Hand rubbing nuclear fusion live in the wilderness

Chapter 176 The Level [-] Mission Opens

After carefully comparing the advantages and disadvantages of the first, second, and third generation computers, Han Yuan finally confirmed the goal of his secondary task research and development.

Second-generation computers: "Transistor computers."

The transistor computer was invented and used for less than ten years, and it belongs to the transitional computer in the history of computer development.

But it is undeniable that in the history of computer development, transistor computers occupy a very important position.

Even the third-generation and fourth-generation integrated circuit computers were developed on the second-generation transistor computers.

No matter how integrated, the functions of the various transistor components in the chip in the computer have not changed, but the size of the transistor has been shrinking.

It can be said that without the invention of the transistor, there would be no prosperous network today.

In addition, transistor computers have considerable disadvantages.

Compared with the three generations of integrated circuit computers, transistor computers are still huge.

In addition, a large number of transistors will generate radiation during operation, which will have an impact on the human body's circulatory system, immunity, reproduction and metabolic functions. In severe cases, it will induce cancer and accelerate the proliferation of cancer cells in the human body.

Of course, radiation is not only a shortcoming of transistor computers, but also a shortcoming of all computer products.

Although the transistor computer has various shortcomings, it is still the most suitable for him at present.

It is simple, easy to manufacture, and requires thousands of times fewer transistors than electron tubes.

A tube computer needs at least 500 million tubes to achieve a million calculations per second, but a transistor computer only needs more than 1000 transistors.

Five million to one thousand, five thousand times the difference.

However, this simplicity and ease of manufacture is only relative to the three generations of integrated circuit computers.

A transistor computer, even the simplest kind, cannot do without a large number and variety of transistor semiconductor devices at its core.

As well as supporting core components such as memory, input/output devices, and displays.

And these things need to be slowly produced by Han Yuan alone.

Not to mention anything else, just one transistor is enough to give him a headache.

Be aware that there may be more than one type of transistor element in a crystal computer.

In a broad sense, a transistor is a solid semiconductor device, including diodes, triodes, field effect transistors, thyristors and other devices.

But it is mainly divided into two categories: one is bipolar transistors, and the other is field effect transistors.

These two different types of transistor devices have different functions, some are detection, some are rectification, some are amplifying signals, some are switches, and some are voltage regulators.

And these are the most important components in a transistor calculator.

So how to get the transistor out was the first problem he faced after the start of the second level mission.

The only fortunate thing is that after entering the electrical era in the first four months of the first-level mission, he did not waste the next six months, but worked hard to develop his own technology, researched, developed and manufactured various electrical equipment and various production lines .

Plus rewards for Level [-] quests, industrialization quests, and new material quests.

With these things, he can quickly get out the various materials needed to make transistors, which saves him a lot of time for secondary tasks.

Otherwise, he really wouldn't be able to complete the secondary task.

In two days, Han Yuan went to the Star City Library to read a large amount of information and documents. At this level, there is no more detailed information on the Internet for him to read.

Fortunately, with his current brain, he can quickly understand and memorize while reading.

This kind of ability, which is similar to the memory of the protagonist in the novel, should have been brought about by the previous genetic medicine.

Even after a whole year has passed, the ability of genetic medicine seems to be still being developed.

So far, Han Yuan has discovered several incredible skills from himself.

For example, the instinct to start a fire when the genetic potion ability was discovered for the first time, the enhanced manufacturing when it was discovered for the second time, and the learning ability later.

The genetic medicine provided by the system is like a taboo-like power, and like a god, it is constantly opening the windows of his body.

Han Yuan thought about where this kind of thing came from more than once, who made the system, and what purpose it had, but in the end there was no result.

It's like he is shrunk above Wuchang's head like a dark cloud now, no matter how Wuchang searches and guesses, he can't find him or determine his source and purpose.

The system is also a knot in his heart, a cloud.

The beating countdown on the virtual screen was only ten minutes away. Taking advantage of the last bit of time left, Han Yuan called his parents and said that he would go out to play again next time.

The number jumped bit by bit until it returned to zero, and the sound of the system's improvement sounded in my mind at the same time.

"Ding, the second level mission is on!"

"Level 360 task requirements: successfully develop an electronic computer that can be used for high-speed calculations within [-] five days and record relevant data (the calculation speed is not less than one million times per second), and the live broadcast time is not less than eight hours a day."

"Second task reward: carbon-based integrated circuit board preparation information."

"Instructions for the secondary task information: The secondary task can be completed ahead of schedule, and there will be additional rewards for early completion. The additional rewards will depend on the amount of time left for the host to complete ahead of schedule."

"Please host to go to the different space to complete the task as soon as possible."

Hearing the voice, Han Yuan didn't delay, and said casually: "System, enter the simulation space!"

As soon as the words fell, he appeared in the simulation space again.

"Wow woo woo."

Before he could fully see the scene in front of him, he heard the howling sound of a ferocious beast.

With Won's current judgment and reaction, he knew what was going on in an instant.

Looking back, as expected, he is now in the studio next to the wooden house.

The most amazing thing is that after he appeared, his right foot just stepped on the small paw stretched out by the sleeping leopard.

Being stepped on by him, it may be hurt by the step, or it may be frightened by his sudden appearance. Leopard woke up with a start, screamed in horror, and took off directly on the spot, jumping two meters high.

And Leopard [-] who was sleeping on the side was also taken aback by his brother's behavior, staring blankly at Leopard [-] who hadn't landed yet.

"Tsk tsk, felines are good at jumping."

Seeing the leopards jump more than two meters high one by one, almost jumping to the roof, Han Yuan sighed.

This kick wasn't very heavy, and it didn't hurt Leopard Yi, it just means that the mental fright might be more serious.

After all, if a person suddenly appeared like a ghost and stepped on your foot, it is not bad for Leopard to bite directly without being frightened.
