Siheyuan: My Northeastern Farmhouse

Chapter 448 There is still something

"Lin Suo!"

"Stop it, Gu Weijun, go out and turn left, go to the East and West Posts and Telecommunications Department, or drive all the way south, directly to Jiading, Shanghai, to find Unit 829. No, it's now renamed the Institute of Optical Precision Instruments. For your job, go find it directly They. They all have communications studies.”

"Aunt Lin."

"Hey, tell me." Old Mrs. Lin couldn't resist Gu Weijun's insistence. She closed the pen cap and crossed her hands on the desk. "Let me hear how you are going to convince me?"

Gu Weijun looked around mysteriously, lifted his butt off the chair, leaned forward on the table, and put his head next to director Lin Lanying, "Aunt Lin, don't I serve as the foreign mission of the Liaison Office in the United States?"

"." Mrs. Lin rolled her eyelids. Didn't I already know this?

"I got some not-so-secret news from the American Empire."

"Hurry up!" Old Mrs. Lin raised her hand to pat him.

"Well, the military department of the US emperor is already studying how to connect computers in different places through a network. They named it ARPANET!" Gu Weijun quickly said the key point, "They are still studying it through telephone lines or Use optical fiber to interconnect computers between different departments or regions! ”

"Oh? Please tell me in detail!" Old Mrs. Lin of Optical Fiber must know about it. After all, Gao Kun, a scientist from Hong Kong, published a related paper in 66. There are also related scholars in China doing related research.

"The U.S. military considers communication issues on future battlefields and coordination between different departments. Simply relying on telephones or radios may not necessarily accurately describe instructions or military plans."

"So they considered using computers to directly connect data, which is the ARPANET. There is news that in 71, the scientists who developed the ARPANET successfully used different computers in different locations. The network between computers, after compiling a communication protocol and software, sent the first email! "

"Aunt Lin, think about it. You can write a letter on the computer of the Institute of Semiconductor and have it sent directly to Shanghai, which is more than 1000 kilometers away. How convenient and fast will it be? How much research and discussion time can be shortened?"

"And this is just one of the by-products of studying ARPANET!"

"Think about it, do we have to catch up?"

"Bang!" Mrs. Lin slammed the table, "Weijun, why didn't you tell me about this earlier?"

"Why did it take so long to say it? What a delay?"

"I" Gu Weijun's mouth opened wide, he didn't know how to explain, it's only been a few days? Do we have to do things step by step? This small computer or computer hasn't broken through yet, so why are you in such a hurry?
Old Mrs. Lin has already shaken the phone, "Send it to the Department of Posts and Telecommunications! I am Lin Lanying!"

"Old Zhong, it's me, Lin Lanying!"

"Oh, let me make a long story short, have you ever heard of the ARPANET in the United States? Where's the fiber optic?"

"Okay, that's it"

Mrs. Lin explained to Chief Zhong in a few words the mutual communication and data transmission between emails and computers, as well as the data transmission and computer transmission of early warning aircraft radar.

"Okay, it's 10 o'clock in the morning. You first have a short meeting with the researchers from the Posts and Telecommunications Research Institute. I will take Gu Weijun to your office at o'clock in the afternoon to have a face-to-face meeting and study."

"Pah!" Mrs. Lin hung up the phone and asked Gu Weijun directly, "Have you brought your work notebook?"

After seeing Gu Weijun nod, Mrs. Lin pointed to a corner of her desk, "Sit here and transfer what you just told me about the network and emails before computers, including the radar data you mentioned at the beginning. "After writing it, we will go through it together, and then report it to Director Zhong of the Ministry of Posts and Telecommunications in the afternoon."

"Your message today is very crucial!"

"After reporting to Chief Zhong, I will ask Chief Zhong to report to the higher authorities on the new unit of chips and computers, and include this data communication as well!"

"Anyway, it's all gringo money, it's nothing if you don't use it."

"Uh~~~Okay." Gu Weijun secretly cursed in his heart. In fact, it's all my money. Alas, now I can only help the country in this way.

Like a primary school student, Gu Weijun sat obediently in the corner of Mrs. Lin's desk and wrote down what he learned about the American ARPANET, also commonly known as the local area network, in later generations. Of course, because he was not A computer major, he doesn't understand anything about the TCP/IP protocol.

But he understands some basic concepts of later generations of computers!

Sometimes the most critical thing in scientific research is the direction. Only with the right direction can we have good final results!
So Gu Weijun listed the problems that need to be solved according to different computers to solve data transmission: First, the miniaturization of computers. The United States already has small computers - computers, which are entering the trend of home use.

This trend is currently caused by computer games, and computers can also be used for home offices and commercial offices.

The main reason is that after the performance of computer hardware—microprocessors, storage, etc.—has been improved, computers can now play games and run office software smoothly.

Second, the operating system. The biggest difference between current computers is not only the hardware performance and different architectures, such as microprocessors, storage, integrated circuits, etc., but their instruction sets are also usually different, which leads to different operating systems. .

Therefore, in order to enable different computers to directly and smoothly communicate and connect data, a unified operating system is also necessary.

Finally, there is the issue of computer communication protocols. From how to communicate between computers in the same location through dedicated lines, that is, a local area network; to how to communicate between computers in different locations?
There is also the development of optical fiber. In the future, whether it is communication between telephones or computer network communication, it will be inseparable from optical fiber!

In addition, the further development of program-controlled telephones, which the Ministry of Posts and Telecommunications is most concerned about, is also inseparable from computers.

In short, Gu Weijun wrote a lot of things without hesitation.
When Mrs. Lin was looking at him, she kept looking sideways and looking at him strangely every time.
"Do you still have something in your stomach?" Old Mrs. Lin shook the warm report Gu Weijun had just written and praised it, "Especially this forward-looking one, it's very good!"

"It seems that the leaders above are really good at understanding people and making good use of them!"

"I really know your strengths!"

Mrs. Lin glanced at her watch and said, "Let's go to dinner, and then go to the Post and Telecommunications Department!"

It was another clear and healthy lunch, and Gu Weijun drove Mrs. Lin straight to the Ministry of Posts and Telecommunications.

The Ministry of Posts and Telecommunications building is on Dongsi. Mrs. Lin took Gu Weijun and drove straight to the director's office on the top floor by using facial recognition.

The office door was ajar, and Old Mrs. Lin pushed it open and walked in. "Chief Zhong, how was the discussion at your Post and Telecommunications Department meeting?"

"Let me tell you, the report I brought here today is definitely a bombshell for our Ministry of Posts and Telecommunications!"

Chief Zhong is an old man with a slightly larger head, short stature, and a bit stubby. His eyebrows and hair are already sparse.
Commander Zhong was very excited when he heard this. He spoke with a thick Guangxi accent and said, "Xiao Lin, what good news does Li Zemo have?"
