I love computers. Magical computer network composition
Magical computer network The computer network is colorful. It is equivalent to an information highway, containing rich information, like a huge spider web all over the world. Every country, every city and even every home is connected.
On the computer, you can check information and easily understand the world around you; you can use your own e-mail to establish contact with children all over the world.
Computers are also a communication tool that allow us to quickly get in touch with people around us.
You can also participate in various activities such as online shopping and auctions.
With computers, our earth has become a small village, and people from all over the world can communicate at any time.
In short, it enriches our lives and brings us convenience.
Are computers really so magical? As I thought about it, I seemed to have entered a colorful computer, where I saw Mickey Mouse, Donald Duck, Sun Wukong, Hua Mulan, Calabash Baby, etc. These cartoon characters I had known for a long time were all staring at me with smiles. They also perform various interesting actions along with the music.
"It's amazing!" I couldn't help but admire.
I am proud to have this computer at home.
Thinking about how little knowledge I had when we didn’t have computers at home, I didn’t know that besides the phone at home, or the ancient ways of transmitting information: homing pigeons, fast horses, etc., there were many , I really didn’t expect that there is such a good helper for conveying information.
The basic functions of a computer are to listen to music, watch movies, and draw pictures. When you feel bored, you can play games, but you can’t play them all the time. It can’t exceed two hours at most. Playing for a long time will hurt your eyes; secondly, it will reduce your academic performance.
So we must make good use of computers. As long as we make good use of computers, computers will only have benefits and no harm.
We can learn some scientific knowledge on the computer, or conduct course tutoring, which is very helpful for our study.
With a computer, you can send e-mails to foreign friends in just a few seconds.
This can not only save paper, but also protect the global environment.

Introduction to Computer Composition
The magical "angel"---the computer. The computer is a magical guy. It can help people do many things and is very efficient! It is an assistant given to us by God. With computers we can do a lot of things! It can help us check information. If we don’t know anything about our studies, we can also ask it for advice. It is an "angel". The computer is always with us. It is giving silently, not asking for it, "giving" forever. It is more pleasant than "getting". This sentence was written by Gorky in a letter to his son. This sentence can completely describe the computer. It is such an "angel"! ~ Let me talk about myself first. Before I touched a computer, I was like a headless fly who didn’t know how to write words. Of course, I knew that looking up a dictionary was a good way, but I felt bored just picking up a dictionary. Ever since I After seeing the computer, many words can be seen by typing their pinyin. I also learned from the computer that looking up the dictionary has many benefits, so I got used to looking up the dictionary! ~ Many adults don’t approve of their children playing with computers. There are only a few reasons. ① They are afraid that their children will have poor eyesight. ② They are afraid that their children will not do their jobs and lose their ambition by playing with them (my mother is also afraid that I will play with a few). But computers are not necessarily It will only bring disadvantages, but there are also advantages, such as: checking information, listening to music, reading news, creating your own web page, and you can buy and sell things on the Internet without going out, and you can also have door-to-door delivery. Remember to do it during the summer vacation. When I didn't know a few English and proverbs, I asked my mother, but what she told me was - my mother couldn't do it either... Then my mother told me to turn on the computer and check it out... I I was only 1 year old at the time, and I didn’t know how to search for information or how to find the most accurate information. My mother told me that you can go to Baidu to find everything there, but at that time I didn’t know how to write Baidu’s website address. , I went to ask my sister. After asking, I knew that Baidu’s website address was: baidu. After I knew it, I immediately went to search for the information I wanted. As expected by my mother, I found the correct answer. I immediately copied the answer. That day I checked everything I didn’t know and didn’t know. I also checked the things I didn’t know. Now I know pretty well! ! The "angel" God gave us is my "good friend" computer. I am very grateful for the convenience it brings to us. Computers have a close relationship with us now: looking for information requires a computer, playing games requires a computer , You need a computer to chat online, you need a computer to understand information... In short, we can no longer live without computers.
Computers contain many contents, among which the international 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.
When I originally designed it, I did not think of extending the network to the whole world. I simply hoped that if a nuclear war broke out one day, there would be a network that could still reach the whole world after suffering a devastating attack. , with the ability to quickly restore smooth flow.
In the 1970s, the U.S. Department of Defense began the DARPA project and began to build high-speed and flexible networks. The key point was that if the network between the United States and the former Soviet Union was disconnected, data could still be transmitted through other Country detour to reach destination.
The result of this project was ARPANET.
Later, as the Cold War thawed, ARPANET was slowly opened to civilian use.
However, based on military security considerations, the United States also established the National Science Foundation and established NSFNET, which is responsible for global civilian network exchanges.
This is the INTERNET of the United States.
Although the United States has many rights over the Internet, for the development of science and technology, the United States itself does not charge a large amount of royalties for any behavior on the Internet (because the international Internet is paid for by the United States) Research and development), so many research institutions can join the research and development of Internet technology and services at a very low cost, and Internet has therefore developed into the world's most extensive network.
Apple and computers are two completely unrelated things. What is the reason that connects Apple and computers? In the early 1970s, microelectronic computers (microcomputers) came out. Because of their complete functions, small size and flexibility, they attracted a large number of teenagers who love electronic technology.
Near Silicon Valley, the computer base in California, in the western United States, there are two electronics fans who are only 18 or 19 years old in a small town called Cappatini.
The older man is called Steve Job. He makes a living by helping in the apple orchard on the farm while studying in college.
The younger one is called Steve Woznak. He loves music and plays with various electronic instruments. He is also an amateur in electronic technology.
The two had similar interests and became a pair of good friends who share the same brotherhood.
In 1974, some local electronics amateurs voluntarily organized a club to build microcomputers by themselves.
Job and Wozniak participated with enthusiasm.
They used an abandoned garage owned by Job's father as a studio and began to trial-produce microcomputers.
They first tried to install the microprocessor into a simple microcomputer, and then connected it with a television and keyboard to form a microcomputer system.
The operator only needs to press keys on the keyboard, and text and simple graphics will be displayed on the TV screen. This achievement was welcomed in the club, and then they tested a small batch of them and sold them to the public. , I didn’t expect that 50 units were ordered at once.
So these two young people started a microcomputer company.
In order to commemorate Job's work-study years in the apple orchard, they named this new type of microcomputer "Apple II" (Apple II), and the initial trial microcomputer It is called "Apple I".
This is the origin of Apple Computer.
Later, Apple microcomputers quickly became popular all over the world. As a result, the Apple Microcomputer Company, headed by Job and Wozniak, developed into an international enterprise with more than 4,000 people, and also established offices around the world. Many branches.
There are almost no computers today that are not equipped with a mouse. Without this cute little thing like a mouse, it would be impossible to use a large number of various software well.
So, where did the mouse come from? The formal name of the mouse should be "display system vertical and horizontal position indicator", and it is also called this in the invention patent.
It was invented in 1963 by Engelbart, a scientist at the Stanford Research Institute in the United States.
However, the most... A 400-word essay on the magical computer magician
