Lin Hong still has a good understanding of the current international wireless LAN communication, basically mainly infrared wireless, and the protocol used is still based on his protocol. Pen, fun, and www.biquge.info

As far as he knows, an organization called the IEEE802 Standardization Committee has set up a standards working group and is working on a standard, which is also called Wi-Fi.

However, in Lin Hong's view, this so-called standard protocol is also inseparable from the infrared wireless protocol he specified before, and the principle is essentially similar, and the speed is not much faster.

And the wireless vortex information transmission he is now envisioning is likely to increase the transmission rate by at least ten or even a hundred times on the original basis!

Lin Hong has no bottom in his heart now, he only has a vague idea for the time being, and he must further study and improve the relevant theory.

Lin Hong was thinking about distorting and modulating these signals and what technical operations were needed when the bell rang for the end of class.

"That's all for today." The old master did not have the habit of dragging the hall, and when he heard the bell ringing, he immediately ended the explanation.

When he reached the door, he suddenly paused, turned around and said, "That...... New students, come to my office. ”

With that, he left the classroom. The old master saw Lin Hong for the first time, and he didn't know his name yet.

When he left, the whole class suddenly became lively.

"Lin Jiang, are you still here? The old master asked you to go. ”

Lu Lei saw that Lin Hong was still sitting on the role of a man holding his chin motionless, and couldn't help but kindly remind.

"Huh? What's up? Only then did Lin Hong come back to his senses from thinking.

"How do I know what's going on? Maybe it's because of the finale, you'd better hurry over, he doesn't like people being late the most, and he's still a hot temper. ”

Then Lin Hong asked Lu Lei about the general situation of the old master, and after thanking him, Lin Hong came to the old master's office.

"Here we go." The old master was waiting for his arrival, "Your name is Lin Jiang?" Is it a relative of Teacher Feng? ”

He had just learned a little about Lin Hong's situation from the head teacher of class 287.

"Yes." Lin Hong nodded.

"You have a good foundation in mathematics, where did you study before?"

"In Province J."

Lin Hong answered truthfully according to the information on his file, his new identity, in order to be able to cope with the investigation of some interested people, is also more reasonable, and ordinary people really can't find out anything.

The old master didn't care about this, and then said, "Have you done these two questions before?" ”

Lin Hong realized at this time that the old master called him because he had solved the problem too smoothly and attracted his attention.

However, Lin Hong didn't plan to hide anything this time, he had already made up his mind to be admitted to Mizuki University, so he said, "No." This is the first time I've seen this type of question. ”

"Oh?" The old master's eyes lit up.

He thought for a moment, took out a test paper from the drawer, and then pointed to the last two questions and said, "Look at these two questions, will you do them?" ”

Lin Hong took the test paper, looked at it for a while, then picked up a pen on the table and answered it in a few clicks.

The old master took it and looked at it for a while, and then praised: "The idea of solving the problem is exquisite and concise, wonderful!" ”

The method used by Lin Hong is once again very concise, omitting many steps in between, which can only be done by those who are very familiar with mathematics and know it well.

The old master looked at Lin Hong and nodded with a smile: "Not bad!" However, I still want to remind you that although this kind of solution is usually correct, there is still a risk of deducting points in the college entrance examination. You should write out the reasoning steps implicit in between......"

The old master took the pen, added a few steps in the middle, and then let Lin Hong take a look.

Lin Hong nodded, indicating understanding. These steps seemed obvious to him, but since the exam required it, it was okay to write more Braille.

Then the old master asked him to do a few more questions, this time Lin Hong's problem-solving process was decent, and the old master nodded again and again.

The old master regretted in his heart that Lin Hong hadn't turned around earlier, and the more he looked at Lin Hong, the more satisfied he became.

"Here are the test papers of several mock exams from the last semester, you can take it back and do it well, if you have any questions, you can always come and ask me." The old master took out another stack of test papers and handed them to Lin Hong.

After Lin Hong thanked him, he left.

"Hehe, it seems that the first student in mathematics this time will appear in my class again!" The old master looked at Lin Hong's back and smiled.

He felt very aggrieved for a whole year, because in the two classes he taught, none of the students in mathematics belonged to the outstanding type, and the highest score in every math test was not in his class, knowing that in previous years, the highest score in math exams came from his class, which made him feel very regretful. Although he has found several promising seedlings for key training, they are diligent enough, but unfortunately they lack some talent, as long as the difficulty of the test questions is raised, they will be thrown out by others.

And now, in the last month or so, I didn't expect to transfer a student with a very good mathematical talent, which couldn't help but make the old master a little happy, and his undefeated brilliant record will continue to be maintained

Lin Hong naturally didn't know that he had been included in the old master's key training plan, so he returned to his seat with the test paper, and then began to answer.

He also realized that his problem-solving habits might not be suitable for the current examination system, and although he felt bored, he had to adapt to these rules, otherwise he would definitely not be able to get a high score and be admitted to Mizuki University.

Each field has its own rules, and if you can't be a rule-maker or game-changer in that field, you have to follow those rules if you want to be successful in that field.

Lin Hong's speed of solving the problem is amazing, basically he did not alter it, and he did it all the way directly, not even the manuscript paper. He started these tests as if he was doing the oral arithmetic test questions of a primary school student, and he passed all the way without any pause.

After finishing a test paper, he didn't bother to put pen to paper anymore, he directly picked up other test papers and scanned them quickly, and only took a moment to think about them when he saw different types of test questions, otherwise he would skip it directly and no longer waste extra time on it.

I have to say that mathematics is Lin Hong's strength, and Lin Hong has no problem coping with the college entrance examination in this subject, mainly he pays attention to the steps of solving the questions, and believes that it is completely possible to get a full score.

Lin Hong was not familiar with the situation at the school at first, so most of the time, he was observing and rarely communicating with others. The one who talked to him the most was Lu Lei, who was separated from him by a corridor. But this guy is a talker, and once he opens the conversation, he will talk non-stop. When Lin Hong was usually fine, he was absolutely unwilling to take the initiative to provoke him.

When receiving the textbook, Lin Hong also received a student recharge meal card, the principle is similar to those cards in the public phone booth, there is an IC chip that can store data, and it can be simply read and written through the card reader, so as to increase and decrease the value.

After the third class, Lin Hong followed the tide of other students and walked towards the school cafeteria.

The cafeteria was at the very bottom of the school, just above the building where he had been to the Academic Affairs Office, and it was a long walk.

Lin Hong noticed that as soon as class ended, many people ran towards the cafeteria at a speed of almost 100 meters, and at first he was very curious about this phenomenon, guessing the reason why they were so positive. Later he learned that they were trying to be at the front of the queue so that they wouldn't waste precious time.

After lunch, Lin Hong wandered around the campus, and when he came to the basketball court, he didn't expect to see an acquaintance in the cement audience.

It was only after repeated confirmation that he finally determined that this person was someone he knew. Lin Hong hesitated, thought twice, and walked over to say hello to the other party.

"Chubby."

A fat man with a figure of about one meter six or five, but his whole body was extremely fat, and he was stunned when he heard this.

Nowadays, few people call themselves that, and everyone usually calls themselves "big fat".

He turned his head to look at the other party, and found that he didn't know him, so he couldn't help but wonder, "Who are you?" ”

Compared with before, Lin Hong has changed very much, and it is like two people, who are not close relatives, and they can't recognize him at a glance.

Lin Hong smiled: "I'm your old friend, I used to play Apple game consoles together, did you forget?" Your arcade is not open? ”

Pan Pan was completely stunned, and after a while, he asked in a low voice with some uncertainty, "Are you Lin Hong?" ”

Lin Hong nodded and sat down beside him.

"I changed my name, and my current name is Lin Jiang, and I just transferred to No. 1 Middle School, but I didn't expect you to study here."

"I'm grass, isn't it, it's really you?" Pan Pan's body was stunned, and the fat all over his body trembled and vibrate.

"Of course it's me. Wuzi also mentioned you to me a few days ago, saying that you are fatter than before, but I didn't expect it to become like this, your body type, it's time to lose weight. Lin Hong held the fat on his stomach and shook it twice.

Pan Pan heard this, where is the slightest suspicion? directly hugged Lin Hong and hugged him a few times.

Although Pan Pan has no connection with Lin Hong, he has intermittent contact with Sun Wu, and the two play games together, drink, and talk about the most topics, but Lin Hong is still the most talked. Although they have only been together for a short time, they have a feeling that they have known each other for a long time.
