Chapter 3 2 Do you know about computers?

Before I get to the text, I have one more clarification.You must not expect to find a very clear picture in this book, so that you can fully understand what a computer is!Because this is impossible, not because the computer is too deep and complicated, but because it is too childish and simple.It is so naive that it can only do the most basic work, and it is so simple that it is just a combination of several institutions. Some people disagree and regard computers as gods, holding them high and unfathomable.The reason is that it is too simple and ordinary, and everyone can learn it and design it by themselves.Once you get the hang of it, you too can design a computer.Since it was designed by you, it is a secret to others, and it takes a lot of effort for others to understand how to use it.

To give a simple example, and assume that we do not have any knowledge of materials and structures, let us drift to a desert island.There are luxuriant trees and abundant fruits on the island, and fortunately we brought saws, hammers and other tools.At this time, to survive, you must first build some houses for living. I'm sure you have the ability, if necessary, and everyone has it.Some people like to be unconventional, some have unique insights and needs, some can adopt the strengths of other companies, and some blindly imitate. The house is made, and it is guaranteed that no one is exactly like another.Appearance, structure, portals, and compartments each have their own specifications and application methods, which are varied and even weird.

Well, if you haven't built a house yourself, or your family is too big to live by, why not buy a ready-made house?So, you start touring those houses.If the builder happens to be by the side and explains it to you one by one, maybe you won't be too confused.In case the landlord went to the beach to hunt for beauty at that time, or else he wanted to make a fortune and was busy rushing to build.If you can't find him for a while, it is very likely that you will not be able to enter, or you may be blinded by the door.Once inside, be careful not to hit the branch with your head, or you will step into the hole with your foot.Don't forget, there are no electric lights on the island!Even in the daytime, the outside is brighter than the inside, so you can’t go blind if you don’t want to!

This is similar to the current actual situation, the real estate business is too hot.Everyone is so busy that no computer company can send someone to accompany you to the end.Unless you're already a client, that's not the case because you're already in the suite.For someone who is just visiting, who knows if you are an industrial spy?Who wants to waste that time? It's easy to get to know one house, and something new is added in the second.Maybe someone hangs a big rock on the door of the room, and if you accidentally pull a rope, the rock will fall to the ground!That's anti-theft!Some people build toilets outside, which is hygienic but inconvenient; some people build toilets beside the gate, which is convenient but indecent;

It is not surprising that the houses we live in today have rules and regulations, which are the result of thousands of years of research and improvement by experts.So no matter what kind of house, door to door, household to household, the number of rooms and halls is clear at a glance.However, if you have the opportunity to visit the ancient and modern Chinese and foreign housing exhibitions, you will find that the concept of portals is not so uniform, let alone others. This is exactly the case with computers. Although it has helped humans land on the moon today, it is not how great it is, but how cleverly people use it.Everyone calls it cutting-edge technology, but it is just because it has just been born.Any new thing is easier to be favored, (of course it is also easy to be excluded, at least the embarrassing period of the computer is over.) What's more, it came into being as the times require.Just at this time when the population is exploding and human beings are already in a hurry, there is a guy who will do the work for them.Who said no?

However, if we look at today's computers in a hundred years, then the examples given above cannot be more appropriate.At least until that day, computers will have a principle to follow, just like our houses today. Take the United States as an example, there are thousands of computer companies, large and small.As for computers, there are more than a hundred kinds of well-known ones in the market. The backing garage products (don't underestimate the garage products, the Apple computer, which now ranks first in the home computer market, was made in the garage and sold in the store) are countless.

So many different types of computers are built with several basic materials and tools (we will introduce these materials one by one later).There is no definite rule, no unchanging organization, each shows its own magical powers, and each has its own victories.At this time, you must wonder why there seems to be no difference in what you see?Am I trying to lie to you? Of course, this is due to differences of views.Take a house, for example, no matter how strange it is, it must look like a house.The same goes for a computer, that look is part of what you think it looks like.Also, there is one more thing you might not know.In China, our vision is limited, and the commercial products introduced by various manufacturers have been objectively selected.I believe that you can name no more than forty brands, and those computers that are so weird that you think they don’t look like computers have already been struck out.

Secondly, when you enter the house and want to go in and play, you have to be careful.Even if you already have a good understanding of computers, or even a professional computer practitioner, when you come across a new product, you must first respect ghosts and gods and stay away.If you don't ask the doorway in advance and follow the customs when you enter the country, you may capsize in the gutter.Just because the ideas are different and the design methods are different, why set the entrance next to the kitchen?Why put a patio in a bedroom?No reason!Designers love this tune! There are many ways to use a computer. Some can be used immediately after booting; some need to remove the operating system first;At present, there are more than ten kinds of operating systems that are widely popular, and each has many well-intentioned revisions.Among the high-level programming languages ​​that are recognized as general-purpose, there are many kinds of high-level programming languages, and each of them has many different functional capacities.

Don't mention it, if you know the computers of the same brand and the generations, you may be too scared to use the computer!This is the truth, just because computers are still young, not mature yet, easy to learn and understand, everyone can play a role.In this world, technology has been upgraded from the ten-year generation 20 years ago to the three-year generation so far.It means that the technology you have learned can only be used for three years at present. If you don't continue to learn, you will fall behind when new things come out. There are advantages and disadvantages to the speed of technological update; the good side is that you need to work hard, and it is not difficult to catch up with the times, but the bad side is that it violates the laws of economics.What do you do when one system is not fully functional and a new one comes out?There is also talent and teaching. After ten years of hard work, I have achieved success through hard work, and the doctor's cap is still hot on my head. My stomach full of economics has become a thing of the past. (Fortunately, there is no such unnatural phenomenon in our country. Our doctorate has been a lifetime post since Emperor Wu of the Han Dynasty established it.)

Foreigners work hard, no matter movie stars, athletes, industrial and commercial practitioners, scholars and experts, no one wants to hold a golden job for a lifetime.If you want to survive, you need to make progress, and if you want to make progress, you need to keep learning and make breakthroughs. Approval is one thing, reality is another. Don't you want to understand computers?Why bother?Forget playing with electric toys! It is said that an American sociologist, in order to understand the behavior and mentality of primitive humans, specially selected a most backward nation for research.Let’s assume that this area is in Africa. He learns their language, eats their food, and lives in their cave dwellings in order to blend into their social circle.

This old beauty found it strange when he first learned the language. The old Feis called him Stupid God without calling him by his first name.The boundaries between each other gradually disappeared, Lao Mei seized an opportunity, and the chieftain poured a few bowls of John to walk, and the chatterbox opened. Stupid God!You have everything but no brains!The chief enthusiastically enlightened the old beauty. Lao Mei thought to herself, maybe she will gain a lot today, and learn from this ancient wisdom.Then please tell me, Lord Chief! Seeing that there was no one around, the chief winked at Lao Mei quietly, and then, holding a torch, he went into a small secret tunnel.When Lao Mei saw it, she was really dumbfounded, she couldn't even dream of it! Inside, there is a plastic mannequin missing a right arm, a 12-inch color TV, an electric fan, jeans, various western clothes, several bottles of Coke, and a plaster Statue of Liberty. Black oiled Marilyn Monroe poster! Lao Mei was stunned, he couldn't express his feelings.After a long while, the chief inspected for a week, and said triumphantly: Look, what you have, we have! Lao Mei really doesn't understand this mystery: what use are you for these things? Of course it works!We usually pretend to be stupid in front of you, but in fact, I often call my people here to teach them what to do. Lao Mei saw a few boxes of chewing gum and chocolates at a glance. They were originally used for teething festivals for some skinny little guys, and now they have also become demonstration equipment! I still do not get it!You really want to accept modern civilization is a good thing, why not do it yourself? So we call you stupid gods!The chief couldn't help laughing: It is because you think we are backward that you are willing to give us the things you have worked so hard to make. If we can do it, will you still give it away? A while ago, I saw a news report published in European newspapers: The economic growth of the Republic of China has leapt to the top of the backward countries.I don't know how you feel?We can't deny this iron fact, but thinking of the backward story above, it's like a needle piercing my heart! Back to shore!A lot has been said before, and the conclusion is only a few words.Everyone, don't think that there is a complete and clear computer image!Because in fact, the computer at present is just a combination of multiple technologies.Everything is just beginning today, and it will change tomorrow and the day after tomorrow.I can't harm you, let you have an unbreakable prejudice, this prejudice will limit your research and development, and make you think that you understand computers and are superior to others! Thousands and thousands, thousands and thousands, don't be satisfied with what you already know.Because I don't know how many new concepts are being formed and spreading, and I don't know how many deeply rooted and long-standing concepts will be overthrown.The whole world is progressing crazily, if you don't make progress, you will fall behind, and what is behind will disappear in smoke one day. Therefore, in this book, I can only tell you some concepts, and I am limited to the concepts that I understand.I know very little, and I can express even less.Now there are many reference books in the market, and they used to be my first teacher. If you want to learn more, don't be reluctant to buy one!
