The magical "angel"---the computer
The computer is a magical guy. It can help people do many things and is very efficient! It is the assistant given to us by God. . With computers, we can do a lot of things! It can help us look up information. If we don’t know anything about learning, we can also ask it for help. It is an "angel". Computers are always by our side, and they are silently teaching us. It is dedication rather than asking. "Giving" is always more pleasant than "taking". This sentence was written by Gorky in a letter to his son. This sentence can completely describe the computer. It is such an "angel"!~ < /p>
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 just picked up a dictionary and It feels boring. Since I saw the computer, many words can be seen by typing the pinyin. I also learned from the computer that looking up the dictionary has many benefits, so I got used to looking up the dictionary!~
Computer Many adults don’t agree with their children playing, and 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 things (my mother is also afraid that I will play with a few). But computers do not necessarily only know how to play. It brings 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 leaving home, and you can also have door-to-door delivery.
I remember during the summer vacation that I didn’t know a few English and proverbs, so 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. Look it up... 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 correct information. My mother told me that you can go to Baidu to find everything, but I didn’t know it at the time. How to write Baidu's website address, I asked my sister, and after asking, I knew that Baidu's website address was:
www.baidu.com As soon as I found out, I went to search for the information I wanted, and it didn't go as planned by my mother. I really found the correct answer. I immediately copied the answer. That day I checked everything I didn’t know or didn’t know. I also checked the things I didn’t know. Now what I know is considered Not bad!!
The "angel" God gave us is my "good friend" computer. I am very grateful for the convenience it brings to us.

Computers are now closely related to us: we need computers to find information, we need computers to play games, we need computers to chat online, we need computers 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 the Internet, and its original source is a military network of the United States 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 travel around the world after being attacked by a devastating attack and have the ability to quickly restore traffic. . In the 1970s, the U.S. Department of Defense began the DARPA program 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 routed through other countries to reach its 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 American INTERNET. Although the U.S. government has many rights over the Internet, for the development of science and technology, the U.S. itself does not charge a large amount of royalties for any behavior on the Internet (because the U.S. government funded the research and development of the international Internet), so many research institutions, Being able to participate in the research and development of Internet technologies and services at a very low cost, the Internet has also been able to develop into the most extensive network in the world.
Apple and computers are originally two unrelated things. What is the reason that connects Apple and computers? In the early 1970s, microelectronic computers (microcomputers) came out. Because of its complete functions, compactness and convenience, it has 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 one is named Steve Job. He makes a living by helping in the apple orchard on the farm while studying in college. The younger one is named Steve Wozniak. He loves music and plays with various electronic instruments. He is also an amateur in electronic technology. The two had similar interests and became 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 enthusiastically. They used an abandoned garage owned by Job's father as a studio and began to trial-produce microcomputers. They first tried to assemble 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 the 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 trial-installed a small batch for public sale. Unexpectedly, it was suddenly popular. Ordered 50 units. 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 was called "Apple Type I” (Apple I). This is the origin of Apple Computer. Later, Apple-type microcomputers quickly became popular all over the world, and the Apple Microcomputer Company, headed by Job and Wozniak, developed into an international enterprise with more than 4,000 people and established many branches around the world. There are almost no computers today that are not equipped with a mouse. Without this cute little 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", which is also called this in the invention patent. It was invented by Engelbart, a scientist at the Stanford Research Institute in the United States, in 1963. However, the most primitive mouse was made of wood and a small iron wheel, but the basic principles it was based on did not change much. The initial idea of ??inventing this device was to enable the computer to communicate well with peripherals. Better display, guidance and input of information. According to Engelbart's later recollections, around February 1951, at the age of 26, he had just retired from the Navy and suddenly became interested in computers. He thought, how to exchange information with computers better and more conveniently? And he was excited by the idea. In 1963, after 12 years of exploration at Stanford Research Institute, he finally invented this device. In the 1970s, Xerox continued to improve the mouse, making it what it is now, with more complete functions. In 1983, Apple Computer's personal computer was first equipped with a mouse.
Almost no one uses the name "Display system vertical and horizontal position indicators". "Mouse" is a popular and vivid name, but it has always been used. It was taken by one of Engelbart's colleagues at the Stanford Research Institute.
How is it? Do you like computers more now? Do you find computers more attractive? Then go online and have fun!
