Chapter 9 8 Can we ignore Chinese computers?

It will be difficult to turn back when talking about those technical issues, and look at the other side of the computer!We already know that the computer has a main system to do miscellaneous tasks such as storage, printing, and delivery, and the main system is controlled by the keyboard to execute the input data according to human requirements. I also talked about the general operating system earlier. If the operating system is not competent for something, we have to write some programs to replace the operating system so that it can work for us. Now we're going to talk about: how do computers work for us? , there is an example that is easy to understand. I wonder if you have seen the living room factory?The goods entered the gate and were sent to the living room, where the whole family was busy working.The finished semi-finished products are put on one side first, and there are too many, so they are carried in and piled up in the bedroom.Wait until the semi-finished products can be combined, then take out the piles in the bedroom, and then process them until they are completely finished, then pack them up and wait for shipment.

The door can be regarded as a keyboard, which is the import and export of delivery and data.The living room is the operating space, the larger the space, the more goods and work that can be accommodated.Generally, the plot unit of the living room is ping, while the unit of computer computing operation space is called thousand strokes, which is 1024 bits.Generally, the size of the living room is ten ping, and the operating space of the computer is 64 thousand strokes as the standard. In the living room, some tools must be placed for production. There should not be too many tools. If they are too full, there will be no place for the goods to be placed.Too little is inconvenient, and so is the computer.The operating system is the tools and staff, accounting for tens of thousands of positions.The writing program is also a production tool. Of course, the simpler the writing, the better.The bedroom can be used as a warehouse to store goods, and it is regarded as a peripheral device for storing data in the computer, and the door of the bedroom becomes the entrance and exit of the peripheral device (or warehouse).

Ok, it's time to start working.But we have to assume that the factory can only work with electricity, and that when the electricity goes out, the living room will be cleaned automatically. The first step is to turn on the power of the computer. At this time, the living room is empty.We have to move the operating system to the disks of the workers (there are also workers who are always placed in the living room, etc., but if you think about it, you can understand that unless you specialize in certain tasks, the space will be wasted.).At this time, as long as you press the designated key, you will be ready immediately.

Now the user must input what he is going to do, for example, to register the daily journal.This is not a normal operation but a specially written program, so I type in the name of the program and the operating system starts to check whether there is this batch of goods in the inventory.Of course there is no way to do it, the operating system will give you a question mark, and then wait for instructions.If there is, these workers are busy carrying.Because the doors are small, the entrances and exits are often congested with traffic, so it takes a long time for everything to pass through the entrances and exits.

Goods are in place and new ones are coming in.The classification of the classification, and the separate processing of the processing that needs to be processed.For the daily account, it is the names and numbers that the user can see through the monitor and use the keyboard to command and dispatch.What should be added, what should be subtracted, everything has been done, and then it will be taken back to the warehouse for later use. So when you want to buy a computer, know how much work you have to do?How much space will these jobs take up?A large living room is good, but too little work is also a waste.As for a lot of work, the living room is too small, so we have to move out of the warehouse bit by bit to do it.Do a little, tidy up a little, but you may have a headache.

In addition, the tools used are also very important, whether there is ready-made software for use.If not, how easy is it to write?This is why there are commercial, domestic and private use in microcomputers.It must be above 64K for commercial use, 32K for home use, and 16K for private use.In addition to the size of the space, there are also differences in capabilities. Commercial operating systems are professional players.Some can work in different shifts. One system can provide several living rooms and factories (mostly four groups), while the functions for home and private use are limited and the cost is relatively low. It is more suitable for learning and small amount of data processing.

In the field of commercial microcomputers and minicomputers, if there is no off-the-shelf software program to use, it must be done by experts.Some computer companies do not provide this service, but through so-called software companies. First of all, what you come into contact with are system analysts. They need to fully understand what do you want the computer to do for you?how to do itAfter they fully understand, write the plan and process, get your consent, and then write it into a detailed flow chart (the so-called process is the process of handling the procedures one by one).Then hand it over to the programmer to write the program.Usually a small program takes several weeks to write.

The most common form of this type of program is: the first part is the procedure and method of creating a file, and building a file is to input data in a certain format.The second part is to search and modify files or clear files, you can use it to find information, modify and change.The third part does various processing, such as printing reports, calculation, sorting and intersection.This form is not necessary, but it is a method that is easy to understand and apply.After the program is written, it needs to go through the work of debugging. This procedure is often the most troublesome. Even the best programmers will inevitably make mistakes. It takes real skills to know where the mistakes are. We usually refer to debugging as catching bugs. , All moths must be caught before it can be handed over to the user for trial use.

Looks like a lot of trouble, doesn't it?But if you know the price of its work, you will know that it is absolutely worth it. We often hear people mention the word human nature, especially those who have read some philosophy books.In fact, it is not necessarily philosophers who understand people best. What philosophers discuss are precise concepts. We only need to know the facts.The fact is: human nature is the common problem and common feature of you and me. When you think about yourself and look at others, your human nature will be revealed. The common problem of human nature is that we are afraid of trouble, easily bored with unchanging things, it is difficult to focus on a single thing all the time, and we are often affected by physiology and psychology and become restless.I am so, and you are no exception.

If you think about it again, how many things in our lives are colorful?How many things can make you enthusiastic and unremitting?How long can it last?If you are only a middle school student, I am afraid I am not right to say this, it is too easy for you to agree with me.Because you're insane in pain doing your homework, and you're yelling because your mom made you take a shower!Not to mention letting the computer take a bath for you, it is not a good idea to let the computer study for you, it will never return it to you. However, it is also a good idea to use a computer to practice homework, because every question must be answered, especially the computer will not be like brothers and sisters, and the face will be ugly when asked for the third time.The computer can also test you and compete with you. As long as you are not tired, it will accompany you to the end.

The modern general industrial and commercial circles, although they are busy every day, there are actually few new things.Either incoming materials or shipments, checking inventory, inventory, company transactions, personnel and salary, etc.And these things happen to be destined to be replaced by computers sooner or later. There are many factories in Japan that are empty. Every day, goods come in and out, and the machines are all automated.All kinds of instruments and tools cooperate with the control of the computer, working faithfully and diligently.At sea, a large oil tanker with a capacity of 300,000 tons can play football on the deck, but only one captain and a few technical engineers are enough. What about people?I heard that everyone went to Tokyo to be crowded. (You will wonder why I only mention Japan. The United States is the first country to develop fully automatic technology. But the United States emphasizes democracy too much, and the trade unions strongly oppose automation, because it will take away workers' jobs, so it is cheaper for the Japanese.) Talking about these is boring, I might as well skip the present day that you can see with your eyes, and let you travel to the future world.I also want to tell you the real potential of the computer, don't think I'm bragging, this cow is waiting for you to bring it to us! Xiaodi Wang lives in underground city No. 14056 with his parents. His father, Mr. Wang, is a technician of the space solar microwave transfer center.In the past, 85% of the energy radiated by the sun to the earth escaped.Now through the collection of the space station, not only the escape has been reduced to 5%, but also the collection radius can be expanded.According to the five-year plan of the center, all the strong gamma rays that are 100 kilometers above the earth will be included in the energy supply of the earth. Mr. Wang's work in the center is relatively busy. He takes one shift every day, one hour each time.His task is to sit in the main control room of the computer, check various instruments occasionally, and see if the computers are too tired to affect the work mood. After the work is over, Mr. Wang only needs to press the oblique crystal oxygen on his wrist (note: a metal oxide semiconductor and a metal crystal with a 1.36-degree deviation of the main axis, which is used for signal control.) He immediately goes through space displacement and returns from space to 14506 Dungeon Home. Mrs. Wang is lying on a weightless chair, watching a TV interview program on the strike parade.In the middle of the living room, a metal frame is attached to the floor, wall and ceiling. One end is the family and friends reunion area, and the other end is the space-time interface area.If you want to go to the beach, it will become a beach; if you want to go to the mountains, it will bring the mountains to you.Where you want to go, it is there, the only thing it can't do is a place without space-time interface devices, or when you don't want others to break into your home. Mr. Wang stepped across the space-time interface, and Mrs. Wang immediately came up to him and said with a smile: You watch TV!Your union is going to win! Mr. Wang said: Impossible, I read the latest data on the computer today, and the sunspot activity this year is 2.3% higher than the forecast, and the energy harvest is poor! What does it matter?Everyone just took the opportunity to rest! rest?We go to work for one hour every day, and that's the break time.You see, you are sitting at home, using time-space conversion, roaming freely, and entertaining, and consume 0.45 joules per second (note: a new energy unit, a joule is a joule of solar energy). How much consumption will be increased for the 10 billion people in the world? snort!You!I'm afraid people don't know that you are working in the energy center. If you don't have enough energy at any time, you have a computer to figure out how to solve those things. Why do you worry?When Mrs. Wang is angry, she looks very cute. I wasn't worried at first.Mr. Wang pointed to the crowds of demonstrators in the space-time zone and said: Do you think they will win?That is a dream!All major issues in the world today are decided by the Earth Computer Union. Computers stipulate that each person works for one hour a day. It does not mean that computers need help from people. Don’t be pretentious. The value of people has long since ceased to exist. Computers support us Just embellish their lives.Mr. Wang couldn't help getting excited when he said: People really don't live up to their expectations. You must know that wisdom and knowledge can only be enriched with more use.There is only one hour left in a day and you don't cherish it. You live in the time-space interface during the day, and indulge in the dream machine at night. You fool around all day long. When will it be? Mrs. Wang couldn't take it any longer, she immediately asked: Last time you promised me to go through the procedure of longevity for my son, what happened? What are you in a hurry for?Mr. Wang became even more impatient: the computer authorities still want to investigate! My son has already agreed! His promise does not mean that he is willing, he has the right to grow up, how can he be a child all the time? (I have to explain that people at this time already have the technology of immortality. In order to maintain the fixed number of population, the computer stipulates that the reproduction of the population will be frozen at the beginning of the computer era, and only one person will be allowed to be born every time a person dies. It is human nature to have children. One, at this time, the most difficult desire for human beings to satisfy is the desire for children. Mrs. Wang is no exception. Since she is infertile, she hopes that her son will never grow up and will always be by her side.) Mrs. Wang knew it was because she was too selfish, but how could she not be selfish?She still has eternal, long, endless years stretching peacefully ahead.Everything in the new era is good, and there is nothing wrong with it, but computers don't understand human nature, and they can't solve human problems.There was a longing in her, the longing of every mother in the world.She wanted to embrace a limp, helpless little body with her life, say meaningless words, and make unreasonable faces. In fact, this is not difficult. The computer authority has prepared a complete set of programs especially for the mothers of the world.She can adopt a white doll, a fat doll, a black doll, a small doll, or a doll that looks exactly like herself at any time, and she can also return it to the computer authorities at any time.These dolls are of course not real, but no matter what angle you use to study and analyze them, they are no different from real dolls.When he is hungry, his little hands will scratch and cry, and when he is satisfied, he will babble and giggle to himself for a while, innocent thoughts will flash in his little eyes, he will defecate and pee, even the smelly smell The taste is also authentic. However, Mrs. Wang still seemed to be missing something, she couldn't say it, in short, she couldn't satisfy the primitive feeling that had been passed down for millions of years.Therefore, the only way to keep the son from growing up, Mr. Wang and Mrs. Wang quarreled countless times.Mr. Wang refused at first, but there was also a fierce battle between reason and emotion. Sometimes reason failed, and Mr. Wang agreed.As soon as reason raised his head, Mr. Wang regretted it again.This kind of matter is related to the happiness of the son's life, how can he make a hasty decision? When the two were about to start a big fight, the doorbell rang and Mr. Wang took the opportunity to step down.Press the Tilt Crystal Oxygen, and a picture will appear in the space-time interface. It is a cute six-year-old boy. He is sweating profusely in a children's playground, sucking ice dew juice in his mouth, and facing the space-time in the field. interface. When Mrs. Wang saw that it was her son, she immediately beamed with joy, and when she pushed the button, the screens of the two parties were connected. Son, come back and have a rest! When Wang Xiaodi saw his mother, he also happily said: "Mom!Come and play with me, okay?I found a puppy who can understand me! What's so fun about dogs?Dirty and smelly!Mrs. Wang is most afraid of small animals.Little brother Wang begged every day, and tried his best to bring pandas, miniature elephants, golden-backed turtles, glass snakes, and even raised a little white ape who could do housework, but Mrs. Wang's patience could not last three days. Mom, this kind of dog has been processed by computer, so it is absolutely not dirty or smelly, look!It also takes a bath by itself! Wang Xiaodi was performing his grinding skills again, he picked up a water basin on the ground, and then (suddenly) blew the whistle.In an instant, a long-haired puppy with indigo color jumped out from his wet lapel.The dog is only a little bigger than a human's palm, as if after rehearsal, it performed a fancy rollover very skillfully and confidently.Then, the puppy dived into the water, and the water splashed.The younger brother's head and face were covered with drops of water, and even Mrs. Wang was startled, and she couldn't help but hurriedly hid. The puppy seemed to know that it had caused trouble, so it immediately turned around, grabbed the edge of the basin, stretched out its little tongue, and licked Wang Xiaodi's face.Little brother Wang was itchy and sick, and he hid while laughing, and the water spilled all over the ground again. Stop messing around!Let the dog go!Mrs. Wang was angry. When the puppy heard this sound, it was so frightened that it quickly shrank back, pitifully huddled into a ball, and dared not move. Mom, please!Little brother Wang looked at the puppy, really reluctant to let go. No, you come back to me.Mrs. Wang will never forget the past when the glass snake got into the bed. Little brother Wang was crying in despair, and he still wanted to make the last effort: Dad.Sometimes Mr. Wang will stand by his side, and there is hope for war. Mr. Wang knows the significance of these small animals to his son. Although these are computer toys, as a playmate, they are far cuter than real small animals.The children of this generation are so lonely and completely isolated from nature, it can almost be said that they are raised in a modern prison! However, Mr. Wang has one more thing to consider. In this era, everything is not measured by money.But computer sensing devices have spread all over the world, and everyone's every move is under the surveillance of the computer, and every enjoyment comes at a price.Everyone's price has an exchange value, beyond which there is no chance of credit.Fortunately, as long as it is an individual, the basic value can maintain the right to life without additional enjoyment, and the additional enjoyment must be exchanged with one's own time. A puppy is an extra enjoyment in addition to the right to life. Mr. Wang has to figure out whether he can afford it, seeing the pitiful state of his son and the puppy.Mr. Wang's emotions overcame his reason again, and suddenly he had an idea, and said to Mrs. Wang: "It's fine if you want me to go through the formalities immediately. I have an exchange!" Mrs. Wang glanced at her husband in surprise, and asked cautiously: "What kind of conditions?" It's very simple, if you want your son to never grow up, you have to let him be satisfied with his environment, otherwise it's unfair. Mrs. Wang thought it was reasonable and nodded. As long as Mr. Wang didn't propose to buy a computer beauty to take home, any conditions are negotiable. Mr. Wang went on to say: Let him bring the puppy back to accompany him! When Mrs. Wang heard that raising a puppy annoyed her, it was not a problem to have a baby by her side forever.It was rare that her husband took the initiative, and she immediately replied happily: let alone a dog, a hippopotamus is also fine! Little brother Wang also burst into laughter, and immediately pressed a button, through the space-time interface, with water still dripping on his body, holding the barking puppy in the basin in his hand, he threw himself into the arms of his mother. Puppies are not necessarily annoying!Mrs. Wang thought to herself, she moved from the contented and joyful face of her son to the little guy with long blue hair, who also knew that he had a home, and desperately licked her fingers.Mrs. Wang also thought of her son sucking her fingers when he was a baby, and she couldn't help thinking wildly: I wonder if it would be good to have a child whose whole body is blue? . Seeing this happy scene, Mr. Wang felt warm in his heart. He took the opportunity to say to Wang Xiaodi: Son, you should know that since the computer era, your mother and I have grown older than our current age, only you Still growing year by year. Little brother Wang immediately went on to say: Dad!I know, my mother told me that I should also run Changqing. Yes.Mr. Wang said again: "This is a big event. You are still young. I'm afraid you don't understand it." I know.I want to be like this forever.The puppy struggled to jump to the ground, but Wang Xiaodi refused, and the puppy barked.Little brother Wang slapped it, and said to the dog: Don't make noise, listen to Dad! Regardless of whether little brother Wang can understand it or not, this matter must be carried out.The decision cannot be reversed in the future, because the computer authorities only give humans the right to choose once. The reason is very simple. In computer logic, there are only two situations: yes or no. Mr. Wang felt very sorry. He gritted his teeth and made up his mind that in the future he must make up for his son who will never grow up and satisfy all his demands. The procedures are very simple, he uses the button of the oblique crystal oxygen to connect to the computer Changqing Center.Immediately, a large office and a halfling man sitting behind a large desk appeared on the space-time interface. This man has a standard face and a standard voice, and is an interface for the computer authority to communicate with people. The computer person uses its eternal, rational voice to say: The applicant's information has been received, have you made a decision? Mr. Wang and his wife answered in unison: Yes. The computer man asked again: Brother Wang, how about you? Little brother Wang had never seen such a serious scene, so he was a little nervous because he was frightened, and he said in a low voice: Uncle Computer, I am willing! . Well, your testimony has been recorded and archived, little brother, come over here.said the computer guy. Little brother Wang glanced at his father and asked his mother in a low voice: Can I take the puppy with me? Mrs. Wang lovingly stroked her son's head and said: Of course. Little brother Wang hugged the puppy tightly and stepped into the space-time interface.In an instant, a beam of light shrouded Wang Xiaodi, and then, the big office and the computer people slowly faded away, leaving only a blessing: Congratulations, you are immortal! At this time, younger brother Wang was still in the other half of the living room. Mr. Wang and Mrs. Wang hurried over, hugging the bewildered son tightly.Mr. Wang was full of guilt and said: Son, I'm sorry, tell me, what do you want, no matter what it is, my mother and I promise you! real?Little brother Wang didn't quite believe it. real!child!Mrs. Wang also spoke sincerely. Little brother Wang thought for a while, and said longingly: I hope to grow up soon and be an engineer like my father.
