Chapter 133 Super Magic Machine

Vina came back so early today. On the one hand, she tidyed up the lawn at home, and on the other hand, considering that Lin Honggang came here and there were still many things to buy, she planned to take him to the supermarket for a big purchase today.

So, as soon as Lin Hong returned to his room, Vina called him down.

Although Lin Hong really wants to finish the three books at this moment, he really needs to go to the store to buy something. Anyway, it will take a long time, and he is not in a hurry.

The town is a short distance from the city center, so you need to drive there.

As long as there are a little people in China, there will inevitably be all kinds of small shops, but this is not the case here.

In the residential area, you rarely see shops, bars, etc. If you need to buy something, you must drive far away to buy, and you will buy a lot of things at one time, and then store them all in the warehouse or refrigerator.

Vina took Lin Hong and Arthur to a supermarket in the city center.

Supermarket is a relatively new thing for Lin Hong.

Although he also went to the department store with his mother when he was in Beijing, he had never seen a supermarket. He is very curious about these things. If there is anything he doesn't understand, he casually asks Vina.

Not long after arriving here, Lin Hong's character began to change slowly. He spoke much more times than when he was in China. This was the subtle influence of the surrounding environment on him. For the time being, he did not realize this.

When Lin Hong first came to the United States, when he looked at the prices of things, he often converted these prices into RMB according to the exchange rate, and then compared the prices of the two.

He found that the prices here are sometimes very expensive. Some snacks are often nearly ten dollars, but some electrical appliances are quite cheap compared to China.

The supermarket was full of things and everything. After Vina arrived here, she asked Lin Hong and Arthur to push a big car to follow behind her, and then she began to shop crazily, moving everything box by box.

At Vina's suggestion, Lin Hong also bought something, mainly school supplies, such as pencils and paper. Because American middle school students usually don't use ballpoint pens or pens at all, and the school stipulates that they must use pencils.

In addition, Lin Hong also bought an electronic calculator model TI-82. This is a scientific calculator specially designed for students. Arthur said that it will be used in many exams in the future.

Lin Hong has never seen this product since he was a child. He took a look at the instruction manual of this product and was deeply shaken by its function and configuration. This product is produced by Texas Instruments. It can not only perform multiplication, opening, index, logarithm, trigonometric function, statistics and other operations, but also includes powerful functions such as function charting, polar coordinate mapping, parameter mapping, sequence mapping, statistical analysis, triangular and algebraic functions.

Lin Hong was stunned when he saw his configuration list. He muttered in his heart, "This is completely a computer!"

It's not his fault. The configuration of this calculator is a little unbelievable. The CPU is Z80, with a frequency of 6Mhz and a memory of 32KB. In addition, there is a flash memory that can be used to store data, with a size of 512KB. Through the data cable provided by the manufacturer, this calculator can be connected to the computer to exchange data. In addition, this calculator There is also a built-in infrared sensor, and the calculators can wirelessly exchange and collect data with each other, and the speed can reach 9.6K bits per second.

Lin Hong just took a rough look and felt that this thing was too powerful. In his opinion, it was completely a computer. THIS CONFIGURATION IS STRONGR THAN HIS APPLE-II.

Is the hardware configuration of the calculator so high in the United States? Lin Hong couldn't help sighing.

He asked the price, one hundred dollars.

After a calculation in his heart, it was about 470 yuan. Lin Hong gritted his teeth and finally bought it. According to Arthur, this thing is basically a necessity for every student, one for everyone.

In addition, after Lin Hong bought another pair of trousers and a pair of shoes, he went home with Vina.

Originally, Vina wanted to pay for Lin Hong, but he gently refused. The other party was good enough for him. He couldn't be ignorant and took an inch.

※※※※※

After dinner, Arthur took the initiative to invite Lin Hong to his room.

Arthur's room is next door to Lin Hong. The size and layout are similar, but the layout and furnishings inside seem to be a little different.

The walls are covered with all kinds of posters, most of which are Bruce Lee's, and there are also all kinds of sports equipment, such as basketball, tennis rackets, dumbbells, skates...

On the other side of the balcony, there is even a hanging sandbag. After Lin Hong tried it later, he found that it was not sand, but it was quite heavy to hit.

There is a desk next to his bed with a very new computer. Lin Hong took a look and found that the brand is also Apple's, but it is not the APPLE-II he saw, nor is it its upgraded version of APPLE-IIe.

Out of curiosity, Lin Hong asked. It turned out that this computer was a dell'at-McInta computer that was only listed by Apple in March last year, and the model was MAC-IIfx.

The machine in Lin Hong's room was used by Arthur before. After Christmas this year, Arthur borrowed a sum of money from his parents, and then added his previous savings to successfully move the Mac-IIfx home. He has been interested in this computer for a long time, and it took nearly a year to get it.

As soon as Lin Hong asked about the configuration of this machine, he almost drooled.

The CPU is Motorola's MC68030. Lin Hong has no idea about this, but when he heard that the processing speed of the chip reached 40Mhz, he was completely shocked.

40Mhz, what kind of concept is this? THIS SPEED IS 40 TIMES THAT OF HIS APPLE-II! His computer in Beijing was only a poor 1Mhz. At that time, Lin Hong thought it was very good, but he didn't expect that Arthur had used this speed. I really don't know. It's a one-to-one jump.

"How much memory is there?" Lin Hong swallowed his saliva and continued to ask.

"The standard configuration is 64MB, but I have upgraded it to a maximum supported capacity of 128MB." Arthur said proudly.

This machine has cost him several years of pocket money. In addition, he also wants his parents to borrow a huge sum of money, and he doesn't know when he can pay it off. For the past few months, he has been thinking about how to make money to pay off debts.

Lin Hong: "..."

128MB?? He almost doubted whether he had hallucinations.

After confirming it again, he finally had to accept this fact. Although he was mentally prepared enough, he was still shocked by this data.

God, has the computer developed to this stage?

Lin Hong has the illusion that he seems to be still in the Stone Age, while Arthur has already entered the industrial era.

What is the concept of 128MB?

You know, the memory of his machine is only poor 4KB.

1MB=1024KB!

That is to say, the memory of this machine is 32768 times that of his!

"Damn it!" Lin Hong couldn't help swearing.

What is an artifact? That's it! His one is simply the ore radio in the radio!

Arthur looked back at him doubtfully. He couldn't understand what this meant.

Lin Hong was afraid that he would misunderstand and quickly praised his computer's configuration. He never thought that such a high-configuration computer had appeared in the United States.

In this regard, Arthur felt very ordinary. He told Lin Hong a law widely circulated in the computer world - Moore's Law.

Moore's Law was proposed by Gordon Moore, one of the founders of Intel. The content is: When the price remains unchanged, the number of transistors that can be accommodated on the integrated circuit will be doubled every 18 months, and the performance will also be doubled. In other words, the performance of the computer that can be bought per dollar will more than double every 18 months.

Computers have been following this law until now. Although it is not very accurate, on the whole, this law is still very accurate.

"I still have too little knowledge." Lin Hong sighed. It's not the first time he has thought so. Compared with Arthur and others, he knows too little. This is mainly because he has almost no previous channels to obtain the latest scientific and technological knowledge. The content seen in the library is basically decades ago.

Then, Arthur started the computer, and after a while, a very beautiful operating system was displayed in front of Lin Hong.

It looks much better than the operating system of the computer in his room, and the graphical interface is directly in.

"This is the latest operating system released by Apple last year, called Mac_System_Software_6 series..."

Arthur took the initiative to introduce to Lin Hong.

"This is the most popular graphics operating system so far. Microsoft's Windows has referenced his design in many aspects, but it is not as exquisite as this system at all. Microsoft's interface is too rough. Oh, my God, it took me several years to replace it!" Arthur seems to be recalling a nightmare.

He looked back at Lin Hong and said, "I moved that computer to your room. Although it is a little outdated now, it can still be used normally. Moreover, its configuration is a little better than that of the computer in our school computer room. If you like it, you can use it as you like.

Lin Hong nodded: "I like that machine very much, thank you!"

Arthur then showed Lin Hong how to send and receive emails on the computer.

To start the first email, you must first use the modem to dial up the Internet, and then use the mail processor Pine to write and send emails.

Arthur filled in the other party's email address and his own address, then wrote a little casually and sent an email to Matthew.

In less than a minute, the system prompted that a new email had been received. After opening it, I saw Matthew's reply. He also sent a picture in the email.

Is it that simple?

After reading it, Lin Hong felt that the sending and receiving of this email was too simple, but then again, if he hadn't seen it with his own eyes, he couldn't imagine what was going on. Only when you have seen it with your own eyes can you have a more intuitive understanding.

In fact, the key is to dial-up Internet access. According to Arthur, this is charged, which is the same as the phone charge for making a phone call.
