With the continuous development of modern science and technology, various electronic products have become an indispensable part of human beings, such as tablet computers around us.
The tablet computer is about 20cm long and 13cm wide, which is twice as big as the smart phone and three or four times smaller than the computer. Tablet computers are bigger than mobile phones, but they are very thin. Tablet computers, like mobile phones, have many brands, such as Apple, Huawei, Samsung, Lenovo and Xiaomi.
As a representative, Apple's tablet computer is also called iPad. Apple's tablet computer has been updated to the third generation. With the update, its running and memory space is getting bigger and bigger, and there are countless applications, which brings great convenience to our work, study and life.
Tablet computers are of great help to our study. If you encounter problems that can't be solved, you can open some learning-related applications such as homework help, synchronous reading, interactive learning and Baidu. Just a pat and a sweep, and the troubles caused by homework will be gone. If you are tired from study or work, you can listen to your favorite music or read a few beautiful articles to reduce fatigue.
Of course, tablets also have disadvantages. For example, today's game design is becoming more and more exquisite, and many people are addicted to games, which not only delays their study, but also leads to a decline in their eyesight. There are also many students secretly charging.
In a word, tablets have advantages and disadvantages, so we should use them correctly and reasonably.
Computers are a good helper for human beings.
The computer has a sky-blue appearance, and consists of a host, a keyboard, a display screen, a mouse and a stereo. The box next to it is the head (host) of the computer, the keyboard covered with keys is the leg of the computer, and the mouse is the hand of the computer.
Computers have many functions. At work, they can search for information, print articles and submit articles online ... They can be used to play games, enjoy music and draw pictures during leisure. ...
The computer is a big shop. People only need to open the corresponding shopping website and remit the payment through online banking. It will be received soon, which is convenient and fast. The same is true of buying books. You don't have to worry that all your favorite books in the bookstore are out of stock. As long as you enter keywords in the website that specializes in buying books, you can find them at once.
After the computer establishes an e-mail, it can easily send and receive letters and greeting cards, and it only takes two or three seconds to deliver them, which is fast and environmentally friendly.
The computer also has something called a hard disk, which can store a lot of information. The greater the capacity of a computer, the more things it can store.
Relaxation, happiness and convenience are the three characteristics of computers. But I also want to remind everyone: don't be too addicted to the internet, it will not only hurt your eyes, but also hurt your body.
On May 30th, 20XX, I bought a computer at home. Before that, my wife and I had discussed buying a computer many times. Today's society is a high-tech and information-based society, and computers have become one of the indispensable tools in our daily work. We both need computers to finish our work. Although both units have computers, other colleagues have to finish their work during office hours. Sometimes, I have to work late to go home. At that time, we considered buying a computer, but we were afraid that the children would be addicted and affect their studies. A good friend dissuaded him: "Never buy a computer, we will regret it. Children have poor self-control, adults will play games when they are not at home, and our children's academic performance will decline now! " We hesitated.
Later, my lover said, "Now many families have computers. In the future, other children can easily use computers. What should our children do if they don't know anything? " We can't stop children from walking because we are afraid of falling! "So we decided to buy it.
On June 5th, we installed broadband, and I set up my own blog for the children, so that they can keep a diary every day and practice typing and writing. But there has always been a faint worry in my heart: children will not be addicted to computers, right?
Computers are well-known electronic products, but not everyone knows computers, so I'll introduce computers to you.
Generally speaking, a computer is divided into two parts, one is a hardware system and the other is a software system.
The hardware system is tangible. They are monitor, keyboard, mouse, speaker, camera, host and so on. There are power switch, reset key, hard disk indicator light and power indicator light on the host. The power switch is the biggest button on the host computer, and its function is to turn on and off the computer. When the computer crashes, the reset button usually restarts. After the computer is turned on, the small green light of the power indicator will stay on. When reading and writing data on the hard disk, the hard disk indicator will light up to indicate the working state of the hard disk.
The software system is invisible and intangible. It controls all kinds of computer information, just like all kinds of knowledge in our brains.
Software and hardware are inseparable parts. Without anyone, the whole computer will be useless. Therefore, software is very important for computers. No matter how good the computer is, if it doesn't have software installed, it is a pile of garbage.
Computers are widely used. Just like a teacher knows a lot of knowledge. You can ask questions online if you don't understand them. Both a teacher and a friend. When we are bored, we can play games and listen to music online.
Students, after listening to my introduction, do you know much about computers?
Today, the teacher gave us homework, and asked us to write about primary school students' awareness of fire prevention, earthquakes, and prohibiting chasing and fighting on campus. Our group wants to write fire prevention consciousness, and our group doesn't know how to write it, so the group leader asks me, "Don't you have a computer at home?" You can look it up on the computer. "After school, I went home and turned on the computer to check. Sure enough, I can find it, so I copied it into my notebook.
The next day, I gave it to my teacher, who looked at it and said, "You are great, you write really well. Read it to the students. " After reading it, the teacher said, "Let's applaud." To this end, I feel very proud, very proud, not only adding a lot of color to my face, but also winning glory for the group. It's good to have a computer. Everything can be found out.
My mother is addicted to online shopping recently. She said she would buy me a skirt. I said, "Can I buy things online?" She said, "Why not buy it? As long as you fill in your home address online, you can deliver it to your door. " I don't believe it. My mother bought me a skirt. Unexpectedly, a few days later, the skirt my mother bought me online really came back and really came to my hand. I can't believe my eyes. It fits me well and looks good on me. My mother said, "I will buy clothes online in the future."
Am I right? It's good to have a computer, because it can help you do anything.
Introduction to Computer Composition 6 Science is constantly developing. Now every household has a computer that people like, and so does my family. Let me introduce you!
My computer is a LCD computer, which is a reward from my father. Dad began to observe the computer as soon as he bought it. The computer is a rectangle with a black screen in the middle. The computer can't be used without the host. There are many things in the computer: mouse, keyboard ... Computers have many uses: searching for information, typing, watching TV, reading books and so on.
One day, I was doing my homework and a topic stuck me. I used my brain, but I still can't figure it out. I suddenly remembered the computer, so I immediately ran to the computer and turned on the host. The four characters "Welcome to Use" appeared on the computer, and then the software on the computer appeared. I clicked Baidu with the mouse and it appeared immediately. I spelled my question, and then the answer I had been waiting for appeared on the computer.
Computers are also a platform for our communication. On Sunday, I finished my homework and felt bored, so I turned on my computer and qq.
This software, on my number, entered, and many good friends and classmates were chatting. I ordered a good friend to chat with him. With it, I feel that I am no longer bored and become happy.
The computer at home makes me no longer bored, and it is also a good assistant for my study.
Composition about Computer 7 Among these appliances in our family, I like that computer best!
It is really advanced, which can make our family's life, study and work more convenient and effective.
I asked why I love everything. Sometimes, my parents don't know, so let me look it up on the computer, so I can always find the answer I want. Once my mother wanted to make a big plate of braised pork, but she didn't know how to do it, so she checked the computer and found the recipe. As a result, the dishes made by computer recipes are delicious! Look, it's convenient!
I also collected some good websites, such as "composition database for primary school students", and my father asked me to exchange my writing experience with classmates all over the country online. Every Saturday and Sunday, if I finish my homework and have no friends to go out to play, I am also allowed to play small games online! I mainly play Moore Manor on it. In the manor, I became a little Moore to solve all kinds of problems. It's really fun to exercise my intelligence, but my parents are afraid that I will delay my study and my eyes will hurt my health, so I'm only allowed to play for 40 minutes on Saturday and Sunday every week!
Look, how nice it is to have a computer! You can make friends, learn knowledge and play games ... I like it!
If I were a computer, I would resist viruses, save all files and never crash.
If I were a computer, I would program the operation of TV, washing machine, air conditioner, freezer and other electrical appliances to make it more convenient for people to use.
If I were a computer, I would move the classroom home, so that students don't have to worry about homework, and all students who drop out of school can go back to the classroom to learn knowledge.
If I were a computer, I would also:
Build a rocket and finish it in a few minutes;
Clone a group of giant pandas and let their families thrive;
I can punish the bad guys, help them abandon evil and do good, and make the world full of peace.
I can kill all kinds of bacteria, keep people from getting sick and make the environment better. I can also control heaven and earth. Since then, there have been no fires, floods and earthquakes in the world.
Don't worry, what's more, after I painted on the screen for a few minutes, another earth appeared, and many extinct animals and plants came back from the dead. Haha, not bad!
If I were a computer
That's all. What if it's needed? We need to study hard, master our own skills and invent such a computer when we grow up. What if it comes true?
What I am most familiar with is the notebook computer, which is very expensive, some are worth thousands, and some are worth 10 thousand! Let me introduce my laptop to you.
Computers have many uses. Computers can type and write compositions. If you want to see photos, you can search from your laptop. There are all kinds of pictures on it, and you can find them if you want to search and rescue. Laptop can be used to chat with good friends, as long as you have Netcom in 360 software housekeeper search, then open it and enter your name to start chatting.
Notebooks can be used to play games and study. To play games, you only need to search, study and search at home in 360 software management, and it's done, ensuring that you will be addicted to learning. For example, the bag that can perform for us has pictures in it, which is particularly interesting. There are jokes in it. If you read a joke, you will burst into laughter. Macey Bao also allows computers to shut down regularly. As long as you stand alone, there will be beautiful pictures, jokes, regular shutdown and settings.

A composition about computers 10 Recently, a new friend came to our family-computers. After a few days of contact, I have some feelings with him. Now let me introduce you.
His brain is black, but in his world, only the darker the more beautiful, so my friend is not ugly.
This friend of mine is very clever. When you encounter a problem, she will always be duty-bound and patiently explain it to you. If you get a good grade in the exam, she looks happier than you, but she keeps reminding you not to be proud. Sometimes I even think there is an all-knowing elf hidden in the computer.
I know a little about his brain. Listen to the classmate, if his brain emits some strange light when it is spinning, we can use it to order food online, play games, watch TV, watch news, weather forecast and so on.
Of course, another function of my friend is that he can type. It's amazing to type with it! You can make words bigger and smaller, and you can also change the color of words. It can move left and right, and it can also change the text into different fonts ... see if it is convenient.
Although my new friend has so many benefits, you can't live without him, or he will harm you.
He has strong radiation, which is very harmful to our bodies and eyes. So we must control the time when using it.
After listening to my introduction, you know something about my friend. He is a friend that people love and hate.

It has been in my home for 10 years. After many upgrades, the functions are more and more powerful, the operation is simpler and the network speed is faster. From the appearance, it is not outstanding, and the host and keyboard are covered with dust. Although we scrubbed it many times, we still can't restore its former "youthful and beautiful" appearance. However, we don't judge a book by its cover, because it is practical, so it has become a "national treasure" of our family.
My father is a computer fan in our family. He uses the computer the longest. He always goes to QQ space to play Pirate King, QQ Farm and Ninja Village. My mother is a fan of my family. He has seen all the movies, such as Palace, Love, Truth, Goodness and Beauty and so on. I am a fan of games.

Don't worry, because you can use QQ, which is a software that can chat with others. As long as your friends are online, you can start chatting.
