I like computers.

The magical computer network is rich and colorful. It is equivalent to an information superhighway, rich in information, like a huge spider web all over the world, connecting every country, every city and even every family.

In the computer, you can easily access information and understand the world around you; You can use your e-mail to establish contact with children all over the world.

Computer is also a communication tool, which enables us to get in touch with people around us quickly.

You can also participate in online shopping, auctions and other activities.

With computers, our earth will become a small village where people from all over the world can communicate at any time.

In a word, it enriches our life and brings us convenience.

Is the computer really that magical? After thinking about it, I seem to have entered a colorful computer. Inside, I saw Mickey Mouse, Donald Duck, the Monkey King, Mulan, Huluwa and so on. These anime characters I have known for a long time are all staring at me with smiles and making all kinds of interesting moves with the music.

"It's amazing!" I can't help admiring.

I am proud that we have this computer at home.

Think about how shallow my knowledge was when there was no computer at home. I didn't know there were many ways to send messages at home besides telephone, such as homing pigeons and fast horses. I didn't expect such a good helper to deliver information.

The basic functions of computers are listening to songs, watching movies and drawing pictures. You can play games when you are bored, but you can't play like that for more than two hours at most. Playing for a long time will hurt your eyes. Secondly, it will reduce academic performance.

So we should make good use of computers. As long as we make good use of computers, computers will only have advantages, not disadvantages.

We can learn some scientific knowledge on the computer or give course guidance, which is very helpful for our study.

With a computer, you can send emails to foreign friends in a few seconds.

This can not only save paper, but also protect the global environment.

What a good computer!

A wonderful computer consists of a monitor, a speaker, a mouse, a keyboard and a host computer.

The display shows patterns, the speaker makes sounds, the mouse and keyboard can give orders, and the most important thing is the brain of the computer.

Computers have many functions.

For example, playing games, typing, chatting, or drawing, looking up information ... What I like best is the drawing function, and Kingsoft Painting King software is very powerful. You just need to choose a few kinds of flowers and use the mouse casually, and those flowers will bloom one by one, which will dazzle you and make you like it to death.

How's it going? Good enough? What's even more amazing is that it can make animals and characters move and make the picture colorful, vivid and interesting.

The computer is also like an expert who knows everything. As long as I have something I don't know, it will help me find the answer.

What a great computer!

Who can tell me an article about magic computers? The teaching goal of magic computer network (1). Understand what a computer network is.

(2) Be able to distinguish the difference between local area network and wide area network, and have a preliminary understanding of them.

(3) Being able to learn e-mail and network information * * * Being able to have a perceptual knowledge of the network and Inter at the same time.

Concept and function of key and difficult network.

Teaching process 1. Introduce students. As we have just started to learn computers, we have learned a lot of computer knowledge and many application software into our brain's "memory".

But today, with the continuous development and popularization of computer technology, more and more computers have entered a new "world". In this world, all computers are integrated, and no computer is isolated. They can exchange information with each other, transmit information and appreciate documents, and turn the remote ends of the earth into a world close at hand! This is the magical computer network. Let's take a look at what a computer network is and why it is so magical.

Second, new teachers show the campus network structure through projection or screen, and show multimedia films introducing computer networks.

1. Computer Network According to the structure diagram of the campus network, it is introduced to students that connecting multiple computers through communication lines is called computer network.

2. Computer network types Show slides and introduce students to several common computer network types: local area network, wide area network and Internet.

3. The role of computer network shows the role of computer network to students through examples of multimedia movies and surfing the Internet.

(E-mail, LAN operation) Third, students practice in the classroom (1) to find the nearest computer and the farthest computer on the network.

(2) Copy a file from the teacher's computer to his own computer.

Introduce the magical "angel" of computer composition-computer is a magical guy, it can help people do many things, and it is very efficient! It's an assistant from God. With computers, we can do many things! It can help us to look up information, and we can also ask it to be an "angel" if we don't know it in our study. The computer has always been with us, and it is quietly giving, not taking. Giving is always more pleasant than taking. Gorky wrote a sentence in his letter to his son, which can completely describe the computer. This is the "angel"! ~ Let me talk about myself first. Before I touched the computer, I was like a headless fly who didn't know how to write. Of course, I know it's a good way to look up the dictionary, but I just feel tired of picking up the dictionary. Since I saw the computer, many words can be seen through pinyin. I also learned from the computer that looking up a dictionary has many advantages, so I am used to looking up a dictionary! ~ computers many adults don't agree with children to play, and there are only a few reasons. They are afraid of their children's poor eyesight. They are afraid that their children will not do the work they should do and play with things (my mother is also afraid that I will wear some clothes), but computers may not only bring disadvantages, but also have some advantages, such as searching for information, listening to music, watching news, setting up their own web pages, and buying and selling things online without going out. It can also be delivered to your door. I remember that summer vacation, I asked my mother how many English and proverbs I didn't know, but what I told me was-neither did my mother ... At this time, my mother asked me to turn on the computer to check ... I was only 1 year old, and I didn't know how to find information and how to find the most correct information. My mother told me that you can go to Baidu to find anything. But at that time, I didn't know how to write Baidu's website, so I asked my sister. I didn't know the website of Baidu until I asked: Baidu. As my mother expected, I found the right answer. I copied the answer at once. That day, I checked everything I didn't know, and I also checked what I didn't know. Now my knowledge is good! ! God gave us an "angel", that is my "good friend" computer. I am very grateful for the convenience it has brought us. Computers are closely related to us now: we need computers to find information, play games, chat online and learn information ... in short, we can't live without computers.

Computers contain a lot of content, among which the Internet has spread all over the world.

It is also called inter, and its original source is a military network of the US Department of Defense.

I didn't think of bringing the network to the whole world when I designed it. I simply hope that if a nuclear war breaks out one day, a network will be able to spread all over the world after a devastating attack and have the ability to quickly restore smooth flow.

In 1970s, the U.S. Department of Defense began to implement the DARPA plan to build a high-speed and flexible network. The key point is that when the network between the United States and the former Soviet Union is disconnected, data can still bypass other countries to reach their destinations.

The result of this plan is ARPANET.

Later, with the thawing of the Cold War, ARPANET was slowly opened to the public.

However, based on the consideration of military security, the United States has also established the National Science Foundation and NSFNET, which is responsible for global non-governmental network exchanges.

This is the internet in America.

Although the United States * * * has many rights to Inter, for the development of science and technology, the United States itself does not charge a large amount of patent fees for any behavior on the Internet (because the Internet is developed by the United States * * *), so many research institutions can participate in the research and development of Inter technologies and services at a very low cost, and Inter has thus developed into the most extensive network in the world.

Apple and computer are two unrelated things. What is the reason for connecting Apple with computers? In the early 1970s, microcomputers (microcomputers) came out, which attracted a large number of teenagers who loved electronic technology because of their complete functions and portability.

There are two electronic fans who are only eighteen or nineteen years old in a small town called Capati near Silicon Valley, the computer base camp of California in the western United States.

The older one is Steve Jobs, who helped make a living in the apple orchard on the farm during his college study.

The younger one is Steve Wozniak. He likes music and plays all kinds of electronic instruments. He is also an amateur of electronic technology.

They are like-minded and become a pair of bosom friends.

From 65438 to 0974, some local electronic amateurs spontaneously organized and set up a club to make their own microcomputers.

Job and Wozniak joined in with great interest.

Using an abandoned garage of Job's father as a studio, they began to trial-produce microcomputers.

They first tried to assemble a microprocessor into a simple microcomputer, and then connected it with a TV set and a keyboard to form a microcomputer system.

As long as the operator presses the key on the keyboard, text and simple graphics will be displayed on the TV screen. This achievement was welcomed by the club, and then they tried to install a small part of it for public sale. I didn't expect to order 50 sets at once.

So, these two young people started a microcomputer company.

In order to commemorate Job's work during his work-study program in the apple orchard, they named this new type of microcomputer "Apple Ⅱ", and the first trial-produced microcomputer was called "Apple Ⅰ".

This is the origin of Apple Computer.

Later, Apple-type microcomputers quickly became popular all over the world. Apple Microcomputer Company, headed by Jobs and Wozniak, developed into an international enterprise with more than 4,000 people and set up many branches all over the world.

Nowadays, there are almost no computers without mice. Without a cute little mouse, a lot of all kinds of software can't be used well at all.

So, how did the mouse come? The normal name of the mouse should be "the vertical and horizontal position indicator of the display system", which is also called in the invention patent book.

It was invented in 1963 by Engelbarth, a scientist from Stanford Research Institute.

However, this is the most ...

Nowadays, many families have computers, and it is precisely because of their many functions and uniqueness that they are favored by people. Let me introduce the unique functions of the computer. First of all, computers can help people solve some problems they don't understand, and they can also complete some tedious business on computers.

Secondly, you can listen to music, play games and relax on the computer after work. More importantly, computers can receive messages from all directions, so that people can know what is happening in the world at the first time, and truly realize that "scholars don't go out, and the world knows it." The function of the computer is far more than that. With the needs of people's life, computers are endowed with more and more functions. Fold the flowers to meet the courier and give them to the faucet.

In ancient times, people wanted to send greetings to distant relatives and friends, mostly relying on long-distance postal services. Until 1993, the United States proposed to build an "information superhighway" on computers, so that people can receive words, sounds and images from anywhere with a click of the mouse at home. Even more amazing is that the "information superhighway" can make people thousands of miles away become friends. The magical function of computer can't be explained clearly in a few words. In a word, the computer has become an indispensable part of people's life, and it is also an indispensable part of my study and life. I believe that in the near future, computers will enrich the world and enhance people's friendship!

One day in 2026, the hall of the computer company I founded was crowded with people. It's a sea of people

Wow, so many people came to snap up the supercomputer I invented.

Why is my computer so popular? Then let me introduce it to you.

First of all, its appearance is attractive. It is only the size of a notebook, with a color-changing shell, elegant and noble display and colorful indicator lights ... which makes people fondle it.

Next, I'll introduce you to the components of the supercomputer I invented! The processors of ordinary computers that people usually use are mostly Pentium 4/5, and now the fastest one is Pentium 6, and the processor used in the supercomputer I invented is equivalent to the future Pentium 60, which is awesome enough! Its memory also far exceeds that of ordinary computers, and its memory is 10 times that of ordinary computers.

After I introduced the appearance and components of the supercomputer, it's time to tell you the functions of the supercomputer.

What should I do if I am in a bad mood? Don't be afraid. Supercomputers can make you happy. You will definitely say: joke, how does the computer know your mood? Not necessarily, because the supercomputer I invented is equipped with a mind sensor, which can judge your mood through your brain's thinking, and then display corresponding sentences, making you feel that the supercomputer is like an understanding good friend.

Its movie programs are also amazing. If you want to see a movie, you can watch any movie just by opening movie program.

And open the homemade movie program, you can completely walk into the movie world, you can be both the protagonist and the director.

Supercomputers are not only powerful, but also surprisingly energy-saving, you know? It only needs a No.5 battery and can be used continuously for ten days. It's amazing! Seeing such a powerful computer, you will definitely feel expensive, reaching tens of thousands of yuan.

But in fact, you can buy it for only 5 thousand yuan, and now you can get a discount. Do you think there will be so many people snapping up? This is a supercomputer that I invented. How's it going? Not bad? Primary school students' supercomputer composition 600-word composition (/)

For example, taking you through time and space to help improve your academic performance ~ this is a bit outrageous. Imagine composition 1. It should be based on basic facts, which are closely related to life. For example, if a mother gives birth to ten kittens, the universe is smaller than the earth, which is not in line with real life. 2. Imagine that if we are magical and exaggerated, we can play freely. For example, we can let small animals live like people and let themselves walk into candy. You can also approach the future world. 3. Imagine that the theme of the composition can be calling for environmental protection, praising maternal love, promoting kindness and imagining the future. ~ I hope these can help you, and I hope to adopt them!
