In the end, Wu Dong was persuaded, he decided to buy a computer, to invest in his future, he believed, as long as he worked hard enough, he would definitely be able to do what Lin Hong said, for his future self, the money of a computer is not very much at all. Pen, fun, pavilion www. biquge。 info

Zhang Da said happily: "Then it's decided, we will go to the computer market tomorrow to buy a computer!" ”

Other people are even happier with computers than with their own computers.

Wu Dong: "What brand of computer should you buy?" What configuration? ”

Zhang Dadao: "I personally recommend Lenovo. After all, it is a big domestic brand, and the price is also very affordable. ”

Li Qi has no opinion on this, he will buy whatever Wu Dong wants.

However, Lin Hong has a different opinion: "If you want to quickly get familiar with the computer, I don't recommend buying a brand new computer." Buy a second-hand one, the brand is not important, the configuration is not important, as long as it can be used. ”

Zhang Da couldn't help but be surprised when he heard this: "Second-hand? ”

"Hmm." Lin Hong nodded, "You two both buy second-hand ones, now the hardware is updated quickly, maybe this month's advanced configuration will be behind next month." Moreover, you are beginners, it is useless to pursue configuration, the most important thing at present is to learn the relevant knowledge of computers, and second-hand computers can fully meet your requirements, and can allow you to master the relevant knowledge faster. ”

Although Wu Dong and Li Qi didn't know why second-hand computers could make them master computer knowledge faster, they still chose to follow Lin Hong's advice and choose second-hand computers.

At Lin Hong's suggestion, Zhang Da helped post a purchase post in the flea market section of Shuimu BBS, asking for second-hand desktops, if there is no complete machine, accessories are fine.

Soon, several senior brothers replied to the post. Said that there are accessories left over from their previous upgrading.

Three days later, Wu Dong and Li Qi both had their own computers. The configuration is not high though. It's been a few years, but it's still working, and it's cheap, only about a fifth the price of a brand new computer with the same configuration. Of course. This is mainly due to the fact that many senior brothers don't care about such a small amount of money, so they simply sell it half and give it away.

Wu Dong and Li Qi's computers are not complete machines. It's all a compatible machine that has been assembled under a patchwork of things.

In the process of assembly, they have a deeper understanding of the hardware of the computer.

This assembly process was carried out with the assistance of Lin Hong, who assembled it over and over again. While explaining to them what the accessories in their hands are. What is the role.

Although they know from the basic textbooks that there are such things as the basic components of computers, books are books after all, and after reading them once, they don't feel anything at all.

Zhang Da didn't do much research on this before, because he bought brand machines before this, and brand machines were not allowed to be disassembled by themselves. Once dismantled, it loses its warranty eligibility. So, although he has been playing with computers for two or three years. But the case was never opened to see what's inside.

This time I assembled the computer, and only then did I have a more vivid and intuitive understanding of the basic components of the computer.

For the first time, they knew that the memory module was really a small long strip, which could be directly plugged and unplugged, and the CPU was so small, so expensive, and so many pins. There is such a socket on the computer motherboard, and it is a foolproof design, so there is no risk of plugging it in reverse.

After Wu Dong and Li Qi had their own computers, they were really excited for a while, and as long as they had time, they almost stayed in front of their computers and sat down, either surfing the Internet or learning basic computer commands.

After a few days of tinkering with Li Qi, the interest went down, he didn't move much after he pretended to be one, and what he did every day with the computer was to log in to Mizuki BBS, and brag to the people on the forum, and soon mixed up with the position of a moderator, and after meeting with the management of the forum offline, he was very familiar with the person in charge of BBS, and gradually became one of the main managers of Mizuki BBS, specifically responsible for organizing activities.

Wu Dong, on the other hand, is a restless person.

Since it was a second-hand computer, it was carried out at first

His computer configuration is a little lower than Richie's, but he doesn't want to install it and finish it, he knows that Microsoft has a new system last year, called windows95, and Zhang Da just has the installation disk of this system in his hand.

Wu Dong pondered about upgrading his system. Recently, he has been running the reading room of the school library every day to read some magazines such as "Computer Newspaper" and "Computer Enthusiast", and he has also seen an article on how to upgrade.

So, he copied the upgrade steps of the article, and then ran to the dormitory, strictly following this step for Henderson. After some tossing, he actually succeeded. Although because the configuration is relatively low, there are a lot of special new ones that are not available on the operation, and the interface is also much better.

However, Wu Dong soon discovered a serious problem, that is, there was no sound in his computer speakers, and he could not play music.

How so?

Wu Dong felt very strange, he went to the library several times but couldn't find the specific reason.

There was no way, he had to ask the boss. The boss has been at school all this time, and like him, he runs to the library every day, which is easy to find.

When Lin Hong heard his words, he said: "There is a lack of sound card driver." ”

Sound card driver?

Wu Dong was a little impressed by this term, as if he had read it in that article.

Seeing that Lin Hong seemed to be busy, he didn't continue to bother him, but found the article he had seen before from memory.

It is an article dedicated to the driver of computer accessories, explaining in detail what a driver is and why you should install it.

Wu Dong read this article before, and at that time he saw it as if it was true, and felt that it seemed to be like that, but he didn't understand it.

This time. He encountered such a problem himself, and it suddenly dawned on him. It turns out that the drive mentioned in the article is like this!

We are in life. The brain will automatically process this information, and the things that you are familiar with and understand are generally more impressive, but not the things you don't understand. Often, it's just a passing impression, with only a vague impression.

Wu Dong read this article before. Although I saw the article that introduced the driver, I seemed to understand it at the time, but I had never been exposed to it. Not impressed at all. In the blink of an eye, it was almost forgotten.

And when he encountered the fact that the computer could not make a sound, it dawned on him that the article was about this! Since then, he has a thorough understanding of the driver, and he no longer knows it when he encounters it, as he used to be.

Follow the content of that article. Wu Dong copied a few drive files from Zhang Da's computer and put them on his computer, and restarted them. Sound can finally be heard in the speakers.

Because his computer is running windows95 too slowly, it takes half a day to open a software every time, and after his novelty has passed, he can no longer stand this state, so he plans to uninstall the system and return to the original system.

But how do you uninstall this system?

This was another problem, and he went to the library to look up materials, and after looking through a lot of computer magazines, he finally found an article.

So he followed the article, went to the boot disk, and formatted the original system.

What he didn't expect was that this formatting would cause a problem, and he would no longer be able to install the system because his software was faulty and he couldn't recognize the floppy disk inside.

What can I do? If you can't recognize floppy disks, won't you be able to install the system?

Wu Dong's computer is relatively old-fashioned, there is no such thing as an optical drive, and the only device for exchanging data with the outside world is a floppy drive, which can use a floppy disk for system installation and file transfer.

And now, the floppy drive is useless, and the system cannot be installed.

Wu Dong was in a hurry, so he had to ask Lin Hong.

Lin Hong checked his software and found that it couldn't be used at all, the software had reached its service life, and there was no point in repairing it.

Lin Hong gave him several solutions.

Either go and buy a new floppy drive and install it, or directly remove the software on Zhang Da or Li Qi's computer to make do with it, and after the installation is completed, uninstall it again.

In addition to that, there is a solution and that is to use USB. After all, at this time, the interface of the USB flash drive has become the standard configuration of mainstream computers, and the use of the USB flash drive has also become popular.

Replacing floppy disks with U disks is a good solution, and Wu Dong prefers this.

However, he took a look at the back of his case and found that although the design of the case reserved holes for expansion cards, there was no USB port.

Could it be that because it was a previous computer, there was no such interface?

At this time, Lin Hong told him that the standard of the U disk had actually come out a long time ago, and the manufacturer should have reserved such a plug when designing.

Lin Hong will take the computer apart, and sure enough, he saw a few lead pins on the motherboard.

"This is the USB data pin, find the extension cable and plug it into it, you can use it, but here you have to short-connect......"

According to Lin Hong's method, he took an extension cable out, and then connected it to the U disk, and selected the order of starting the device as starting from the U disk, and sure enough, he entered the boot system interface.

They had to admire Lin Hong's erudition, and even knew this kind of thing.

Later, Wu Dong's second-hand computer kept having various problems, and in order to solve these strange problems, Wu Dong had to consult various materials to find out why such problems occurred.

Unconsciously, Wu Dong gradually transformed from a rookie to a master of computer maintenance, no matter who has any strange phenomena on the computer in the class, he only needs to know what the problem is at a glance. For example, if the computer suddenly fails to boot and an alarm is issued, he will know whether the memory is not plugged in properly or it is faulty.

In the past, he was a rookie who didn't know anything about computers, but now, when everyone's computer has a problem, they like to ask him to solve it.

It was only at this time that he understood why Lin Hong advocated that they buy a dilapidated second-hand computer first, if it was like Zhang Da, directly buy a brand machine, and then don't care about anything, and send it directly to the official maintenance site for repair if there is a problem, then he can't touch the hardware inside at all, and he can't encounter all kinds of strange software problems, so he naturally doesn't have to consult information or ask others in order to solve these problems, and his computer technology will not be able to improve.
