Chapter 117 Do You Want to Engage in the Internet?
After wandering for several days, Zhao Ye once again came to the research institute he visited last year.
There is almost no change in the appearance here, but the atmosphere here seems more tense than last time. It is already January of the 63rd year of the Gregorian calendar, less than two years since that day that shocked the world.
The tighter the time, the more Zhao Ye hopes that his efforts can do something for these people.
This time, 12 pieces of equipment were sent. Compared with the first generation, the performance of this Shuguang 2 is several times that of the first generation machine.
It was still the same computer room, on the side of Shuguang No. 1. Zhao Ye and the technicians from the factory began to install the equipment brought this time.
Throughout the afternoon, Zhao Ye was busy with people in the factory. The computer room administrator here has been replaced, and Zhao Ye doesn't know anyone, so there are less exchanges between the two parties. Everyone is immersed in their work, and there is very little communication.
say.
It wasn't until night fell that Zhao Ye and the others completed the installation and debugging of all the "computers".
Zhao Ye and the people in the factory were preparing to take a rest. At this time, the door of the computer room was pushed open. A familiar face came into view, and Zhao Ye immediately felt less tired again.
"Haha, classmate Zhao Ye, thank you for your hard work!" The same tall and thin man came forward to shake hands with Zhao Ye enthusiastically.
"Professor Lu, I see you again!" Zhao Ye was so excited that he lost his composure, and his voice was distorted.
"Yeah, I'm very happy to meet you too. You are someone who has made outstanding contributions to our work! So, as soon as I heard that you were coming today, I rushed over immediately. Tell me quickly.
Tell me about your new achievements!" The tall and thin man smiled and urged Zhao Ye to quickly introduce them to the new computer.
"Okay, the equipment has just been debugged. Let me demonstrate it to everyone." Speaking of the new computer, Zhao Ye was also proud. This was their new achievement during this period. It would be really hard not to show it off.
"Professor Lu, seniors, our new model is named Shuguang 2. It is developed on the basis of Shuguang 1. There is continuity in operation. All the instruction sets we used before have been transplanted.
On the new model. Therefore, the operation commands in the past are also applicable to the new model."
Everyone nodded, which means that the previous operating habits and methods can still be retained, which is more convenient.
"Of course, our new models have also added some new instruction sets, and accordingly, some additional operating commands have been added. This is mainly because our new models have added some new functions."
With that said, Zhao Ye had already started up a computer, and then motioned to other staff members to turn on other machines.
"Look here, we call this device a data switch. Its main function is to connect several computers and allow them to perform parallel operations."
After hearing this, many people in the room had already taken out their notebooks and recorded the key points that Zhao Ye said. Professor Lu was also listening carefully. At this time, he also interjected and asked: "Can you elaborate on this?"
What are the principles and functions of parallel computing?”
"Well, this multi-machine parallel computing is the inspiration I got here last year. Everyone knows that the No. 1 machine is easy to burn out when the amount of data is too large. At that time, an administrator comrade said that if the machine
The capabilities of two computers can be added together! So I went back and worked with our project team to develop this function."
"In other words, parallel computing means combining the computing power of several computers?" someone in the crowd asked.
"That's it! What we can do at present is six machines in parallel. One of the computers is used as the main computer, responsible for splitting and summarizing the calculation data, and allocating other computers to perform calculations. This computer is equivalent to a calculation command center.
The data is distributed to five other computers for calculation, and after the other computers complete the calculation, the data will be sent back to the command center for deployment until the final result is produced."
"Then doesn't this mean that the capability of Unit 1 has been expanded to five times before?"
"Haha, strictly speaking, it has expanded the capability of Unit 1 by twenty times!" Zhao Ye said proudly.
"Huh? Why is this?" Even Professor Lu was a little confused this time.
"This is because our Dawn 2 itself has also been upgraded, although our processor technology has been limited in its improvement due to problems with manufacturing equipment.
However, we have also done parallel processing on the processors. The current Shuguang 2 has four processors. Theoretically speaking, the computing power of one Shuguang 2 is four times that of the No. 1 machine. So combining five processors will not
Is it twenty times?
Of course, this is only theoretical. In actual operation, it is only about ten times that of the previous one. Because of the problem of data interaction, multi-machine parallelization will have some computing time differences, resulting in a certain reduction in efficiency."
"Wow wow wow!" There was a round of applause!
"It's amazing, it's amazing. In one year, you were able to improve the capabilities of new equipment so much. You asked, and you made an amazing achievement!" Professor Lu was also applauding. He really felt for my country's microelectronics research. Happy.
In one year, there has been such great progress, which is amazing!
Zhao Ye listened to the applause and applauded himself.
After everyone's applause stopped, Zhao Ye continued to introduce the hard disk connection function, which can easily access data, especially large data. This can greatly improve the application range of computers.
Then all the No. 2 machines can be interconnected through data switches. Although parallel computing can only support five machines, there is still no problem in sending data to each other.
This function is so practical. It will save everyone so much time! So they all asked Zhao Ye to demonstrate how to send it!
Zhao Ye didn't care, he immediately took out a floppy disk and stuffed it into a computer.
"What is this?" Professor Lu asked.
"This is another function of ours. This thing is called a floppy disk. Inside this hole is the floppy disk reader and writer. You can use this device to read the data stored in the floppy disk into the computer."
"In that case, are floppy disks equivalent to mainframe paper tapes?"
"That's true!" Zhao Ye replied.
"Oh!" The man quickly wrote it down. He had never used this or a floppy disk, so he didn't say which one was more useful. But he felt that this one was more advanced, otherwise it would be meaningless.
"How much data can this floppy disk store?" someone else asked.
"Theoretically, this floppy disk can store 32kb of data. Of course, the actual available space is not that large, and it can only store a maximum of about 27,500 bytes." As he said that, Zhao Ye started operating on the computer.
There is still the familiar command line interface on the screen, but this time the screen is larger.
"Start:A://"
As the execution button is pressed, the screen quickly displays:
"A:
(1) Shuguang-2 operating command set
(2) Shuguang 2 Maintenance Guide”
Zhao Ye paused here for a moment, then used the arrow keys to select a file name, and then pressed the execute button. At this time, an article introducing the Dawn-2 operating commands was displayed on the screen.
"Ah! I can still save Chinese characters!" someone shouted.
"Aren't you talking nonsense? Chinese characters are not data?" Another person said with "disdain" to him. Although he said this, he was very excited in his heart. This is so convenient, so convenient!
Then Zhao Ye pressed the return key again and returned to the selection line at the beginning.
Then use the arrow keys to move the cursor to the bottom and enter
Send://A:/(1),(2)/ to 101.0.0.023//
Press the execute button again, and the words "OK" are immediately displayed on the screen of a computer next to it.
"Receive data from 101.0.0.022? (Y/N)"
Zhao Ye pressed the "Y" button on another computer. The name of the received file was immediately displayed on the screen.
"Wow, wow, wow" was another round of applause!
Everyone is very happy about this function. These computer researchers are so considerate. It is so convenient to come up with such a function.
"Zhao Ye, what do you mean by this line of numbers?" Professor Lu asked, pointing to the screen.
Zhao Ye took a look and saw that it was the IP address he entered. Then he explained again.
"We call this an address, and you can understand it as the number of the data switch in this computer. Now we connect these computers through wires and switches, and then a network is formed. In this network, this string
The number is the address, number, or name of each device."
"Oh!" Everyone nodded and took note of it carefully.
"Hey? How big can this network be? How far is it? Wouldn't it be convenient if all the computers here were connected?"
There is always a shortage of smart people here, and this reminds me of the "Internet"! But Zhao Ye is disappointing, and it's not working yet.
"Well, in theory it is possible, but the voltage provided by the switch is very small and cannot transmit data over long distances." Zhao Ye replied.
"This is simple, just amplify the signal current!"
"It's not just a matter of signal strength, the key should be the carrying capacity of the switch. Think about it, a switch can only carry six computers, plus the interconnection between switches, I think technically this should be
There is a limit," another person in the crowd said.
"This is not a problem. You can just use a computer and a switch to interconnect various sites, and then share the data with our computers through this computer!" Who?
He said unconvinced.
Zhao Ye was dumbfounded when he heard this. Isn't this the Internet! Are you sure you are trying to get Miss Qiu? You are not from time travel, are you? Are you trying to get the Internet? I don't even dare to think about it!
