Blue Star Sea Diamond

This large antenna is installed in a nearby power plant and transmits and receives signals into the universe. The control source is on his strange game console. Any information he enters on the command line is transmitted to space. According to the instructions , It takes a very long time to wait for the reply after sending the radio signal.Most people can't wait for the time to receive the reply, and may be received in future generations, so this is a transmission device with a large span in space and time.

The person connecting the big antenna is called Ji Dan, who is responsible for all the network and radio system engineering in this city.Liu Chengyi is very interested in him and wants to learn about this machine from him.

Liu Chengyi said: "Is there any rule between the link line and the transmission?"

Ji Dan said: "Connect the two computers, get acquainted, and then send messages. How to connect computer A and computer B? Use an internet cable directly. No, except that they have to connect to a box that can be connected to each other. How do the boxes that are connected to each other connect? The box must be able to connect to the two computers to send signals, and the signals sent by both computers must be able to recognize, and the two computers must also pass through this box to make sure that each other is indeed each other? The box is C .A is connected to C, and A can scan for the existence of C in the command line. The existence mode is port or virtual port. How to determine that C is connected to A and C is not connected to A can be scanned, look at the network cable, when the network cable is connected, There is a specific path and resistance change on C. How to determine it? After A has set up this certain mode, after setting up this mode, there is a list corresponding to the part of the table related to C, and then start to start Something related to C. Find another table that connects C to B. After A is sent to C, C is sent to B. After B has a reaction, the table of B is started, the table of B is against C, and the table for A is Table, and then start the corresponding operation, and then B will give Frank things to A."

Liu Chengyi said: "This is a protocol, how is the best thing to transmit?"

Ji Dan said: "One machine transmits to another machine. The richer the machine, the more complete the tables it contains, the less the amount of signal to transmit. The simpler the machine, the fewer tables it contains, the greater the amount of signal. If you want to increase the amount of semaphore, just write the corresponding form in the terminal, so that simply pass something, you only need a few signals. If the terminal form is small, it will pass a lot of signals, so two The signals of different things are transmitted between computers, and the number of tables corresponding to the computer is already a balanced optimal value. If this is not the case, it will be inefficient or waste resources."

Liu Chengyi said: "Is this machine used for several generations?"

Ji Dan said: "Not exactly, because there are many received here, so many of the received are also hundreds of years ago. It is amazing to see the ancient records recorded by this ancient man hundreds of years ago. It’s just like Frank came just now. I can only rely on this self-consciousness to reply to a message that only others can see for a hundred years. Isn’t it like this? It’s also difficult to verify."

Ji Dan also found and bought this other book on game science in an enthusiast game store. It was an authoritative book introducing this device. The book said that this device is dedicated to many alien races. Great, and the version he is playing now is very old, but the function is not obsolete, the machine does not upgrade over time, this game can talk to many aliens of various races, this is not a simple The game is a blueprint for exploring the management of the universe, trade, and military affairs based on the game.

Liu Chengyi said: “Will there be a universal interpretation agreement that does not need to be troublesome to understand the language of the other party, but to interpret it by oneself, using artificial intelligence and other methods to use interpretation."

Ji Dan said: "This kind of agreement can interpret any agreement that he has never encountered before."

Liu Chengyi said: "It's so good and convenient."

Ji Dan said: "After judging that the unnatural signal from the depth space is a network protocol, we will seek the best processing method and use it as a transit station."

Liu Chengyi said: "Transfer station, why."

Ji Dan said: "It is equivalent to the role of a router."

Ji Dan said: "The theoretical question raised is whether it is possible to use logical methods to study, classify, use, and judge the meaning of the agreement without understanding the language and the language. And use."

Liu Chengyi said: "Can we speculate that other aliens already have this?"

Ji Dan said: "There must be, many possibilities are certain, and we will be like this. This problem has been solved by generations of mathematicians."

Liu Chengyi said: "Will there be any mathematical basis?"

Ji Dan said: "There can be many. For example, after the password is solved, the meaning of the agreement can be accelerated according to the characteristics of the error correction code."

Liu Chengyi said: "Is it possible to actually judge?"

Ji Dan said: "After sending it many times, you can review the agreement. Although it can't be traversed, the important content can be inseparable."

Ji Dan went on to say: "The second theoretical question is, what is the possibility of error, and can the error be controlled within a certain range, so that the error is not too outrageous. The alien made a structure similar to the TCP/IP protocol? What’s the probability of network transmission? According to calculations, it’s actually very large."

Liu Chengyi said: "These problems are very interesting, we can use the transmitter to analyze. This plan can be carried out by multiple parties, the universe network plan, the analysis of the universe signal, the scrutiny of the transmission and transmission protocol, calculation integration, network optimization, etc. doing."

Jiang Shan said: "If you are more interested in this issue, I can take you to a place."
