Magic "Angel"-Computer

A computer is a magical guy, it can help people do many things, and it is also very efficient! It is an assistant given by God. With computers, we can do a lot of things! It can help us to look up information, and we can also ask it to be an "angel" if we don't know in our study. The computer is always with us, and it is silently 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. It is such an "angel"! ~

Let's talk about myself first. Before I touched the computer, I was like a headless fly who didn't know how to write words. Of course, I know that looking up a dictionary is a good way, but I just feel bored when I pick up the dictionary. Since I saw the computer, I can see many words by pinyin. I also learned from the computer that looking up a dictionary has many benefits, so I got used to looking up a dictionary! ~

Computers Many adults don't agree with their children to play, and there are only a few reasons. ① They are afraid of their children's poor eyesight. ② They are afraid that their children will not do their jobs and play with things (my mother is also afraid of me), but computers may not only bring disadvantages, but also have advantages, such as searching information, listening to music, watching news, setting up their own web pages, and being able to buy and sell things on the Internet without going out. It can also be delivered to your door.

I remember that in the summer vacation, I asked my mother if there were some English and proverbs that I couldn't do, but what I told her was-my mother couldn't do it either ... At this moment, my mother told me to turn on the computer to check ... I was only one year old at that time, and I didn't know how to find information and how to find the most correct information. My mother told me that you could go to Baidu, where everything was available. But at that time, I didn't know how to write Baidu's website, so I went to ask my sister. After asking, I knew that Baidu's website was:

www.baidu.com. After I knew it, I went to look for the information I wanted immediately. As my mother expected, I really found the right answer. I copied the answer right away. That day, I checked everything I didn't know, and I also checked what I didn't know. Now I know it. !

God gave us an "angel", that is, my "good friend" computer, and I am very grateful for the convenience it has brought us.

Computers

Computers have a close relationship with us now: we need computers to find information, play games, chat online and learn information ... In short, we can't do without computers.

Computers contain many contents, among which the Internet has spread all over the world. It is also called internet, and its original source is a military network of the US Department of Defense. When designing it, I didn't think of bringing the network to the whole world. I simply hoped that if a nuclear war broke out one day, a network could still spread all over the world after being attacked by a devastating attack, and it had the ability to quickly restore smooth flow. In 197s, the U.S. Department of Defense began to carry out DARPA project and set up 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, the data can still reach the destination by bypassing other countries. And 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 established NSFNET, which is responsible for global non-governmental network exchanges. This is the INTERNET in America. Although the U.S. government has many rights to the Internet, for the development of science and technology, the United States itself does not charge a lot of royalties for any behavior on the Internet (because the Internet is researched and developed by the U.S. government), so many research institutions can join the research and development of Internet technology and services at a very low cost, and the Internet has thus developed into the most extensive network in the world.

Apple and computer are two totally different things. What is the reason that connects Apple and computer? In the early 197s, micro-computer (microcomputer) came out, which attracted a large number of teenagers who loved electronic technology because of its complete functions and portability. There are two electronic fans who are only eighteen or nineteen years old in a small town called Kapatini near Silicon Valley, the computer base camp in California in the western United States. The older one is Steve Job, who helps to make a living in the apple orchard on the farm while studying at the university. The younger one is Steve Wozniak. He likes music and playing with all kinds of electronic instruments. He is also an amateur of electronic technology. The two are like-minded, and they have become a pair of close friends. In 1974, some local electronic amateurs spontaneously organized and set up a club to make microcomputers by themselves. Job and Wozniak joined in with great interest. They used an abandoned garage of Job's father as a studio and began to trial-produce microcomputers. They first try to assemble a microprocessor into a simple microcomputer, and then connect it with a TV set and a keyboard to form a microcomputer system. As long as the operator presses the key on the keyboard, the text and simple graphics will be displayed on the TV screen. This achievement was welcomed in the club, and then they tried to install a small number of them for public sale. Unexpectedly, they were ordered 5 sets at once. So, these two young people started a microcomputer company. To commemorate Job's work in the apple orchard during his work-study years, they named this new type of microcomputer "AppleⅡ", while 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, and Apple Microcomputer Company, headed by Job and Wozniak, developed into an international enterprise with more than 4, people and set up many branches all over the world. Nowadays, there are almost no computers without a mouse. Without the cute little mouse, a large number of various softwares can't be used well at all. So, how did the mouse come from?

The normal name of the mouse should be "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 at Stanford Research Institute. However, the most primitive mouse is made of wood and a small iron wheel, but the basic principle on which it is based has not changed much. The initial idea of inventing this device is to enable the computer to communicate with peripherals well and display, guide and input information better. According to Engelbarth's later memories, in February 1951, at the age of 26, he just retired from the navy and suddenly became interested in computers, so he thought, how to exchange information with computers better and more conveniently? And he is very excited about this idea. In 1963, at Stanford Research Institute, after 12 years of exploration, he finally invented this device. In the 197s, Xerox constantly improved the mouse, making it look like it now, with more perfect functions. In 1983, the personal computer of Apple Computer Company was first equipped with a mouse.

the name "vertical and horizontal position indicator of display system" is rarely used. The popular and vivid name "mouse" has always been used. It was taken by a colleague in Engelbarth, Stanford Research Institute.

how about it? Do you like computers better now? Do you think computers are more attractive? Then go online and have a good time!
