When the programmer opens the plug-in

Chapter 105 Flying Internet Speed

After watching an introduction on the virtual screen, Cheng Wen realized how amazing this thing really is.

Like memory, Cheng Wen can separate this and decide what device to add.

No matter what the original operator is, they can increase the network speed on this device by 20G on the original basis.

It can even break through the blockade of some complex networks.

And unlike the current castrated home network, the uplink and downlink rates are the same.

Ordinary people have no idea about this, but everyone can understand it by using the network disk as an example. Usually, when people watch movies and videos, they mainly pull things from the server, that is, they use the downlink bandwidth.

But the network disk sometimes needs to send a large amount of data to the server, such as saving your own photos or some files.

At this time, the uplink bandwidth is used.

In fact, there is a calculation formula. If your home network is 200M, the maximum download speed is 200/8=25MB.

The unit of the communication industry is a small b, and our ordinary people pay attention to B, which is 8 times worse.

而上传的速度是最大下载速度的1/8，也就是25/8约等于3兆。

Cheng Wen didn't understand what kind of black technology the system used to achieve this speed, but it didn't affect Cheng Wen's use.

With this, even if a Baidu network disk is installed and it silently activates the user incentive plan, it will not have any impact on Cheng Wen, as long as he does not fill up the upstream bandwidth.

Just when Cheng Wen was thinking about the usefulness of this, he didn't think of this network attribute, and the time came for the first time to use its ability.

Before Cheng Wen went to the south to deliver a tob project.

Now they want to upgrade their data, and they use their own school's intranet.

In such a situation, there are usually three solutions.

The first method is for the engineer to fly over and carry a mobile hard disk to operate on the spot. However, this cost is too high and is rarely used. However, this is also the safest method. As long as the engineer lands, generally there will be no problems.

The second method is that the engineer is still in his own company and opens a software that can be used remotely, such as Sunflower, TeamViewer, or if it is Windows, QQ remote assistance can also be used. This is convenient, but its biggest disadvantage is that it is affected by The influence of the Internet is too great.

People who get stuck often feel like dying. Things that should be done in 1 minute may not be connected to the other party's machine after 10 minutes.

There is also a third method, the engineer is still in his own company, but he needs a vpn from the school, open the vpn software, enter the account password, and then he can connect to the other party's intranet, but this is rarely given, after all They are just third-party companies and supporters, not teachers and students of the school.

Another method is that they forward the ports of those servers on the intranet.

In this way, engineers can connect to that machine by connecting to a public network ip, but a machine with a public network ip is required, which is more troublesome for people who cannot operate, and there is no other convenient method.

The back-end classmate Du Wenguang adopted the simplest method this time. The second method is to ask the other party to open a sunflower, and they can connect it to operate.

Usually, the network of Du Wenguang's home is still very smooth. When downloading a movie or something, the fastest time may be to download 10M data per second.

But today, Du Wenguang has doubts about the home network during use. Is this really the network that can download at 10M per second?

Why is it so hard?
Later, he had to ask everyone in the group for help, asking who had a better network, who could help him pass some files and execute some orders.

The other backends in the group also tried it, but it was also very stuck, and they couldn’t even connect at all. Sometimes they connected, but they quit after no operation. Everyone agreed that this was a problem with the other party’s network.

In fact, there is no problem in making this conclusion. The other party's network situation is indeed very complicated.

Cheng Wen also tried, he added the network attributes to his computer.

It was found that it was connected in an instant, and the operation was smoother than when he usually operated his own computer in the company.

"Is it not a problem with the other party's network, but a problem with yourself?"

Cheng Wen thought so, and then he deleted this attribute, and found that it was very difficult to connect to it, as they said in the group.

Add this attribute again, and it will be better in an instant.

It was only then that Cheng Wen remembered that there was a paragraph in the system description that this network could break through the blockade of some complex networks.

Cheng Wen didn't know what this breakthrough meant, but he felt that the current speed must be related to this attribute.

[I can still connect here, but there is a bit of a card]

Cheng Wen sent a message in the group.

[That's great, I'll send you the file, can you help me operate it? 】

When Du Wenguang was worrying, he didn't expect Cheng Wen to be able to connect. It's not like he hasn't seen slow ones, but it's rare to see ones as slow as this time. After all, he didn't connect for more than ten minutes this time.

【no problem】

Then the two chatted privately, and Du Wenguang sent Cheng Wen the things that needed to be uploaded. They were on the public network and did not involve the internal network, and the speed was still very fast.

Cheng Wen received the file, and according to what Du Wenguang said, sent the file to a certain address.

Then some commands were executed, and the operation was quickly completed.

When Cheng Wen finished, he realized that he was remotely operating someone else's computer, not his own.

He completely forgot about it when he was operating just now.

In the future, I will never encounter a network card again, and Cheng Wen is still very happy with this reward.

There are too many places where they need the Internet at ordinary times.

Someone asked a question on Zhihu before - what are the factors that most affect work efficiency in the company?

Some people said it was the sound of the decoration next door to the company, some said it was interrupted by someone, and some said it was the company's network...

Later, I found out that there were a lot of people voting for the Internet, and some companies obviously made a lot of money, but they just couldn't bear to update their company's network and replace it with a more efficient network.

Many things that can be done in one minute are dragged to two or three minutes. If it is only one minute, people can still devote their energy to this work, but for several minutes, people can't wait all the time. this matter.

The result is that they will use this free time to do some other things, some have other jobs, and some simply read the news or something.

When they come to their senses, it often takes more time.

Even people who are dealing with other work will spend more time, because he has to interrupt the current work back and forth, and sometimes it takes a long time for an interruption to re-enter the state.

On Cheng Wen's last day at work, he didn't have any other special things, just helping to find bugs or something.

I submitted a resignation application on the company's platform. In fact, I had to apply one month in advance. However, although Yao Shao didn't want Cheng Wen to leave, he had to say that Cheng Wen's work was very good and the documents were well written. There is no need to resign and handover at all.

When developing together with Feng Le, the two would think of studying each other's code, but most of the time Feng Le was studying Cheng Wen's code.

He learned a lot from Cheng Wen's code.

At the moment when he finally got off work, Cheng Wen felt that he was a free body, and felt unprecedentedly comfortable.
