Chapter 986

After school that day, the students of this class all looked pale and floated out with dull eyes.

After suffering for six years, I thought I could finally see the light, but I found that I was greeted by a deeper darkness.

Think about the next four years, people want to cry without tears.

At the beginning, students of other classes wondered how these seniors had been so happy recently that they suddenly looked like they were worse off than dead.

When they knew the situation, they also changed their faces one by one.

The future of these seniors is their future

Life is better than death. Naturally, some people are happy.

Zhan Caixian, for example, likes it very much.

With teachers, the students are also interesting. They can learn all kinds of interesting things and go to the library to see interesting comics.

She doesn't like to work in any department, and she doesn't lack money at home. It's best to keep learning in this university!

Ten days later, the first students graduated again, but the graduation party was much simpler.

This time, all the students in civilian families chose to graduate except one.

After all, it is enough for them and their families to learn what they are now. It's too much pressure for them to study for another four years. After all, the family situation of ordinary people can't support them to learn like this all the time.

They don't want to.

Now Dayao is changing. Lancheng and Dayao are different every month. When they are in the University, they watch all this and often have the idea of participating.

Therefore, they chose to graduate and enter six departments.

Ren 8000 also understands this.

As for the descendants of those powerful families, none of them graduated successfully.

They all went to college.

In a howl, the first thing to greet them is the entrance examination a month later.

……

At this time, the eyes of a group of people were on a small table in the center.

On the table is a black box with a disc with numbers 0 to 9 written on it.

There is a thread on the box, which is connected to the outside of the hall.

Ren Bayi held the microphone on the box in one hand and turned the disc in the other. A moment later, a beep came from the microphone.

There was only one sound and the other end was picked up.

"Your Highness?"

"We succeeded!" Ren 8000 looked at the crowd and smiled.

There was no response, and the other end of the phone cheered.

Ren 8000 said a few words of encouragement to the other end of the phone, then hung up the phone and looked at the people in the hall with a smile.

"Your Highness, isn't this the same as the previous radio station?" Shi Qing asked.

Although Ren 8000 didn't explain, they had guessed the purpose of the box.

"No, radio is a radio. Radio is a kind of fixed frequency communication in which we talk in one channel after another. There are several disadvantages. First, the number of fixed frequencies is limited, and radio stations can't be used by everyone.

Second, if others get a radio station, they can hear the conversation on the channel.

Although this has not happened before, it does not mean that it will not happen in the future.

Third, the anti-interference ability of radio stations is weak. For example, in the place of sky scenery, radio stations cannot be used. "

People do not understand technology, nor do they understand the meaning of Ren 8000 words.

Just from Ren 8000's words, we can hear that this box is a better thing than radio.

"Let me introduce you." The female emperor sat on the head and said faintly.

"Yes!" Ren 8000 gave the empress a smile.

He turned around and said, "this is a telephone, which is also used for long-distance communication with radio stations.

There is no need to say anything else, just two points. First, this is point-to-point communication. A phone can communicate with any phone by dialing the corresponding number.

For example, this one can make point-to-point calls with any department of the six departments or any department in any city at any time. Only people at both ends of the phone can hear everything. "

The crowd nodded, and this time they understood.

The radio station is for everyone to chat together, and this phone call is for two people to chat in private.

"Second, the most important thing is the popularity of telephones. Telephones can be laid anywhere in Dayao, with millions or tens of millions of telephones.

Whether it is all departments, all cities, or even every family.

Everyone can use a phone to dial the corresponding number to talk to one of the millions of phones.

For example, Lord Shi can install such a telephone in his house.

As long as I have the corresponding number of the telephone in Mr. Shi's family, I can call Mr. Shi's house from any place through any telephone at any time to talk to Mr. Shi.

For example, if you are in any corner of Lancheng, or in any corner of Dayao, even in 60000 mountains, you can also contact your family by telephone. "

When Ren 8000 finished speaking, he looked at the people with a smile.

We have to wait for them to react.

Although they have seen enough new things over the years, they still need some time to digest Ren 8000 words.

On earth, the early application of telephone was a magnet telephone, that is, the kind in the film that makes a phone while generating electricity by hand, and then transferred through the operator.

Then there is the common telephone, which no longer needs to generate electricity by hand, but it still needs the telephone operator of the Telephone Bureau to connect manually.

This kind of telephone needs to be transferred manually, so there are few numbers, and the number of natural users is impossible.

At the beginning, the largest modu telephone office in Asia had only a few thousand users.

The biggest limitation on telephone is not the technology of telephone, but the technology of telephone interaction.

The above two types are connected manually, and then the step-by-step switch can connect the telephone through the mechanical mode. However, there are many disadvantages, especially large loss and difficult maintenance.

Knowing that this kind of thing will enter thousands of households sooner or later, Ren 8000 naturally lost this kind of pass directly.

He used the more mature crossbar switch technology.

In the fifties and sixties of the earth, the use of this switch has become the mainstream.

In China, it has been used in the 1980s and 1990s.

Of course, this is also a technology that will be eliminated sooner or later.

However, what the next generation of technology needs is electronic technology.

Ren 8000 waited for a long time before people began to move their faces gradually.

"Eh?"

"Your Highness means that this thing can be put in our house?"

"Not only your family, but everyone's home, even those stockaded villages on the mountain!"

Ren 8000 corrects the right way.

Of course, there is a premise. First drive away the birds and beasts that have nothing to do with pulling wires!

The cities are fine. There are many fierce beasts in the wild who like to pull wires or dig holes.

"Eh --?"

The crowd immediately exclaimed.

Everyone has such a phone in their home?
