A few months ago, Liu Lang told Shao Mingtao and Sun Desheng his views on the building of the national armed forces, and the core of it is to speed up the building of informationization, and also "predicted" that the Americans have initially realized the informationization of the armed forces, at least in the area of information systems.

At that time, Liu Lang also predicted that Iraq and Kuwait would fight, but now his prophecy has come true, of course, this prediction can be thought of by many people, after all, the two countries have been in conflict for the past two years, and Liu Lang also predicted that the United States will send troops, and will completely defeat Iraq in just two or three months, almost perfect victory in this war.

This point of view was unacceptable to Shao Mingtao and Sun Desheng, and even if Liu Lang explained the power of informatization, they could not imagine what role this power would play in the war, and this view also reached the ears of the top leaders.

Liu Lang's cognitive ability is naturally incomparable to others, which everyone admits that he has put forward many valuable but valuable views on the construction of the country.

However, the idea of applying information technology to the military seems to be somewhat inconsistent with the reality of the moment, and not many people are able to put it into practice, because after all, there is nothing intuitive, and even the state feels that the computer industry is the most important component of information construction, and it is enough to do this well.

Therefore, at that time, not many people paid enough attention to Liu Lang's proposition, and felt that it was good to do it step by step, and there was no need to be too anxious, until the book "Digital Survival" appeared.

In this book, Liu Lang elaborated on how informatization is applied in all walks of life, and especially devotes a chapter to describe how war is carried out in the information age.

Bai Weiren likes this book very much, and has specially asked some scientists and generals to discuss the technology inside, most of them agree with Liu Lang's description of the information world, but it is difficult to say when it will be realized, the most optimistic think it will take thirty or forty years, and the conservative estimate will be fifty or sixty years, but in fact, seventy percent of the content of this book has been realized after twenty years.

Bai Weiren is not sure when the information age will come, maybe thirty or forty years from now, but why not do it now? Of course not, since information technology will change the times, then the country cannot be left behind.

It happened that Liu Lang put forward the idea of building a campus LAN in the university at this time, and Bai Weiren had of course agreed to this proposition, and he was relieved to hand over this matter to Liu Lang.

Liu Lang spent more than 20 minutes to introduce everyone to what informatization, and most people understood it, which still relied on Liu Lang's super expression skills.

"Liu Lang, you said that you want to build a LAN on campus, then you can talk about how to implement it!"

Bai Weiren then asked.

"A LAN seems simple, in fact, there is a very complex technology behind it, first of all, there must be a terminal, that is, a computer, this is the simplest, but the structure of the computer has to be transformed, to add a LAN access system.

The terminal is simpler, the most important is the transmission medium system, for example, we call to convert the sound signal into an electrical signal, and then transmit the signal through the telephone line and the switch, the LAN transmits the digital signal, this signal can not use the traditional line and switch, the need to use optical fiber and the so-called server.

Everyone should have heard of optical fiber, our country can manufacture it, but the server is very difficult, involving a lot of technical difficulties, this is a system engineering, not a certain enterprise and department can complete independently. ”

After Liu Lang finished speaking, Bai Weiren nodded slightly.

"By the way, Liu Lang, you mentioned a Guowei company before, saying that this company has a certain technology, how are they?"

"Very good, the person in charge of Guowei Company is called Ren Weitian, a college student in our country in the sixties, who studied communication, and has a strong professional level, in addition, this person has seen the technology of the Americans, knows where our gap is, and more importantly, I have seen the quality of Zhou Lao, Huang Lao, and Xiong Lao's generation in him, so I choose to believe him. ”

Hearing Liu Lang comment on Ren Weitian like this, Bai Weiren's heart moved, he knew Liu Lang very well, don't look at his young age, but he has great respect for the older generation, and he also takes these seniors as an example, he evaluates Ren Weitian with his own example, which is obviously a very high standard, which is rare.

"Liu Lang, you have a high opinion of this Ren Weitian! But after all, he is a private enterprise with few resources, so why can't SMIC do such an important project?"

In Bai Weiren's eyes, SMIC has the best semiconductor technology in China, and they should take the lead in this matter.

"There are many types of chips, SMIC's terminal chips, just in terms of technology is more complex, Ren Weitian is a base station chip, the complexity is poor, but the base station chip at this stage uses the American framework, any chip of this kind of framework needs to be authorized by the United States, if it is a private enterprise in terms of authorization, it is relatively easy.

Each chip needs to spend a lot of manpower and material resources, but also to constantly update, SMIC's terminal chips are now very difficult, if you take out some energy to engage in base station chips is undoubtedly asking for hardship, so I suggest that Ren Weitian do this. ”

Liu Lang directly stated that he wanted to support Ren Weitian.

"Haha, you are very confident in Guowei Company, but you just said that SMIC is struggling to make computer chips, I don't agree with SMIC's profit last year, but it was 4 million US dollars, and 12,000 chips were sold, which is still difficult?"

Bai Weiren said with a smile.

"Last year, more than 500,000 computers were sold in the United States, and VIE alone sold nearly 200,000 units, and the chips provided by SMIC were less than one-tenth of VIE, and the sales volume of computers in the whole world developed at a rate of 15 percent every year, but SMIC's sales volume only increased by 10 percent every year.

In fact, most of VIE's chips are provided by TSMC in Wanwan, and their technology is already stronger than ours.

As a result, SMIC's technology is no longer the world's leading. ”

What Liu Lang has to say, he will not hide the objective facts.

The scene was silent, many people have always thought that SMIC's technology is already the world's leading, and today I heard Liu Lang say this before I knew that it was not the case.

"What .........?"

Bai Weiren was also taken aback, he thought the same as others, he always felt that SMIC's technology was at the first-class level, but it was not the case in Liu Lang's mouth, he didn't believe it, but the sales volume would not deceive people, Liu Lang said several data objectively showed the facts, and it was impossible to refute it at all.
