According to statistics, the time spent playing games accounts for the largest proportion, almost reaching more than 60%. Second, the positive effect of computers on the growth and progress of middle school students: At present, the use of computers by middle school students has been a very common thing, but there are advantages and disadvantages, computers are easy to be accepted by our middle school students, and its advantages are mainly manifested as:

1. It is an important way to quickly master a variety of knowledge Computer has become an important way to acquire knowledge. Most of the materials in the world's major libraries are available online through computers, which is not only fast but also saves a lot of additional costs. There is also a variety of information such as news, materials, entertainment, literature, etc.

Through the computer on the Internet, we can see the latest, fastest and most authoritative news, learn knowledge that is not in books, and learn a wider range of unknown information, which also enables more middle school students to get closer to the frontier of science and technology faster, earlier and closer, so that we love and advocate science more. 2.

The computer is divided into, controller, combinator, memory, output input device, four major pieces, connected together by the bus, the controller is the consciousness in the human brain, giving commands, the operation of the whole electricity has to pass its instructions, calculators, is to calculate all kinds of data, and CPU, is a combination of combinators and calculators, equivalent to the human head, all the instructions and most of the calculations in the computer are completed by it, of course, with the development of science and technology more and more superb, now, the display aspect, Graphics cards have appeared, and graphics cards can automatically summarize most of the display calculations, and then transfer them to the CPU, and then collect the CPU for secondary calculations. This greatly reduces the number of CPU workloads. So as to increase the speed of the whole machine.

The speed of the CPU is very important in the computer, the speed of U directly determines the speed of the computer to calculate all aspects of the data, that is, the speed of the computer operation, of course, a good CPU, but also other good hardware to cooperate, in order to become a high-performance, just like a doctoral student's head, if it is on the body of a baby who can't even speak, it will not play much role.

Whenever my classmates talk about their experience of surfing the Internet, those who often surf the Internet are always talking with great interest, and I can only silently share the happiness of others on the side, I really envy them! One day during the summer vacation, I told my dad that I wanted to go online, and my dad agreed, and I jumped three feet high in excitement. I really didn't expect that the next day, the staff of the local broadband service center helped us connect to the broadband network.

That's when I really saw our own broadband. The broadband network first met my requirements, I no longer have to go to the bookstore to buy books under the scorching sun, as long as I turn on the computer, enter a few letters, and then click a few clicks of the mouse, you can find a lot of books on **, and there are more "Internet", "China Children's Network", "Red Mud Village" and so on, it is really everything, much more convenient. That's when Dad thought:

There are pages for children to see, but aren't there pages for us adults to see? It seemed that my father did not really understand the purpose of the Internet, so when Dad told me his thoughts, I pretended to know very well and said, "The content on the Internet is rich and colorful, not only children can find the electronic newspapers and magazines they need, but adults will also be able to find all kinds of information they need!"

He will be suspicious, only to see that after I entered the Zhoucun **net**, the screen immediately showed what Dad wanted to know, and after a few clicks of the mouse, those news articles were immediately displayed in front of our eyes, I found the "Zhoucun District SARS Prevention and Control Advanced Individual and Advanced Collective Commendation Conference", "Safety Report"...The variety of stories is very interesting, and they are all very lush. Soon, my mother also joined our online life, and often watched some TV dramas on the Internet, and the computer gradually became more important than the TV because of the entry of the Internet. It's been so much fun to live online this summer!

After surfing the Internet, I feel like I have a pair of clairvoyance, and I can see any information.

Disadvantages of computers:

One: There is radiation, which will hurt ** and eyes!

Two: Online games on the computer will be intoxicating! Not only is this a waste of time, but it also wastes our money!

Three: Computers will make people sluggish, make people reluctant to use their brains to think about problems, and make people not willing to use their hands to communicate with friends!

Four: Computers can make people (35 people) inhuman, lose patience and kindness!

The pros and cons of computers.

In today's society, the use of computers has become very common, and almost every household has a computer.

The computer has a wide range of uses, and it is convenient and fast, and it is very popular among people, but at the same time, it brings a lot of disadvantages to the evil group: the computer will affect our eyesight, if we look at the computer screen for a long time, do not let the eyes take a proper rest, which will affect our eyesight, lead to myopia, and more serious may lead to dry eye disease. It can also affect our academics, and if we get too caught up in online games and ICQs, we will ignore our studies, and our academic performance will drop as a result, or even be unmotivated.

However, the most serious thing is that it affects the communication between people, because the computer is too inconvenient, people can only use the Internet to transmit messages between each other, and even the time of connection ** has been reduced; In the long run, this society will become apathetic, and the barrier between people will become wider and wider. Alas! How terrible the harm of computers is!

I firmly believe that as long as we know how to overcome ourselves, know how to allocate time, and make good use of computers, then computers will be a good helper in our lives.

When you see this, you may ask, how can the computer make me happy and worry at the same time?

Isn't that inconsistent? However, the computer really makes me happy and sad at the same time! Come and see!

One Sunday, I was looking at the computer boringly, and suddenly, there was a ** called "While Playing the Game"! I'm curious, how can I play a game and write at the same time? Yu Fu did yes,I clicked on this ** with a curious mood,。

Let's remember.

Writing. On Monday, the teacher said, "Let's do an essay in this class!" The subject matter is not limited, and the topic is self-proposed.

Okay, get ready! Begin! As the teacher shouted, only the rustle of writing was heard. I was thinking hard when suddenly I saw me.

Sunday. The scene you saw, good! That's it!

Within a few minutes, I handed my "freshly baked" essay to the teacher, who looked at it and said to the class, "Guys, I think this essay is very well written, I deserve a perfect score for her!" When I heard this, I was overjoyed.

After school, I showed my perfect score essay paper, and my parents smiled sweetly.

After that, every time my parents disagreed with my lack of balance on the Internet, I would take out my bright red one.

Full marks for essays. Show them, and they will have to agree. But because of my frequent Internet access, it leads.

Decreased vision.

The function of the computer depends on the computer software, for example, if the computer has Word installed, you can perform word processing operations, if Photoshop is installed, you can carry out **(**) retouching processing, if you install game software, you can play games.

There are many daily functions, such as online learning, entertainment (more, watching movies, listening), playing games, checking information, etc. (These can all be done at the same time).

It also plays a very important role in the work: such as improving production efficiency, (paperwork, writing, accounting statements, industrial drawing, leaf making, etc.) can make us no longer use paper.

Nowadays, computers are very comprehensive, and some can even replace people to work, (such as automatic operation) These functions are endless, and only when they are used can they be experienced.
