With the development of technology, computers have entered the lives of many people. Last year, I also got a computer, which brought me a lot of convenience, increased my knowledge and broadened my horizons. Computers are divided into three main parts, the monitor, the main unit, and the keyboard.

A monitor is a large screen that, like a television, displays a variety of icons. The host computer is the "heart" of the computer, with two eyes, one large and one small, one to start the program and the other to restart the program. The biggest credit is the keyboard, which contains 26 English letters, 4 arrow keys, 10 numbers, and some indispensable function keys.

Each of them stays at his post and serves his master. The computer also has a small tail, which is the mouse, which is used to issue instructions, and the monitor will follow its instructions, which is the magical function of the computer.

Computers, also known as electronic computers, were invented by scientists after years of research. Electronic computers have been "multiplied" for several generations to become "versatile" computers. The computer can access the Internet, and the content on the Internet is even more colorful.

Don't look at the computer's hard body, if you encounter its nemesis, an electronic virus, the consequences will be unimaginable. However, you can turn on 360 antivirus and the virus can be destroyed, just like giving medicine to a patient.

At present, technology is developing at a rapid pace, and I firmly believe that computers will be one in the next few years.

In the 40s of the 20th century, IBM began to manufacture computers, and the era of computing came. However, computers at that time did not abandon the punched cards similar to those found on Jacquard machines, and were still programming with them. This continued until the late 80s of the 20th century, when punched cards were finally replaced by electronic media - tapes and optical discs.

At this point, we may be able to say that a computer is nothing more than an extremely advanced loom. What an amazing thing it is that the computer that we now think of as cutting-edge technology is connected to the loom. When you're using a computer, you're essentially weaving at the speed of light. ok

Computer's readme.

I'm made up of the display, the console, the keyboard, the speaker, and the mouse. My display is silvery-white, the main unit is a light blue cuboid, the keyboard is made up of 107 keys, and the mouse is particularly nimble like a mouse. My ancestor was born in 1946 with the birth of "Eniak", and I developed a new type of computer after four generations.

Some of my good friends look the same as me, some don't look the same as me, but the equipment in our bodies is the same! I have a motherboard inside my console that supports my work! The CPU is the processing center and it can handle my work.

I am inseparable from them. You can use me to write: if you want to write an essay, you can type and write on the keyboard, which is much more convenient than writing by hand, and typing will add a lot of joy to people.

I'm a new writing tool, and I know how good it is: fast; Easy to modify, easy to store, print and send; Writing with me is like playing a game console, and it's a lot of fun! If you're done, you can also publish it online and ask others to suggest revisions.

Networking is another big feature for me, and that's what I'm going to talk about next.

If you connect me to the global information superhighway, I will receive information from all over the world. Once you can play it, you will be able to look up information on the Internet. No matter what you use me to search, just type the name of the information you are looking up on the search bar, and you can search for the content of the information you are looking for.

With me, it's so easy! I also have many functions: drawing, playing games, watching TV, listening to songs, listening to radio ......These functions all have the same characteristics, which is convenience and speed.

I firmly believe that the new technology of science will be created and updated into my brothers and sisters' computers. My brothers and sisters and I will also become people's "companions", inseparable from people, and make greater contributions to mankind!

"There are two boxes square, and the little mouse is lying next to it. Touching and dotting every day, Bill Gates is happy. "Do you know who I am? By the way, I'm the computer everyone is familiar with.

In today's rapid development of human electronic technology, our family, as a leader, has climbed to the top of today's electrical pyramid after countless reforms, innovations, upgrades, and optimizations, relying on amazing memory, fast calculation, and keen judgment.

When the scenery is infinite, I will think of the first family, the first computer. Born on February 15, 1946 at the University of Pennsylvania in the United States, it uses 17,468 vacuum tubes, consumes 174 kilowatts of electricity, covers an area of 170 square meters, weighs 30 tons, and can perform 5,000 addition operations per second.

We have gone through four generations, including vacuum tube manufacturing, transistor manufacturing, integrated circuit manufacturing, and manufacturing using ultra-large integrated circuits. Since then, it has been continuously updated in the direction of miniaturization, miniaturization, low power consumption, intelligence and systematization. In the 90s of the 20th century, we could think, learn, remember, network communication, etc.

After 2000, we are notebook, miniaturized and specialized, with a speed of more than 1 million times per second, which is not only easy to operate and cheap, but also can replace part of people's mental work, and even expand people's intelligence in some aspects.

Are you ashamed of my family tree? If you still want to compete for my throne, then look at my strength.

My brother and I have joined forces to create virtual worlds that provide convenient and efficient services to humans and make them obsessed with and dependent on us. We manipulate humans to upgrade and update us, and it seems that they manipulate us, but in fact we control the world.

What do you think? Scared? Nowadays, our undercover agents have infiltrated the human world in large numbers, and we have to slowly destroy their bodies, so that their eyesight declines, cervical and lumbar intervertebral disc herniation; Let them sink into the swamp of entertainment games and never turn over.

Their brains are starting to get dull and unresponsive.

Haha, these poor human beings, who don't even know it, are still willingly manipulated by us!

When our computer family dominates the world and reigns supreme, it will be the beginning of the end of your human race.

After listening to my introduction above, do you have a new understanding of me?

Humans, work hard for our computers!

I'm a computer, my brother is a lot, laptops, desktops, laptops... And I'm a laptop.

My family is very large, our ancestors can weigh more than 2,000 kilograms, with the rapid development of mankind, we continue to **, until people can hold us in their hands.

We have the knowledge to answer all your questions, of course'Thanks to humans having a smart brain.

Do you like me.
