10 years ago, all the manuscripts written by computers were stored on floppy disks, and an ordinary 3.5-inch disk could store about 700,000 words. But the reliability of this disk is not very high.
Now, CD burning, USB flash drive and mobile hard disk storage have become the main ways to save materials. Their storage capacity is thousands of times that of previous floppy disks, and even illustrated manuscripts can be safely stored.
At the same time, the unit storage cost is also greatly reduced. The greatest convenience of writing with a computer is that you can quickly print out some or all manuscripts with a printer at any time.
A million-word manuscript can be printed in a few minutes, with clear images and neat words. If this job is copied by hand, it must be time-consuming and error-prone.
After editing and processing, the contents of the manuscript will be arranged by the computer according to the prescribed format, and then the film will be printed by the laser imagesetter, and then printing can be carried out.
2. the benefits of writing a computer are our good friends' computers.
We have a very close friend who has a flat brain and a cube brain. It knows everything from astronomy to geography. Ask it if you have any questions, and it will definitely give you a satisfactory answer. This is a well-known computer.
Computer! But this is amazing. There are many things in that little head. Chinese, math, English ... everything. Not only that, if you want to know some news, you can also find it on the computer, which is convenient.
Computers have many benefits! Wanderers can't go home, so they can chat with relatives on the Internet to find out about the situation at home. People who have worked hard all day can watch jokes, play fun games and relax for a while on the computer. You can also go online to see some information, understand state affairs and care about the country. Watch the news and know some recent things. When there is no computer, you don't have to ask if you want to know such a question. It's good to have a computer! There are still many benefits waiting for you to understand!
But don't be too happy, everything has its shortcomings, and computers certainly have them. Playing computer for too long will make you wear ugly glasses and turn into four eyes. And sitting on the computer for too long, the bones will ache, and you will get spinal diseases, which is very uncomfortable. I don't think you want this!
Computers have both advantages and disadvantages. We must make full use of many things that computers know to make contributions to mankind. Don't use it on bad things.
There is a composition about the advantages of writing computer. In this 2 1 century, when high technology is developing, we must learn a lot of knowledge to keep up with the pace of society. Now the law of "illiteracy" is that we should not only learn what we want to learn, but also learn computers well. The computer has brought me into a new world. Computers have played a great role. Students often use them in their work. Of course, we will also use it in our study. My English is not good, so I often don't know how to learn English well. We should learn computers well and know that computers can search the information we want. I turned on the computer and typed in "How to learn English well". Soon many articles about learning English came out. You see, it can be found in less than a minute. It would be very useful if I went to the library to look for it. The computer helped me learn it well. Computers span the whole world, and families can learn the governance that is beneficial to families. With them, we can understand the customs, culture and views on some things there. Middle school students should learn some cultural knowledge. All computers are connected. For example, we can enter the international chat room and stream in English, which can exercise my ability. I have a cultural exchange with a beautiful girl, which let me know that their family is very developed and their life is very rich. Computers are very advanced, which makes us feel novel. In the medical field, computers have played a great role. In medicine, doctors use computers to help them treat diseases. Some of them need very delicate surgery, but now they don't need surgery. All they need is a computer to treat diseases. Many scientists have done many important experiments with computers. Just like SARS, scientists use computers to analyze and learn the origin of SARS and extract it. Many scientists use computers, and many accurate figures can only be obtained by computers. In some developed cities, teachers don't have to give lectures in school classes because they all use computers. This is also very representative! The computer is my friend, my second teacher, and it led me into another new world.
Advantages of computers Nowadays, with the development of social science and technology, the use of computers has become very common. Almost every family has a computer. Computers are widely used, convenient and fast, and are well received by people, but they also bring many disadvantages. Computers have many advantages, such as being convenient for us to collect information. When we want to do a special project, but lack of information, as long as we surf the Internet, we can find a lot of information related to the special project immediately, which is very convenient. Students' language ability can be improved by computers. Now there is a "one a day" reading plan on the Internet. We only need five to ten minutes every day to read a high-quality article and finish after-school exercises. If this goes on, our Chinese level will certainly be greatly improved over time. If students encounter something they don't understand in their homework, as soon as they get online, someone will solve the problem for us.
However, computers have also brought us great shortcomings. If we watch the computer for a long time, will the computer affect our eyesight? The computer screen does not allow our eyes to have proper rest, which will affect our vision, lead to myopia, and more seriously may lead to "dry eye". It will also affect our studies. If we are too addicted to online game lines and "ICQ" and neglect learning, our academic performance will decline, or even we have no intention to learn. However, the most serious thing is that it affects the communication between people. Because computers are so inconvenient, people can only transmit information to each other through the Internet, and even the time for connecting to the phone is reduced. If this goes on, this society will become indifferent and the gap between people will become bigger and bigger. Alas! How terrible the harm brought by computers is!
"Water can carry a boat, but it can also overturn it." I firmly believe that as long as we know how to beat ourselves, allocate time and make good use of computers, computers will become a good helper in our lives.
5. The use of computers I have a special feeling for computers. Computers are omnipotent to me. Usually I don't know anything, or look up information. This teacher and computer can answer me as soon as I ask a question. Yes, it can comfort me when I am unhappy; When I miss my brothers and sisters studying abroad, it can let me see their every move at once. So I especially like computers. Although computers have so many advantages, they just don't like my mother. She told me to play less computer every day. One day, my mother called me over and said, "Come, look at this article. Write the same as your primary and secondary school students. " "What's the matter, so nervous?" I asked, puzzled. "Don't be serious, let's take a look at this article." My mother said seriously. "I thought it was an article. Why all the fuss? " Oh, no, my mother must have borrowed another article to enlighten me. I thought to myself. After reading the newspaper, I said disdainfully, "What's so strange about this? Very normal. " "Do you know normal? I often read such articles in newspapers. You should pay attention. In the future, you should surf the Internet less, and you'd better not! " I want to refute, but I know my mother's temper. I said "yes" and went back to my room. I think about what my mother just said over and over again, which makes me feel funny and strange. Why can't my mother even figure this out? Computers are so useful, how can they not be used or used less? How can she compare with me who are crazy about playing legends? I'm not the kind of person who is addicted to computer games. In addition, as the teacher said, everything has two sides, no harm, no gain. As for us, we should see the bright side. Computers have both advantages and disadvantages. We should make good use of them instead of destroying their "image" in people's minds.
6. Write an article about the benefits of computers Advantages of computers: Computers are widely used, convenient and fast, and are well received by people, but they also bring many disadvantages.
Computers have many advantages, such as being convenient for us to collect information. When we want to do a special project, but lack of information, as long as we surf the Internet, we can find a lot of information related to the special project immediately, which is very convenient.

If students encounter something they don't understand in their homework, as soon as they get online, someone will solve the problem for us. Computers can let us know a lot of extracurricular knowledge, and teachers let us look up information. If there are no books, we can use the computer, which is convenient and practical.
For example, shopping, booking air tickets, etc. can be ordered by computer now. You can also make slides. Blog computers can also control production and transmit information.
1. Analysis of the current situation of middle school students using computers: In today's society, computers are developing by leaps and bounds. Almost every family in the city has a computer, and we can't live without it. As a "new generation", computers are an indispensable part of our study and life.
Through the investigation of classmates around us, our project team members believe that middle school students use computers mainly for the following purposes: learning (including drawing and writing), playing games (including listening to music and watching movies) and surfing the Internet. The main uses of surfing the Internet are: online learning, searching for information, playing games (including listening to music and watching movies), chatting and making friends.
According to statistics, playing games accounts for the largest proportion, almost reaching more than 60%. Second, the positive role of computers in the growth and progress of middle school students: At present, the use of computers by middle school students is very common, but it has advantages and disadvantages. Computer is easily accepted by our middle school students, and its advantages are: 1, which is an important way to master all kinds of knowledge quickly. Computers have become an important source of knowledge.
Most of the materials of the world's major libraries can be obtained online through computers, which is not only quick to consult, but also saves a lot of extra expenses. There are also news, materials, entertainment, literature and other information.
Through the computer, we can see the latest, fastest and most authoritative news on the Internet, learn knowledge that books don't have, and learn a wider range of unknown information, so that more middle school students can get close to the forefront of science and technology faster and earlier, and let us love and admire science more. 2. Effective ways to receive education The current learning software is dazzling and much more interesting and flexible than books. Just like watching cartoons, it is easy to attract our attention.
A few thick encyclopedias of Britannica and a small CD can do it. There is also a new teaching method of "online school", where teachers teach you individually and "classmates" learn from each other in communication, completely getting rid of the shackles of face-to-face with teachers in class and being free from the constraints of time and place, which is of great help to our middle school students to play freely.
Computer is a useful tool to strengthen communication. Nowadays, almost all middle school students are only children. Except at school, we usually spend more time alone. We can chat in chat rooms or OICQ and other communication websites through computers. In this virtual world, we can talk about our favorite topics. Netizens, regardless of age or occupation, can express their feelings as long as they think they are like-minded.
This is an excellent opportunity for us who are eager for friends, friendship and talk. We talked happily in the internet and got spiritual relaxation and relief.

Disadvantages of computers .. 1, computer radiation pollution will affect the circulatory system, immunity, reproduction and metabolic functions of human body, seriously induce cancer and accelerate the proliferation of cancer cells in human body.
2. The cardiovascular system affecting people is characterized by palpitation, insomnia, menstrual disorder, bradycardia, decreased cardiac blood volume, irregular sinus heart rate, leukopenia and decreased immune function of some women. 4. It has a bad influence on people's visual system. Because eyes belong to the sensitive organs of human body to electromagnetic radiation, excessive electromagnetic radiation pollution will also affect the visual system.
Mainly manifested as decreased vision, causing cataracts and so on. . .
In fact, the quality of the computer is absolute, just as we have learned in physics, absolutely static objects do not exist. Similarly, the quality of computers is relative. If we are good at using it in a good way, then the home computer is obviously good for everyone.
But on the contrary, if you are not good at using it, or even use it to do some bad things, then naturally, computers are not good for everyone. So I think the advantages and disadvantages of computers that we have repeatedly discussed are relative.
Therefore, the computer is neutral, there is no difference between good and bad, it depends on how you use it.
7. The function and function of the computer combination computer, also known as electronic computer, is a scientific and technological achievement invented by scientists after years of research. After several generations, electronic computers have become computers with multimedia functions. Nowadays, computers have entered thousands of households, and our relationship with computers is getting closer and closer.
Last year, I also bought a computer at home, which brought a lot of convenience to my family and broadened my horizons.
My father is a teacher. Every time you grade a paper, you must calculate the students' rankings and scores. Every time I see my father marking papers and calculating scores late into the night, I feel sad. I only blame myself for being stupid and not helping him. Dad hasn't been so busy since he bought a computer at home. All he has to do is tap the number keys a few times, and a set of accurate data will appear on the fluorescent frequency of the computer, thus saving Dad two-thirds of the time.
Computers can surf the Internet, and the content on the Internet is more colorful. You can find your favorite books and articles on the bookshelf. In the chat room, I can say whatever I want. By talking about the topics I want to talk about, I can make more friends and understand other people's personalities. You can watch TV programs in the movie room, including series, old movies, and * * * movies that are deeply loved by our children. You can relax and enjoy a good time by watching your favorite programs.
In the 2 1 century, computers were used not only in families, but also in many units and enterprises.
On Sunday, I visited my mother's unit, the library. There are four floors here, and each floor is managed by a computer. If the reader fails to pay the fine within the time limit, the computer will automatically lock the reader's library card, but it cannot be completed. But if the reader is punished, the computer will automatically unlock the reader.
Now that technology is developing rapidly, I firmly believe that computers will have greater development in the next few years!
