On the evening of the Chinese New Year's Eve, Feng Xiaotian sat in front of the computer, and tonight, he had a very important thing to do, that is, to really connect the computer to the wireless network!

Through these days of study, Feng Xiaotian finally understood his ridiculousness, at first he thought that he only needed to install the radio receiver on the computer, but he failed, at that time he was already vaguely aware of many difficulties in this, but after studying these days, he realized that these difficulties are far more difficult than he imagined!

First of all, the frequencies received by computers and radios are very different, although they are both electromagnetic waves, but if you want to adjust the band of the radio signal receiver to the band of the computer, it is simply an impossible task, because it involves a power problem, to put it in layman's terms, that is, the problem of big feet and small shoes.

How can you wear shoes with big feet and small shoes? If you want to solve this problem, you can only change to a pair of larger shoes, which means that the signal receiver installed on the computer by Feng Xiaotian must be changed to a more powerful one.

Although this question is more difficult, but at least there is hope, Feng Xiaotian After thinking about it, he ran to Lao Li and found a broken "Sanyo", what is Sanyo? It's very simple - this is a larger radio with the function of playing cassette tapes, because the first large radio to enter the domestic market is the product of the Japanese company Sanyo, so all similar things in China are collectively called "Sanyo".

Feng Xiaotian spent a dollar to buy the signal receiver of this large radio, no way, the overall price of this kind of thing is a bit expensive, so even the parts above, it is more expensive to sell, Feng Xiaotian installed this wireless signal receiver on the computer, which solved the problem of big feet and small shoes.

After the adjustment of Feng Xiaotian, the frequency of this receiver has been synchronized with the wireless network signal of the computer, which involves very professional knowledge, Feng Xiaotian spent a lot of effort to finally solve this problem, and there is another advantage of replacing this signal receiver, that is, it does not need the support of the battery, as long as it is connected to the ordinary power supply, it can be used, which saves the money for Feng Xiaotian to buy batteries, and now the battery is five cents a pair, which is still the price of a small battery, The large battery was actually sold for a dollar a pair, which was a relatively unexpected surprise for Feng Xiaotian.

The problem of network signal was solved, but a new problem followed, after Feng Xiaotian installed the large signal receiver on the computer, the computer still displayed a garbled code stream, through Feng Xiaotian's research, he finally found the key to the problem, this problem is more cumbersome, and even more difficult to deal with than the problem of the signal receiver.

The signals emitted by radio waves are extremely complex digital codes, and if you want to convert these numbers into real information, you have to go through a process of information conversion, Feng Xiaotian installs a signal receiver of a large radio, this kind of thing will only convert the digital signal of the radio, as for the information of the computer, it does not have this function at all! Although after the adjustment of Feng Xiaotian, it already has the ability to receive computer wireless network information, but if you want to convert the received digital signal into the content that the computer can display, this is not within its ability, no way, people are not professional.

Since the receiver can't convert information, there's only one way left – to make the computer capable of doing it nher! It sounds simple, but it's extremely difficult to do! Because for a computer to do this, it has to have a translator – yes, a translator!

This is like two people from different countries want to talk, because the language barrier, so each other does not understand what the other is saying, at this time a person who is proficient in the two Chinese languages is needed to translate in the middle, what is the computer translation? The answer is simple – packet conversion software.

All the information received by the computer is transmitted in the form of data packets, so how easy is it to write such a software?

Although Feng Xiaotian is already proficient in computer software, he does not understand the principle of packet transmission, what kind of ability does translation need? At least be familiar with the language of both parties, right?

Feng Xiaotian's problem is this, he knows the language of the computer very well, but he doesn't know what the data package is, in order to solve this problem, Feng Xiaotian even ran to the library in the city center for several days in a row, no way, this problem is too professional, and only large libraries have books on this.

After a few days of study, Feng Xiaotian finally figured out the principle, this problem was finally understood, the only thing left is programming, if you really want to talk about it, this is the most painful, Feng Xiaotian used the knowledge he mastered, using the most common BASIC language, and began a painful programming journey.

For ten days, Feng Xiaotian completely lay on the programming, today is the Chinese New Year's Eve, and it is also the day he is about to complete programming, I saw Feng Xiaotian's hands clicking quickly on the computer keyboard, his eyes are always staring at the computer screen, it seems that he is not worried about fingers making mistakes at all, as time passes, his speed does not decrease at all, when the last character of the program is entered, Feng Xiaotian suddenly reached out and patted the table, and then looked up and smiled: "Ha Lu Ha!" It's finally done! ”

Feng Xiaotian is like a child, constantly jumping around in the house, looking extremely funny, at this moment his heart has already been filled with joy, in his opinion, the happiest thing in life is to put his ideas into practice, that feeling of success, is not experienced by others, and only Feng Xiaotian will be like this, because he has no worries, only the exploration of new areas, is the meaning of his life.

Feng Xiaotian was excited for a long time, then calmed down, he rubbed his fingers that were already sore, and sat down in front of the computer again, since the program has been written, the next step is to go through debugging, to see if there are any grammatical errors in it, soon, Feng Xiaotian will be debugged, there is no problem with this software, Feng Xiaotian embedded the program into the computer operating system, and then activated the software, and then the software ran on the computer.

As the interface continued to change, the computer finally showed a prompt that the signal reception was normal, and then Feng Xiaotian began his novel journey, but soon, he stopped, because he was connected to the domestic network, and there was only a small range of local area network in China at this time, and there was no Internet recorded in computer books at all.

Feng Xiaotian was disappointed, this was not the result he wanted, what he wanted was to be able to roam freely in the ocean of the Internet, what is the difference between being like this and being trapped in a small pond?
