"Calm down, calm down, that's just a first-hand product. In fact, you can do it even if you study it more!"

"Hey, drive slowly! Hey, it's a red light!"

Unexpectedly, the driver of the car was Mrs. Posack, not Mr.. But when Alice sat in the back of the Buick car driven by Sandy, she had to hold the back of the front seat with one hand, stared at the road ahead with her eyes, and kept shouting.

"You actually exceeded three cars in five seconds! Do you think you are playing Grand Theft Auto or Need for Speed!? Oh, don't ask me what that is, EA is still in the womb now! No, it seems that it has been established in 1982...Oh!"

"My home is Vinton Street in Culver City! What are you driving on the pilgrimage to Monica Expressway?? Hey, which direction did you turn... Hey! Is this a turnaround line??"

When Sandy realized that she was going the opposite direction, she turned around 180 degrees on the double yellow line without saying a word. The powerful tail swing was extremely outstanding, and she called Oscar, who was in the back row, and she could only complain.

Motion sickness? That's not.

Do students of the three good abide by traffic regulations? That's not.

It's just because the Posacks were so excited.

When Alice briefly described her principles of the "handmade" finished product and the detailed experimental process, Sandy couldn't help but scream. She admitted on the spot that just Alice's remarks had already answered several technical problems for her!

However, even on the way, the couple was so excited that they couldn't help but be excited, and at the same time they were quite depressed.

Isn't it just to see a router? As for being so excited? It's not that Bill Gates went to see the Windows-98 developed by someone else!

“…uh, it seems that’s true.”

Fortunately, it was just after noon, and the traffic flow on the street had not reached its highest peak. After the silver-gray Buick sedan galloped on many main lines, it finally slowly drove into a typical middle-class community.

The houses here are like a house, each house has its own unique shape, and the boulevard is filled with towering street trees. As soon as the Buick car drove in, he couldn't help slowing down when an old man walking his dog came from the opposite side.

"Can I not be excited!?"

Sandy knocked on the steering wheel in the front row, and her voice was loud: "You are only twelve years old, Alice, twelve years old! If that machine really works, let's not talk about the changes it can bring to the computer world, you are really a super genius! You can go to Stanford to study now!"

"The third building in front is the first."

Alice didn't talk to each other anymore, she had already sat softly against the backrest. Oscar was the leader and stopped Buick in front of her yard.

"Mom? Is anyone at home?"

Alice had just walked into the house when she heard a sound from the kitchen: "I brought two guests here, mom!"

As soon as he finished speaking, Sophie walked over from the kitchen, holding a stack of plates in her hand.

"Guest? What kind of guest? Ah... Hello?"

Seeing the hostess appear, Posack immediately stepped forward and smiled: "Hello, Ms. Wang, I am a teacher in the computer department of Stanford University. Leonardo Posack, this is my wife Sandy."

Pointing to his wife, he said, "We met your child in a cafe, Alice said that she made a brand new internet connection device. Is this true?"

Sophie looked at Alice on the left, Oscar on the right, and then at the Posacks who were obviously suffocating, and immediately understood what was going on.

"Oh my God, that's a coincidence. You... met by chance in the city?"

She looked at Alice and answered the couple: "That's right, Alice is indeed developing an instrument. I don't understand computer matters very well, but she has introduced it to me a long time ago. It is indeed a little guy who connects multiple computers!"

After receiving a positive answer, the Posacks were naturally even more excited. Seeing this, since they both entered the house, Alice immediately led them into her bedroom. Fortunately, although she was a girl, she did not have many personal belongings on the surface, so when Posacksack walked in, there was no need to avoid anything.

"Oh, I can tell at a glance that the difference is different."

As soon as he entered the room, Sandy immediately looked at Alice's bedroom happily and said with a smile: "This is such a big bookcase, and it's... The Wealth of the Kingdom? The Complete Works of Sherlock Holmes? The Lord of the Rings Trilogy? Wow, the little genius's hobby is really unique. Do your classmates know it?"

"Several people know. Oscar turned on the computer and helped me get the 'Lisa' done."

After saying a simple sentence, it was like magic, from the corner of the bookcase, Alice suddenly took out an item with a black luster.

Suddenly, except for the busy Oscar, the room was silent.

What appeared in front of the Posacks was a dark metal shell, about the same size as a briefcase, but the weight was not the same.

"First, let me introduce you to the deconstruction."

The two adults were sitting on the bed with a look of surprise, watching Alice sitting on a chair showing her work.

"This is the power supply, the blue interface is connected to the external connector of the network cable, and then these independent network cables are plugged into the yellow interface to connect to the corresponding interface on the computer."

After briefly introducing the peripherals, Alice continued: "It should be noted that these sockets must not be inserted inverted, otherwise they will have no effect. Well, what's the problem?"

Posack looked at the writing desk silently. With the help of Oscar, IBM's computer was placed side by side with Apple's "Lisa", and the machines were also turned on. The DOS operating system and Apple's unique graphical interface were very different.

"Of course there are problems."

Although he said this, Posack's sense of surprise was no longer easy to explain.

Although I was already a little mentally prepared, God, the girl in front of him was really only twelve years old!

How to connect various types of networks, and in the simplest, efficient and low-cost way. Just when the couple, an authentic Stanford teacher, was still having a headache about this and didn’t know how to study it, the Chinese girl made the finished product?

Although the experiment has not been conducted yet, Posack certainly would not think that it was just an empty shell. Even if it was April 1st today, this joke was too unpredictable!

"If you want it to work, you need to rely on software to drive it. Have you written the driver software?"

"Of course, just like this computer requires DOS, my router - yes, I named it a router - also requires an operating system. Of course, the work of perfecting the entire operating system is too complicated. I have just written a basic BIOS and just built a basic system platform."

Posack's eyes lit up suddenly: "Oh my God, what I want to say is just BIOS, an exclusive operating system? This idea is really novel! But if you think about it, you should also make such a system. After all, each network has their own different standards, and you must set it up when connecting. It is not possible to have an exclusive operating system!"

Posack was right, but the facts were far more complicated than this, and Alice knew this very well.

The connection to the network is not just about plugging the network cable.

The most basic point is that the setting of the routing protocol is already complicated enough.

Furthermore, computer software and hardware are made separately by many manufacturers, so there is a compatibility issue here.

In other words, why can other people's products run on your platform?

Of course, this "why" itself is a matter of commercial cooperation, that is, authorization, but after it is implemented in technology, an operating system needs to be used as a medium for detailed programming.

In other words, whether it is a computer or a router, operating system manufacturers need to announce program interfaces to the public, which is the so-called open source. Only in this way can other major software and hardware manufacturers design corresponding products.

Looking at the history of later generations, the most typical and well-known representative of open source is Google's Android system. Correspondingly, the typical closed source is the Apple system, and of course, Linux is even more than that.

The simple verbal introduction has already made the Posacks and his wife unbearable. After Alice briefly said that, she actually connected the line. When she opened a program setting interface lightly, Posack dragged the stool to sit next to her, forgetting how impolite it was to create noise!

The two adults gathered on both sides of the girl, watching each of her operating steps in detail with curiosity and surprise expressions.

Oscar quietly stood in a corner and stared silently at his sister.

"Oscar?"

It happened that at this moment, the door slowly opened, and Sophie walked in with the brewed black tea. Although she liked coffee more, with James setting the first example, the amount of black tea at home was almost equal to the sum of the entire street.

"Oh, mom, I guess they don't have time to drink it for the time being."

With a wry smile, Oscar squeezed his eyes at Sophie: "Three technical weirdos, Alice has found a similar type!"

Sophie looked at the three people at the desk, and their voices kept floating in her ears. Listening to those English words and professional vocabulary that were completely unknown, she couldn't help but shake her head.
