A few days later, the design plan was finally brought out for a long time.

"You have won the first prize of the National Progress Award? I now believe that this thing is not something that ordinary people can make. The old director looked at something for a long time and was secretly surprised.

"I don't know, it seems that someone else has applied for it. "Touching my head for a long time, it feels like I haven't had a haircut in a long time.

"What a hero, tsk. "The old director is very envious.

"No, just do it. ”

"No problem, just change it and add something. The old director carefully reviewed the drawings and nodded incessantly.

"?" wondered for a long time, "What's the matter?"

"Communication components, inspired by you, I thought of a way, since there are more processors, wouldn't it be better for multiple computers to communicate with each other. ”

"Networking!Sharing data!Data link!" It's a surprise for a long time, looking at this handsome old guy I really can't wait to go up and take a bite, this is a fateful door.

Computer networking has been around for a long time, but people haven't seen the benefits of it, and it's very small, mainly used on mainframes in universities.

As for the Internet, it is even later, and the great development of the Internet was still in the 90s, and in a broad sense, it still entered thousands of households together with microcomputers.

The 80s did rise to the microcomputer craze, but it wasn't until after the 90s that the concept of home computers really came into being, which indirectly promoted the development of the Internet.

I've been wanting to build a LAN or something for a long time, but I don't have time, and second, my computer standards haven't been established, so everything is nonsense, so I put it on hold.

Now when I heard that the old director actually had something similar here, wouldn't I like to fall from the sky.

"Sharing? Yes, it's sharing data, all the computers are connected together, and I have what you have, that's the truth. The old director met his bosom friend and nodded excitedly, "Not only the computer must be connected, but all the equipment must be connected." The radar finds the target, transmits it to the computer, and then controls the transmission mechanism to let the radar track. All data are processed by the computers of each department at the same time through sharing, each performing its own duties, counting the trajectory of the ballistic, and the control of the control, so that even if the computing power of the single machine is weak, the collection can meet the needs. ”

"You can also make a special computer for analysis, use the plane to take pictures on the spot in the early stage, the photos are converted into data information, and a database can be established, all the terrain data can be shared, and the artillery in front can shoot through this model data, and you don't have to worry about the calculation at all, you only need to adjust the gun position, God, isn't this a digital map!"

"Well, the idea is good and worth promoting. It seems that the people at the Geodetic Survey also have such a study, how to use computers to process map data. The old chief smiled, as if he had seen the enemy being bombed, "In this case, the artillery preparations can advance for at least a minute." ”

"So what are you waiting for? Chang Chang hurriedly said, "Where are the things we are connected to, I want to see." ”

～～～～～

"......" was speechless after looking at the real thing for a long time, "This is the communication network you are talking about?"

"Yes, is there anything else?" the old director was also inexplicable, feeling that this kid and himself were not the same thing.

The network that the old director said is just a simple transmission of data between two computers using a teletypewriter through a telephone line, one is slow, and the other is not able to exchange data in real time, and it is still in a relatively primitive state. I've seen this thing in the computing office for a long time, but because the teletypewriter doesn't fit his aesthetics, he doesn't pay much attention to it.

It's been a long time to be discouraged, he thought that Huaxia Technology had developed a local area network, and after all, this is it, so he couldn't help but sigh.

"What's wrong. The old director was still in high spirits at first, but after a while, he withered, and couldn't help asking, "What's uncomfortable?"

"It's nothing, it's just upset. "It's a little gloomy for a long time, but then I thought to myself, the network is also man-made, isn't it just protocol and moderation, why can't I do it myself?

It's hard to get started, let's go simple, just use the phone line. I remembered it for a long time, and I was fortunate to have learned various protocols in my dream, such as network protocols and routing protocols.

It seems that the important thing in the future is TCP/IP, but fortunately, I have been working hard for a while for a long time, and I didn't go to an Internet café with those classmates.

"This doesn't work, we have to redesign it to be simple and effective. Long and resolutely said to the old director.

“！”

The long-term idea was to introduce the concept of a local area network, using a local area network to connect computers together.

LAN appeared in 1972 at Xerox Labs (where it seems that many of the technologies originated), and by 77 years it had developed into a network with more than 100 nodes and more than 1,000 meters long.

At the time, it was called "Ethernet" and was inspired by the idea that electromagnetic radiation could propagate through luminescent ether.

However, the technology at that time was not good, and it was a thick coaxial cable, which was very cumbersome. But the basic transmission method has been finalized, which is to divide the data into packets and send them to networked machines.

In fact, the LAN we are talking about now is also Ethernet, because this has become the de facto standard. But in '80, there were dozens of different networking standards, and Ethernet was just one of the humble little things.

However, thanks to the participation of two large companies, Intel and DEC, a series of standards have been jointly developed, and Ethernet has developed step by step.

Not only that, but several very good network providers made a big mistake in the market, and handed over this big cake to others, so that it has the status of today's Ethernet.

I remember clearly for a long time that in 80 years Intel and DEC, by the way, and Xerox, will release version 1.0 of the Ethernet LAN link and physical layer specification.

I definitely can't grab it now, but we can borrow it, I thought about it for a long time. Now that the market is so chaotic, Ethernet is inferior to others in terms of technology and speed, who would have thought that such a thing would become the standard in the future.

It's a pity that Cao Changjiu knows, not only knows, but also knows very well, so there is no need to take a detour now.

Ethernet technology is mainly carrier communication, but also has automatic collision detection and multi-point transmission functions, its technology is not complicated, but this thing was patented by the founder of Ether in 77.

However, there should be no problem in doing it in his own country, and he returned to the studio for a long time and began to think about the structure of this set of things, but he is not too familiar with carrier communication, and there are still many doubts that cannot be solved.

The old director watched the long time go back to the office, and he couldn't rest assured, so he followed all the way, but saw a long time biting a pencil there in a daze.

After a while, the pencil was bitten and bruised, and the old director couldn't stand it anymore, so he went up and patted it for a long time, and asked, "Are you okay, do you want to take a break." ”

After a long time, the fugue returned, "Director, is there something wrong?"

"What do you think? ”

"I think something on the carrier, it doesn't work. ”

"Carrier?" the old director's eyes widened, "You don't have a fever, don't you look at what we're doing here!"

Debt!
