Hong Tao didn't know that Diane was going to Zhou Chuan to borrow, and he didn't pay much attention to this matter, so he basically handed it over to Diane to do. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info can't blame him for being careless, the capital is so big, and there are so many second generations, who would have thought that Diane would get to know Zhou Chuan again, and turn around and turn to the Zhou family.

During this time, he was indeed a little busy, more than 3,000 computers, hundreds of switches, and dozens of routers needed to be installed and networked. Both Diane and Qi Rui have asked him why he didn't pay for a professional to install it.

Hong Tao's answer is: No matter how professional a person is, he doesn't care about himself, and he is afraid to be serious in everything. If the difference in professional skills is not too much, seriousness becomes the key factor.

No matter how professional a person is, he will not wear gloves and treat his computer equipment like a child. Maybe they kicked them as soon as they turned their faces, and they didn't spend that unjust money in vain.

In fact, this is not all true, the reason why Hong Tao is willing to be this coolie is that he does not feel that this is hardship, but a kind of happiness. Whenever I build a LAN with my own hands, install a computer with my own hands, and can feel the details that I haven't noticed or felt before, the physical suffering is really not a problem, and I am very happy.

Diane saw this very accurately, when she first came into contact with Hong Tao, she felt that this man was not a person who planned and did big things. In fact, Hong Tao is not good at mastering the overall character, he prefers to do a specific job with clear goals and detailed procedures.

This may be a common problem of engineering students, who do not have a broad vision and always like to pay attention to details, and are the most suitable deputy, and others will point them to complete.

But now that he has completely fallen over, he has become a person who points the way, so naturally he is not used to it, and even a little resistant. But you can't leave it alone, if you don't have those memories in your head, it's just that, and you don't have any opinions to listen to other people's commands. Now that I know what the future will be, I can't just see that there is a highway and not go to it, so I have to squeeze the national highway with others.

In addition to hobbies, there is another reason why Hong Tao has to pay attention to the procurement and installation of equipment, that is, the increasingly imminent industry competition.

If it is said that the Internet café industry was a profiteering industry in the past few years, from now on, the operating cost of the entire industry will suddenly increase by a large margin, and it has become farther and farther away from the profiteering industry that makes money no matter how it does.

Although it is still a high-profit industry, it has to sell its strength to run well, and the words "losing money" and going out of business will soon appear in the Internet café industry.

The minimum requirement in urban areas is 200 square meters and 100 machines, and in suburban counties, the standard can be lowered by one to 80 computers.

In this way, the scale advantage of Jingcheng Internet café has come to naught, and the hardware is basically on the same starting line as other Internet cafes.

What is efficiency? It is to obtain the maximum benefit with the lowest cost, and specifically to the Internet café industry, it is necessary to make each computer achieve the highest cost performance.

The performance of the computer is too high-end is not suitable for the operation of Internet cafes, because the depreciation of electronic components is too fast, all electronic consumer goods have a characteristic, the price of the new model is particularly high when it first comes out, and it will fall off a cliff in two or three months, and this is the time when it is relatively cost-effective.

Personal use can spend more money for the pursuit of individuality, fashion, and vanity, but as a business operator, you must not chase this trend, on the one hand, you must control the operating costs, on the other hand, you have to take into account customer experience and benefits, and you can adjust these two opposing things to a state of balance, which is the most efficient.

Pentium 4th generation 1.8AGH boxed CPU, ASUS P4B533-845E chipset motherboard, kingston 512MDDR memory, GF4ti4200 64MDDR video memory graphics card, Barracuda 4th generation 7200 to 60G hard disk.

This is the new computer configuration designed by Hong Tao for nearly 30 Internet cafes, none of which are top-of-the-line accessories, nor any of the parts are low-end goods, basically all of them are high-end accessories in the mainstream accessories.

In addition, there is an important indicator is the repair rate, good light performance is useless for Internet cafes, no matter how fast you calculate, it is useless to resist. Whoever uses the computer in the Internet café can not be powered off all year round, coupled with frequent switching, the requirements for electronic components are still very high.

In order to choose the best accessories possible, Hong Tao sacrificed his knowledge on the radio, each batch of accessories must be personally inspected by him, and will only be paid after confirming that they are qualified, and he will refuse to accept them if he is a little dissatisfied, and he will not give a penny. Either you will change it for me according to my standards, or you will take it all back and sell whoever you want, I won't buy it anyway.

Merchants and manufacturers have no problem with him, when you go to the retail market to purchase, the merchant is the uncle, because you don't buy and others buy it, it doesn't matter if you get it once. But if you are directly facing wholesalers and manufacturers in the real wholesale process, then you are the uncle.

Not only do they have to meet your reasonable requirements before collecting the money, but after receiving the money, you can still ask for after-sales service according to the contract, because they are still thinking about your next time.

Who doesn't change the equipment once every three to five years when they open an Internet café? Generally speaking, every two years or so, most of the computer accessories have to be replaced. 3,000 sets, I can't say more but I can't say less, even if I get it to the domestic general representative of INTER, it is worth talking about.

In fact, not every computer accessory can be checked by itself, such as CPU, memory module and hard disk, and individuals cannot check too accurately. So accessories like this will have a one-to-three-year quality guarantee.

Hong Tao talked about the warranty period of three years through Boss Song, that is to say, as long as these equipment are broken within three years, don't talk about what can be repaired or not, and replace it directly. As for what to do after three years, what to do if you love, a computer has earned money for three years and has not been replaced, you let the computer manufacturer drink the northwest wind.

However, accessories such as motherboards, graphics cards, sound cards, network cards, power supplies, and monitors do not have such a long warranty period.

And you can't really believe in the promise of warranty, they are repairing it for you, but a repair is less than ten days and half a month, and more than one or two months. If you can't afford to wait, then buy a new one, anyway, people didn't say they wouldn't fix it for you.

Hong Tao certainly can't afford to wait, and it is impossible to ask the manufacturer to guarantee it for two years or more, so what can be done?

So how can we know that the quality of these electronic products is reliable? Don't look at the advertisement, you have to look at the curative effect. Don't listen to the advertisements in all kinds of publications and on TV, if one of them counts as one, you won't tell the truth. Don't listen to any expert reviews, there are no reliable experts in China, especially in the business field.

Anyone with a radio foundation will know that the quality of an electronic product is nothing more than three aspects, the first is circuit design, the second is the quality of components, and the third is the soldering process.

The circuit design is too professional, not to mention that ordinary people can't understand it, and even people like Hong Tao can't understand it, so you can skip it.

The welding process is too simple, probably look at it without paying too much attention, the manufacturers who cut corners are very thieves, like this at a glance they attach great importance to it, and will do similar to the big factories.

Excluding these two factors, there is only one component quality problem to refer to, in fact, the most common part of cutting corners is precisely in the component. The most representative ones are capacitance, resistance, and inductance.

These three components exist in almost all circuits, and there are still a lot of them, and ordinary people generally only pay attention to the main chip model, but rarely pay attention to the specific quality of a capacitor or resistor, even if you want to pay attention, you have to have relevant knowledge.

First of all, let's talk about capacitors, which mainly play the role of bypass DC, high-frequency filtering, coupling, phase conversion, tuning, etc., according to the dielectric material, it can be divided into three categories: electrolytic capacitors, solid tantalum capacitors and monolith capacitors, each with its own characteristics and functions.

According to the package form, it can be divided into two types: double in-line and SMD, the former is a common cylindrical component on various circuit boards, with two solder legs, commonly known as vertical capacitors. The latter is generally very small, like a rectangle the size of a sesame seed, and is tightly attached to the circuit board.

Specific to the circuit, these two capacitors generally exist at the same time, and they have advantages and disadvantages with each other, and they cannot completely replace each other at present.

There is a saying in the market that the more chip capacitors on computer motherboards and graphics cards, the better the quality, the more advanced tantalum capacitors are than point solution capacitors, and the larger the capacitor capacity, the more stable it is.

This kind of statement is usually concocted by unscrupulous journalists who are less than half a bottle and do not know why. This conclusion is very one-sided, can only be used in some specific circuits, and is not applicable to general household appliances, including computer motherboards, graphics cards and power supplies, and is very easy to mislead ordinary consumers.

You can take a closer look at the computer motherboard next to the CPU socket, there will always be a row of several vertical electrolytic capacitors, a single capacity is usually very large, at least above 1,000 microfarads, some even up to 4,000 microfarads.

If such a large capacity is packaged with tantalum capacitors or chips, not to mention how many times the cost will rise, and the safety will not be guaranteed. The explosion power of such a large tantalum capacitor is greater than that of a bomb, and if you don't get it, you will bang it.

As for the size of the capacitance, it is not cut out in a random pile, it will definitely not be successful if it is small, and it is more troublesome if it is large. The larger the capacitance, the stronger the coiling effect, the greater the high-frequency clutter, and several monolith capacitors have to be connected in parallel for filtering.

If you make the capacitance so large, the filter circuit will have to increase accordingly. The filter circuit is large, and the power supply circuit must also be increased. In the end, your motherboard will be as big as the layup, and once you turn it on, you won't need to consume ten kilowatt-hours of electricity per hour. So you'll have to add a separate water-cooling system to the motherboard, otherwise it will smoke every minute.

Therefore, looking at the quality of a motherboard, just looking at the capacitor model and brand on it, you can basically understand half of it. Don't buy boards with a lot of miscellaneous tantalum capacitors, that's all fooling. Moreover, these tantalum capacitors are likely to be foreign garbage, removed from foreign waste electrical appliances, and used as new ones after polishing, and the stability is even worse.

The electrolytic capacitors used in the regular products of normal first-line manufacturers are usually aluminum electrolytic capacitors of Sanyo, Panasonic, ELNA, and Rubycon ruby series, which have low leakage, high precision and good temperature resistance. Of course, the price will be a little higher than that of miscellaneous capacitors, and you get what you pay for.

The question of how to distinguish these high-quality capacitors was originally very simple, and it was only necessary to look at the parameters and colors of the capacitors. Different colors represent different performance, and some capacitors will have a golden horizontal line in the middle, which is printed with a capital I, which represents low leakage.

The same is true for resistors and inductors, but they are more difficult to distinguish, because they are basically chip packaged, densely packed with a large piece, and it is difficult to distinguish between good and bad quality without equipment and expertise.

However, the Chinese people are too smart, and the counterfeit capacitor products are almost identical, and the engineers of the original Japanese factory cannot distinguish the real from the fake by the naked eye. Just like the real and fake Monkey King, you have to rely on instruments to know their identity. How accurate is the accuracy and the level of leakage, a multimeter is like looking at a demon mirror, and the fake immediately appears in its original form.
