Since both parties knew the purpose of the meeting, after a little greeting, the Posacks immediately led the Alice family to their office.

On the way, Posack also explained their own situation. After all, this was the first time they had met James.

"We were originally affiliated with different departments of the computer department. When we contacted each other, we found that if there was no device like a router, it would be too troublesome to contact computers between different networks by email alone. So we started to study this project a long time ago, but we didn't expect that Alice would take the lead!"

No matter how Sandy spoke loudly, James listened very calmly. Alice looked at her family. It was very good. No one showed any special joy and no one could stand the praise, which gave her face.

But Hannah was a little special, always looking at the formal clothes of the couple. When everyone passed a corner, she pulled Alice's clothes and said, "It's not that they went to the restaurant for a banquet. Why are they wearing this well?"

Alice also had this question in her mind. After all, everyone knows what kind of life style of Silicon Valley workers are. Suddenly, people like Posack were actually wearing BOSS suits. Sandy changed into this year's new Chanel suit, which was really awkward.

"Sorry, the work area is always so chaotic. Just be careful at your feet. It doesn't matter what is on the table."

Soon, the Posacks took everyone into the teaching building and walked into a small office.

There were electronic components everywhere, or paper documents piled up to the ceiling, but as soon as Alice stepped into the house, she found a young man sitting in the corner without raising his head, reading something seriously.

"I'll introduce it to you."

When I came here, the home court became Posack himself, not Sandy: "Bill? Hey, Bill!"

Seeing the young man looking up blankly, Posack said: "This is a colleague from the same group as me, Bill Iger, who is very knowledgeable about information technology. Bill, this is..."

"You are Alice-Wang?"

Alice once again keenly discovered that the man was like Chen Jingrun, who seemed to be distracted all the time and spoke even lightly: "The genius girl who invented the cheaper, cheaper and smaller instruments that could connect to different networks?"

Alice: “………”

Oscar read Eagle's sentence gently and muttered: "What a long sentence, why didn't he fill in a few more attributions?"

Because most scientific geeks are like this, just look at the future American drama "Scorpio Network".

With a smile in his heart, Alice greeted Ig with decent manner.

Although he didn't know what this guy was, he really fits the image that a technical geek should have in Alice's heart: thick-framed glasses, unwashed hair for a week, stubble on his face, irreconcilable clothes with a sour smell, etc., which is much more qualified than the Posacks at this time.

"Oscar, Hannah, just sit there, be careful not to touch anything."

Sophie quickly arranged the two children. Although she was not an expert, she and James were of course present in the face of such a thing. The Posacks and Ig started to work hard and prepare for Alice's router function detection.

"The shell of the instrument is excellent, with a good texture and a matte texture..."

While busy preparing for the scene, Ig kept talking to himself, speaking lightly in a distracted tone, looking at it from time to time, stroking the dark shell of the router: "Are you looking for products made by a small factory? Miss Wang?"

"Just call me Alice, that... Leon?"

Without answering Ig's question, Alice whispered to Posack: "Is this Ig really capable? Are you planning to let him join our small group?"

"That's certainly, Iger can almost be said to be a pioneer in the field of computer information and communications. Although you have developed a router before us, he..."

But Posack's volume was not low at all. While plugging the computer network cable into the router, he whispered: "Ig, show Alice your work first. I guess her eyes will be like bullfrogs!"

"Oh well."

It was still the tone that seemed to be no longer in this world, Ig said lightly, and from some corner, he took out another rough-shaped metal box.

"Alice, this is my Jerry. Its design is the same as your router, but it is still a semi-finished product..."

When Alice saw that Eagle had taken out such an instrument, she didn't have the energy to think about anything else. She rushed to him in one step and held the box over.

How effective is this semi-finished product?

Of course, Alice is relieved to have a hundred products. Although it is limited to the times and many functions are not available, in terms of programming skills, it is definitely at the Windows-95 level!

But this is a competitor’s thing at least!

"It's not practical yet, I'm still programming it."

Ig's words made Alice's heart suddenly fall back, and he asked again: "By the way, you named your instrument Router. Is this a nickname or a product name?"

"Of course it's the name of the product, hey, the nickname is..."

"Oh, Alice, you have to know that many of my colleagues like to give their own products..."

"Ahem, Bill, why don't you listen to Alice first, she's already made the finished product."

"Oh well……"

It's still the light and fluttering tone that seems to be dreaming...

Oscar and Hannah have been sitting in the corner, but they have no boredom at all. After all, this is an office in the computer department of Stanford University. Whether it is the meaning of the term itself or the piles of heavy documents around it, it is enough to lift the two of their interests.

Of course, James and Sophie didn't understand the technical level, but seeing Alice, Posack and others gathered in front of a bunch of computers, of course they had to straighten their necks to observe the situation.

"Let me briefly introduce my design ideas first. The principle is this, Ig."

The computer was connected, but Alice didn't rush to operate it, but started to gesture on a piece of paper.

"First of all, the word route itself means route or road. The basic function of the router is to pass information from the source through the network to the destination. This... Hey, Oscar, Hannah, don't just spend time, Teacher Alice is giving you free lessons!"

"Okay sister!"

"Thut, annoying!"

"The routing process consists of two basic actions, namely, determining the optimal path and transmitting information through the network. In this process, the latter is also called data exchange. The exchange is relatively simple, but choosing the path is very complicated, right, IG?"

Ig nodded and said, "Yes, this is the difficulty I am currently conquering."

"As for the algorithm of routing, I only use the decimal method to determine the measurement criteria for the best path to the destination, such as the path length. Here, we also need to use a program called the routing table. I don't know if you have reached this point. Anyway, I have written a copy. I can show you later. It is stored in a router or networked computer and has a path to a specific network address."

"So, of course, every networked router is the provider and receiver of information. The routing algorithm fills the routing table based on many information. You should know that the so-called route selection is the best way to inform the router to reach the destination. The specific method is that the destination router sends the information packet to the host. When the host receives a packet, it checks its target address and tries to contact it."

Looking at Ig's thoughtful look, Alice continued to say: "As for the exchange algorithm, it is relatively simple. First of all, we need to set up a routing protocol, that is, a heterogeneous network interconnection mechanism. When a network's data packet is sent to another network, the router guides the path information of the IP packets to be sent. The so-called protocol is the provisions and standards agreed in advance in this process."

"Then, data exchange is based on this protocol, and data exchange is based on path selection. It is the best way to pass information between different networks!"

"Well, Oscar, Hannah, how much do you understand?"

Finally, Alice looked at her younger brother and sister in the corner.

Alice certainly didn't know what level she had studied, so at least half of the explanation she just said to the family members. After all, although she built the car behind closed doors, it only took a week. The so-called router is a magical thing, and they can understand a ghost!

However, even though she had explained as simply as possible, Alice still smiled bitterly and found that Hannah's eyes had long been replaced by a series of mosquito coils.

Oscar kept scratching his head and said slowly: "That routing algorithm, path selection, etc. are all math courses in college, right?"

A series of laughter suddenly rang out in the office, and Posack laughed and said, "Yes, yes, if you want to make great progress in the field of programming, you must learn mathematics to outstandingly!"

"Uh...I hate math..."

Alice never stepped out of this office the following afternoon. In addition to simply experimenting with various types of network interconnections, she also had to answer various design ideas to the three experts, especially Ig's repeated questions.

In just half an hour, Hannah forced Sophie to accompany her to walk on campus. Oscar was very interested in these experiments, and with James' patient company, she kept listening with wide eyes.

"So, the efficiency of the router is closely related to the CPU it uses, which is the largest part of the cost. Look at the latest version from Intel, $320, I dare to bet you that the cost is less than ten yuan!"

When he said this, Alice was really not vague at all. She knew it clearly that when Jobs first founded Apple, facing Intel's CPU of about 300 dollars, he forced the price to 75!

Three hundred, seventy-five, and Intel can still make money, it’s super huge profits!

Gradually, the sky outside the window was shrouded in twilight, with orange light spreading all over the earth, while there were only a few more students on campus, perhaps it was dinner time.

"This is huge profits, otherwise, how could Intel become the Fortune 100 companies in the world? You know, it was established in 1968."

Sitting on the computer chair, Posack sighed: "If you set up a company, I don't expect to make the company big. As long as you can popularize the router technology. After all, the industry we are engaged in is changing the world!"

"Yes, isn't this the case in the whole Silicon Valley? It's changing the world. How many founders with billions of dollars are just driving a second-hand Chevrolet to work... Wait, don't plan to make the company bigger!?"

Seeing Alice staring in shock, Posack shrugged naturally.

"Yes, as long as the technology can be spread, isn't it enough? Isn't it the highest enjoyment to sit in the office and watch your products change the world?"
Chapter completed!
