Siheyuan: The Era of Core Generation

Chapter 120 Do You Want to Engage in the Internet?
After wandering around for several days, Zhao Ye came to the research institute he visited last year again.

There is almost no change in the appearance here, but the atmosphere here is more tense than last time.It is now January of [-] in the Gregorian calendar, and it has been less than two years since that shocking day.

The tighter the time, the more Zhao Ye hoped that his efforts could do something for these people.

This time, 12 devices were sent. Compared with the first generation, the performance of this Dawn No. [-] is several times that of the first generation.

In the same computer room, on the side of Shuguang No. [-], Zhao Ye led the technicians from the factory to start installing the equipment he brought this time.

Throughout the afternoon, Zhao Ye was busy with the people in the factory.The administrators of the computer room here have changed, and Zhao Ye doesn't know any of them, so the communication between the two parties is less.Everyone is buried in their work and rarely speaks.

It wasn't until night fell that Zhao Ye and the others finished installing and debugging all the "computers".

Zhao Ye led the people in the factory to go to rest, but at this time the door of the computer room was pushed open.A familiar face came into sight, and Zhao Ye immediately felt less tired again.

"Haha, Zhao Ye, thank you for your hard work!" The same tall and thin man enthusiastically stepped forward to shake hands with Zhao Ye.

"Professor Lu, I see you again!" Zhao Ye lost his composure in excitement, and his voice was distorted.

"Yeah, I am also very happy to meet you. You are a person who has made outstanding contributions to our work! So, as soon as I heard that you are coming today, I immediately rushed over and told me quickly Talk about your new achievements!" The tall and thin man smiled and urged Zhao Ye to quickly introduce them to the new computer.

"Okay, it just so happens that the equipment has been debugged. Let me demonstrate it to everyone." Speaking of the new computer, Zhao Ye is also proud. This is their new achievement in this period of time. It is really itchy to not show it off.

"Professor Lu, seniors, our new model is named Shuguang No. [-], which is developed on the basis of Shuguang No. [-]. It is in operation, and there is continuity. All the instruction sets we used before are transplanted. It is on the new model. Therefore, the operation commands in the past are also applicable to the new model.”

Everyone nodded, that is to say, the previous operating habits and methods can still be preserved, which is more convenient.

"Of course, our new model has also added some new instruction sets. Correspondingly, some operating commands have also been added. This is mainly our new model, with some new functions added."

As he said that, Zhao Ye had started a computer, and then signaled to other staff members to turn on other machines.

"Everyone look here, this device, we become a data switch, its main function is to connect several computers and let them do parallel computing."

Hearing this, many people in the room have already taken out their notebooks and recorded the key points Zhao Ye said.Professor Lu was also listening carefully. At this time, he interjected and asked, "Can you explain the principle and function of this parallel computing in detail?"

"It's like this. This multi-machine parallel computing is the inspiration I got here last year. Everyone knows that the No. [-] machine is easy to be burned when the amount of data is too large. At that time, a comrade administrator said that if several 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 is to combine the computing power of several computers?" asked a person in the crowd.

"That's right! At present, what we can achieve is six computers in parallel. One of the computers is the host computer, which is responsible for splitting and summarizing computing data, and deploying other computers for computing. This computer is equivalent to a computing headquarters. The data is distributed to the other five computers for calculation, and after the other computers complete the calculation, the data will be sent back to the headquarters for deployment until the final result is produced."

"Then doesn't this mean that the capacity of No. [-] machine has been expanded to five times before?"

"Hehe, strictly speaking, the capacity of No. [-] machine has been expanded by twenty times!" Zhao Ye said proudly.

"Huh? Why is that?" Even Professor Lu was a little confused this time.

"This is because our Suguang-[-] itself has also been upgraded, although our processor technology has limited improvement due to manufacturing equipment problems.

However, we have also done parallel processing on the processors, and the current Dawn-[-] has four processors.Theoretically speaking, the computing power of a Dawning No. [-] is four times that of the No. [-] machine.Then the United Five, isn't it [-] times?

Of course, this is only theoretical. In actual operation, it is only about a dozen times the previous one.Due to the problem of data interaction, multi-machine parallelism will have some computing time difference, resulting in a certain reduction in efficiency. "

"Huh, huh, huh!" There was applause at the scene!
"It's amazing, it's amazing. In one year, you can improve the capabilities of the new equipment so much. You asked me to make a great achievement!" Professor Lu was also applauding. He really felt for my country's microelectronics research. Happy.

In one year, there has been such a big improvement, which is amazing!
Hearing the applause here, Zhao Ye applauded himself.

After everyone's applause stopped, Zhao Ye continued to introduce.The hard disk connection function can access data very well, especially large-scale data.This can greatly improve the scope of application of the computer.

Then go to all the No. [-] machines, which can be interconnected through data switches.Although parallel computing can only support five units, it is no problem to send data to each other.

This feature is so useful, how much time will it save everyone!So they all asked Zhao Ye to demonstrate the sending method!

Zhao Ye was also unambiguous, and 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 a floppy disk reader. Through this device, the data stored in the floppy disk can be read into the computer."

"So, is the floppy disk equivalent to the paper tape of the mainframe?"

"That's true!" Zhao Ye replied.

"Oh!" The man quickly wrote it down.He didn't use this or any floppy disk, so he didn't say which one was better.But I feel that this is more advanced, otherwise it would be meaningless.

"How much data can this floppy disk store?" Someone asked again.

"Theoretically, this floppy disk can store 32kb of data. Of course, the actual usable space is not so large, and it can only store about 27500 bytes at most." After speaking, Zhao Ye began to operate on the computer.

The familiar command line interface is still on the screen, but this time the screen is bigger.

"start: A://"

As the execute button is pressed, the screen quickly displays:

"A:

(1) Dawn-[-] operation command set
(2) Suguang II Maintenance Guide"

Zhao Ye paused here, then used the arrow keys to select a file name, and then pressed the execute button.At this time, an introduction article on the operation order of Dawn No. [-] was displayed on the screen.

"Ah! I can still save Chinese characters!" one person shouted.

"Aren't you talking nonsense, Chinese characters are not data?" Another person "scorned" him and said, even though he said so, he was very excited in his heart, this is convenient, so convenient!

Afterwards, Zhao Ye pressed the back button 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 a line of words is displayed on the screen of a computer next to it.

"Are you receiving data from 101.0.0.022? (Y/N)"

Zhao Ye pressed the "Y" button on another computer.The name of the received file is immediately displayed on the screen.

"Huh, huh, huh" was another burst of applause!
Everyone is delighted with this function. These computer researchers are so considerate. It is really convenient to come up with such a function.

"Zhao Ye, what do these numbers mean?" Professor Lu asked, pointing at the screen.

Zhao Ye saw that it was the IP address he entered.Only then did it explain again.

"We call this the address. You can understand it as the number of the data switch in this computer. Now we connect these computers to the switch through wires, and then a network is formed. In this network, this string The number is the address or number, name of each device."

"Oh!" Everyone nodded, and then seriously wrote down.

"Hey? How big can this network be? How far away? Wouldn't it be convenient if all the computers here were connected!"

There will never be a lack of smart people here, which brings to mind the "Internet"!But Zhao Ye is disappointing, and it's not working yet.

"Well, it is theoretically possible, but the voltage provided by the switch is very small, and it cannot transmit data over long distances." Zhao Ye replied.

"This is also 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 this should be technically There's an upper limit," said another person in the crowd.

"This is not a problem, you can just take out a computer and switch, just use it for the interconnection of various stations, and then share the data with our computers through this computer!" Said unconvinced.

Zhao Ye was dumbfounded when he heard that, isn't this the Internet!Are you sure you are messing with Ms. Qiu?Could it be that they also came from time travel?Do you want to engage in the Internet?I didn't even dare to think about it!
