychological characteristics, they took the opportunity to enter and cheat and hurt us minors by various means. Therefore, we must be clear-headed and correctly understand the two sides of the Internet.

Therefore, I think that as a primary school student in the new era, we should make rational use of the internet to serve our study and life, and pay more attention to being a civilized little netizen, not surfing unhealthy internet, reading unhealthy information and indulging in online games! I believe you will gain a lot after reading this book!

For me with developed limbs and simple mind, there is one of the most precious treasures around my life, and that is my "multi-star"-computer.

Since I have a computer, I will sit in front of its square screen every holiday, holding the control mouse in one hand and manipulating the keyboard in the other, staring at the ever-changing picture on the computer screen with two eyes. How happy I am! But I remember one time. ...

"dad! My computer has a concussion again! " I cried loudly.

dad

Said: "How is it possible! I just fixed it last month. How did you break it? How hateful! " So our father and son had a good talk, and I quarreled for thirty minutes. Finally, my father decided to call a computer engineer to repair the computer.

After the engineer came, as soon as the computer was turned on, a lot of messy words appeared on the screen, which made people see things in a blur. The computer doctor told us: "This computer is poisoned by software." Five minutes later, the computer doctor opened the main chassis and turned to us and said, "The hardware of this computer is dead!" " "wow! Why ... My heart sank to the bottom. It took the computer doctor nearly two hours to cure my baby. The computer engineer told me not to download things I don't know casually, and not to open letters and documents of unknown origin, otherwise my brain would turn into a pig brain ... I suddenly realized!

I hope everyone can become a doctor of computer science, but you must abide by the rules of using computers, and computers will certainly thank you. Otherwise, like me, I will be scolded and liked.

pig

The head is the same, although I am not convinced, but this is also asking for it!
