Super Weapon Swap System

In that parallel time and space, the Internet originated from Eagle country. Eagle people are in an absolute advantage on the Internet by virtue of their position.

For example, this root domain name server is all controlled by Eagle people. As long as you control this server, you will control the Internet all over the world. For other countries, the threat is great.

They can paralyze the world's networks at any time.

After all, it seems that if the simplest standard domain name to be accessed is to be resolved into an IP address, according to the technical process, it must go through the work of the global "hierarchical" domain name resolution system, that is, the root server, which manages the domain name information of countries around the world. Below the root server is the top-level domain name server, that is, the database of relevant national domain name management institutions, Level by level query, and finally realize this transformation.

In the actual process, it is impossible to fly to Eagle country. Most of them implement caching locally. However, in the most direct theory, this is still possible.

So why not build such a root domain server in your own country?

This is because the number is limited. This DNS protocol uses UDP and TCP protocols on the port, and the maximum length that can ensure normal operation in UDP query and response is 512 bytes. In this way, in order to make all root server data contained in a 512 byte UDP packet, IPv4 root servers can only be limited to 13.

The total number is only 13. Of course, there can only be 13 when the global Internet realizes interoperability.

Unless China only uses the Internet at home and does not contact the world, it will be absolutely closed to the outside world. This will lead to backwardness at home. Our own side will not do this.

It's only in the 1980s, when the Internet has just sprung up, our own Internet has begun to move forward in great strides. In this way, we can make other countries close to our own side. At least there should be three or five root domain name servers in China, so as not to be controlled by others. With Qin Guan's explanation, Ni Gong immediately understood: "President Qin, rest assured that this belongs to the strategic security on the network, and we will deploy it in place."

In later generations, this defect was not supplemented until the IPv6 network. Han has its own root domain name server. There is no need to worry about this problem. Once the root domain name server has a problem, it will lead to national network disconnection at any time. For some network companies, the loss of one hour of network disconnection is huge. For the whole country, All walks of life have been linked to the network. Once the network is disconnected, no one can afford it. This is the best way to hit a country's economy.

After Qin Guan deployed this matter, he felt that he had completed his mission in Huating and could go back at any time. At this time, Lisa summoned Qin Guan again.

Steve Jobs, you've cleared the customs!

When he heard the news, Qin Guan raised his arm and looked at his watch. How long did it take?

The fastest record will take hours, won't it? Has jobs played before? It's impossible. This game only exists on my computer. I take it out and play it from time to time.

Even if you don't look at the strategy or the beautiful words, you just go straight into the game and come out of the maze at one time. It's impossible to complete it now. Does jobs have the talent to play the game, or did he find some unknown back doors of the game?

When Qin Guan walked back, he was full of laughter and tears. This is the first segment. He hasn't started his trip to Suzhou yet. Is this even customs clearance?

Have you ever played games?

"President Qin, I've thought of what I'm going to do." jobs obviously didn't stick to the specific plot of these games with Qin Guan. In the process of just playing the games, his brain was also thinking about the conditions put forward by Qin Guan.

When it comes to software, he really doesn't have that idea. He just likes hardware. After all, he came from hardware at the beginning.

However, Qin Guan gave him restrictions again. Very simply, he could not cross the border and threaten the survival of Hanxin technology company. Under these rules, he was almost impossible to develop.

However, just when he was playing the game, he finally found an idea, which immediately opened his mind and could continue his career.

"What do you want to do?" Lisa asked. As a manager of a large company, Lisa is not surprised, but now Lisa is really worried. It seems to be a trial for her. Once jobs wants to make up his mind to do something, almost nothing can change him.

They haven't married yet. People like jobs won't get married easily. He is a paranoid technical talent.

"I want to make a game console," Jobs said.

recreational machines?

"Nintendo's game console is too backward. I want to use our hardware to create a cross era game console. This is my field," Jobs said.

Jobs has identified himself. If he wants to continue playing hardware, he can't conflict with Hanshin technology. Then, you build your personal computer and I build my own game console!

Game consoles have similarities and differences with computers.

Both are based on the principle of computer, CPU, memory and so on. It can even be said that the computer can almost perfectly play the game of game console, but the reverse is not good.

However, the technology industry specializes in playing games. Game consoles do nothing else. In this way, it can be streamlined. Even using only an 8-bit CPU, it can make many classic games, such as super Mary.

They don't need a monitor. They can use a TV as a monitor. Because they only play games, the system of the game console can be quite simple. At the same time, it means more fluency!

When jobs was playing this game, he was also constantly thinking about how realistic the picture and how perfect the operation would be if the chips of Hanxin technology company were used as game consoles! It can be said that large-scale 3D games can run, but what about the current game console? It's just a two-dimensional plane game, which will be a cross era progress! He only plays games, so there is no conflict. At the same time, game consoles are also very popular in the western world.

Westerners like playing games, just as Oriental people like to set up tables to play mahjong, their game console market is often on the scale of millions.
