Chapter 428

"You said..." the old man gritted his teeth.

"For example, in the top two of the class, the first one got 100 points and the second one got 99 points. It seems that the gap between them is only one point. As long as the second one checks carefully during the exam, he can be tied with the first one. However, no one has thought about another problem. If the full score is not 100, but 150 or more, the one who depends on 100 will probably get 150 or more. But the second one, who scored 99 in the exam, may only reach 123 10 by then. "

Liu Lang said faintly: "similarly, this is also the difference between the constitution which is infinitely close to the body of nine Yin and the real body of nine Yin. The body of nine Yin is the first place in the test of one hundred points, and the constitution infinitely close to the body of nine Yin is the second place in the test of ninety-nine points. In this way, do you think it's more intuitive? "

"Lying trough..."

Bad old man is a rude burst out again, "still his mother can be like this?"

"So, old man, brain is a good thing. I hope you have it, too." Liu Lang laughs.

"Get the hell out of here and die." The old man is very upset now and doesn't want to pay attention to Liu Lang.

And he didn't care, because at the moment, Liang Zixin had already taken them outside the "spy hall.". Bad old man can't follow him because he can't show up. After all, there are many people in the room. Even if he is confident that he won't let those people find his trace, the world is not complete. If he is found, it will be over.

Detective hall, the name is reminiscent of the intelligence department in ancient times. Inside, there are all kinds of wooden mechanisms, wooden gears, cloth strips connected to the shaft, creaking rotation.

There is also the unique smell of printing press and rice paper.

However, when they really went in, they found that the scene inside was totally different from what they had imagined. It was just a sky and a ground.

But when I think about it, I feel relieved.

After all, what age is it now? How can we use the things of the last century?

Not to mention the quality problem, whether the long-term operation can be maintained depends on the efficiency problem, which will result in a big cut down, and the gain is not worth the loss.

In the spy Hall of Emei school, all computers are placed. As soon as I went in, I heard all kinds of printers, copiers, the sound of paper in and out.

Everyone is busy, some sitting in front of the computer, hands constantly dancing on the keyboard. Some operate in front of printers and copiers. After printing or copying, some collect documents, put them into files, and put them into a large bookshelf similar to books and materials in a library.

"Now that we all have computers, we can store all kinds of data, and it's very convenient to access them. Why do we have to do so much to create such a large pile of files?" Seeing this scene, Hongling couldn't help wondering.

"Little sister, you don't understand, because the computer is not safe." Liang Zixin saw that Hongling was very cute. When she asked this kind of question, she immediately said with a smile.

"Who do you call younger sister? I'm much older than you." Hongling squinted.

When the bad old man is away, her "true self" posture appears again. Everyone calls her "little sister" and calls herself "big sister" in front of her. Hearing that, Hongling is really crazy and wants to do it.

However, her accomplishments were sealed by the bad old man. Now she has no strength at all. She is just an ordinary 10-year-old girl.

Of course, it's just the appearance that makes her angry.

It's not that she is called "little sister" that makes her angry. Hongling doesn't think it's any good. She is angry with Lao Zao, but she is afraid of Lao Zao's strength. She is angry with her attitude and shows weakness. How can she accept it.

All kinds of complicated emotions, for a moment, made Hongling confused. Her mind was in a mess, so she became more and more agitated. Her anger naturally ran upward, and her breath was as high as three feet. She couldn't even control herself.

"... you're very interesting, little sister." The expression on Liang Zixin's face suddenly stagnated, then he gave a dry smile and said.

"If you want to find the information of the outside world, you have to access the network. Once you access the network, it can't be one-way. You can find the things of the outside world, and the people of the outside world can naturally invade you. Therefore, the most important function of computer is to investigate information, not to store it. It is not safe. " Liu Lang explained.

"If one group of computers are connected to the Internet, and another group of computers are not connected to the Internet, it will be much easier and faster to retrieve information, won't it?" Hongling thought and said."It's reasonable for you to say that, but I believe there must be a number of computers in the spy Hall of Emei that are not connected to the Internet, right?" Liu Lang said with a smile, then turned his eyes to Liang Zixin and asked faintly.

"Well, that's right. We do have a number of computers in our spy hall to store information and to facilitate emergency inquiry. These computers are not connected to the network Liang Zixin nodded.

"If so, the question goes back to the beginning. Why waste so much space to store these files?" Hongling Road.

"It's very simple. Zixin answered you just now. Because of the computer, it's not safe." Liu Lang took a look at Liang Zixin and then explained to Hongling, "these electronic products all have one thing in common, that is, they all need power supply before they can be used. In places like Mount Emei, where the voltage is unstable for a long time, these computers can't be used normally for a long time. Of course, there are generators... Well, this kind of thing is a little noisy, which affects the quiet environment of the Emei school. In addition, the stored data are all data. If the voltage is not stable, it is very likely to be lost. Therefore, physical data backup is needed. "

"You... How do you know Emei so well?" Liang Zixin looked at Liu Lang in surprise, wondering who this guy was and how he felt that the Emei sect didn't exist in his eyes.

"Not only that, I also know that some important data will be specially placed in some places, and will not be stored in those computers without Internet connection at all, because there is also the technology of data recovery. Liang Zixin, Daoyou, you said... Am I right?" Liu Lang stares at Liang Zixin with a smile and says
