The Goddess Shines on America

　　 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 there, Posack also explained their own situation. After all, this was the first time they saw James.

"My husband and I belonged to different departments of the computer department. When we contacted each other, we found that it would be too troublesome for computers between different networks to communicate by email without a router-like device. So we started researching a long time ago. This project, I just didn't expect it to be a step ahead of Alice!"

　　 Regardless of how Santi spoke in a high tone, James listened very indifferently. Alice looked at her family, very good, and no one showed a particularly happy and uncomfortable appearance, which gave her a lot of face.

　　 It’s just that Hannah is a bit special, always looking at the formal clothes of the couple. When everyone passed a corner, she tugged Alice's clothes and said, "It's not going to a restaurant for a banquet. What are they doing so well?"

　　 Alice also has this question in her heart. After all, everyone knows what the life style of Silicon Valley workers is. It is too awkward to see that people like Boss are wearing BOSS suits, and Santi is wearing this year's new Chanel suit.

　　 "Sorry, the work area is always so messy. Just pay attention to your feet. It doesn't matter what is on the table."

　　 Soon, the Possacks led everyone into the teaching building and into a small office.

　　 There are electronic components everywhere here, or else, paper documents piled up on 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 will introduce you to you."

　　 Come here, the home game becomes Posak himself, not Santi: "Bill? Hey, Bill!"

　　 Seeing the young man looking up blankly, Possack said, "This is a colleague in the same group as me, Bill Iger, who has a lot of research on information technology. Bill, this is..."

　　 "You are Alice-King?"

Alice once again keenly discovered that this man is just like Chen Jingrun, who seems to be distracted all the time, and speaks lightly: "The one that invented the cheap, cheap and small instrument that can connect to networks of different standards a step earlier than us. A genius girl?"

　　Alice: "……"

　　 Oscar lightly read Yige’s sentence, and muttered: "It's a long sentence, why doesn't he fill in a few more attributives?"

　　Because of Frankenstein, most of them are like this, just look at the future American drama "Scorpio Network".

　　 smiled secretly in her heart, and Alice greeted Ignatly with a decent manner.

Although I don’t know what the **** this man is, he really fits the image of a technical geek in Alice’s mind: thick-framed glasses, hair that hasn’t been washed for a week, stubble on his face, and sour stubble. The clothes are much more qualified than the Posacks at this time.

　　 "Oscar, Hannah, you two should just sit there. Be obedient and don't touch anything."

　　 Sophie quickly arranged the two children. Although she is not an expert, she and James must of course be present in the face of this kind of thing. But the Possacks and Ignatius got busy, preparing for Alice's router function test.

　　 "The outer shell of the instrument is very good, with good texture and matte texture..."

While busy preparing for the scene, Yige kept talking to himself, talking lightly in a distracted tone, and from time to time he looked and stroked the dark shell of the router: "Are you looking for a product made by a small factory?" Miss Wang?"

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

　　 did not answer Yige’s question, Alice whispered to Bosak: "Is this Yige really capable? Are you planning to let him join our small group?"

　　 "Of course, Ignatius can almost be said to be a pioneer in the field of computer information communication. Although you have developed a router before us, he..."

But Bosak’s volume was not low at all. While plugging the computer network cable into the router, he said loudly, “Yig, first show Alice your work. I guess her eyes will look like bullfrogs. of!"

　　 "Oh, good."

　　 is still in the same tone as if he is not in this world, Yi Ge said lightly, taking out another rough metal box from which corner.

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

　　 Seeing Yige actually take out such an instrument, Alice rushed to him in one step and took the box over, wherever she had the energy to think about other things.

　　 How is the effect of this semi-finished product! ?

　　Of course, Alice is 100% assured of her products. Although limited to the times, many functions are not available, but as far as programming skills are concerned, it is definitely at the windows-95 level!

　　 But it's a competitor's thing anyway!

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

　　 Ignatius’ words made Alice’s heart suddenly suspended, and he immediately asked: "By the way, you named your instrument Router. Is this a nickname or the name of the product?"

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

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

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

　　 "Oh, good..."

　　 is still that light and fluttering, as if you have been dreaming...

　　 Oscar and Hannah have been sitting in the corner, but they don't feel bored at all. After all, this is an office of the Department of Computer Science at Stanford University. Whether it is the meaning of the term itself or the surrounding piles of heavy documents, it is enough to lift their interest high.

　　 James and Sophie certainly don't understand the technical level, but watching Alice, Boss and others get to a bunch of computers, of course they have to straighten their necks and observe the situation.

　　 "Let’s briefly introduce my design ideas, the principle is like this, Yige."

　　 The computer was connected, but Alice did not rush to operate, but first made gestures on a piece of paper.

"First of all, the word route itself does not mean a route or a road. The basic function of a router is to transmit information from the source through the network to the destination. This point... Hey, Oscar, Hannah, don’t patronize Play, teacher Alice is giving you free lessons!"

　　 "Good sister!"

　　 "Cut, annoying!"

"The routing process includes two basic actions, namely, determining the best path and transmitting information through the network. In this process, the latter is also called data exchange. The exchange is relatively simple, but the path selection is very complicated. Right, Ignatius?"

　　 Yige nodded and said: "Yes, this is the difficulty I am currently overcoming."

"As for the routing algorithm, I only use the decimal method to determine the measurement standard of the best path to the destination, such as the length of the path. Here, we also need to use a program called routing table, I don’t know. Have you reached this point? Anyway, I have already compiled a copy. I can show it to you later. It is stored in a router or a networked computer with a path to a specific network address."

"So, of course, every networked router is both a provider and a receiver of information. The routing algorithm fills the routing table based on a lot of information. You should know that the so-called routing is to tell the router to reach the destination address pair. The best way for the purpose. The specific method is that the destination router sends the information packet to the host. When the host receives a packet, it checks its destination address and tries to contact it with this address."

Seeing Iger’s pensive appearance, Alice kept saying: “As for the exchange algorithm, it is relatively simple. First, we need to set up the routing protocol, which is the heterogeneous network interconnection mechanism. When a network When a data packet is sent to another network, the router instructs the path information of the IP data packet. The so-called protocol is the pre-appointed regulations and standards in this process."

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

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

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

　　 To what extent the Possacks have studied, Alice certainly doesn't know, so at least half of her commentary just now was for the surrounding family members. After all, although I built this car behind closed doors, it was only a week before and after. The so-called router is a magical thing, they can understand a ghost!

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

　　 And Oscar kept scratching his head, and said slowly: "The routing algorithm and the path selection are all university mathematics courses, right?"

　　 A series of laughter suddenly sounded in the office, and Bosak laughed: "Yes, that's right, if you want to develop in the field of programming, you must excel in mathematics!"

　　 "Uh...I hate math..."

In the following afternoon, Alice never stepped out of this office again. In addition to simply experimenting with various types of network interconnection, she had to ask three experts to answer various design ideas, especially Yi Ge San. Questions four times.

　　 In less than half an hour, Hannah forced Sophie to accompany her on a walk on the campus. Oscar was very interested in these experiments. UU Reading www.uukanshu.com, accompanied by James patiently, always watched with his eyes wide open.

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

When 　　 said these words, Alice was truly unambiguous. She knew very well that when Jobs first founded Apple, facing Intel's same CPU of about $300, he abruptly cut the price to seventy-five!

　　 Three hundred, seventy-five, and Intel can still make money, super profitable!

　　 Gradually, the sky outside the window has been shrouded in twilight, and the orange light is all over the earth, but there are only a lot more students on the campus, maybe it is dinner time.

　　 "This is huge profits. Otherwise, how could Intel become the world's top 100 companies? You know, it was established in 1968."

Sitting on the computer chair, Possack said with emotion: “If I set up a business, I don’t expect to make the company much bigger, as long as the router technology can be popularized. After all, the industry we are working in is in Change the world!"

　　 "Yeah, isn't it the same in the entire Silicon Valley? Change the world, how many billionaire founders can only drive a second-hand Chevrolet to work... Wait, don't plan to make the company bigger!?"

　　 Seeing Alice staring in surprise, Bosak shrugged naturally.

　　 "Yes, as long as the technology can be spread out, it's OK? Sitting in the office and watching your products change the world, isn't this the highest enjoyment?"
