Honghuang, I am engaged in science and technology in the Wuzu

The Ice Banshee was shocked, at first she came here just with a playful attitude, and then came into contact with this kind of thing and found it useful for her cultivation, but now she knew that there was a person here trying to copy the Heavenly Dao, it was too crazy.

In the Flood Barren Continent, cultivation was full of difficulties.

Although it is not difficult to cultivate to the realm of heavenly immortals, as long as there is talent, the flood desolate creatures are almost perfect, but the cultivation of the golden immortal level requires a long accumulation, and the talent is better requires millions of years, almost tens of millions of years.

It is even more difficult to cultivate to the Taiyi Golden Immortal, and without special opportunities, it is impossible without hundreds of millions of years.

As for the Da Luo Golden Immortal, ordinary Taiyi Golden Immortals need tens of billions of years, even if it is the innate three races during the Longhan Tribulation period, it will take billions of years to have the supreme creation of the heavens.

Today’s Daluo Golden Immortals are basically creatures left over from the Longhan Tribulation, or innate spirit fetuses that have been brewing for tens of billions of years.

Cultivation needs to rely on the strength of a person, it needs to go through a lot of calamities, she has seen too many amazing cultivation geniuses in the more than 100 million years of her existence, but they all bloom like fireworks, and finally dissipate in the endless heaven and earth calamities, and there are very few gods like her who can be lucky enough to survive.

Above Da Luo is the quasi-saint, and those who can reach the quasi-saint are all masters of one side, a generation of grandmasters, which shows how rare it is.

As for the saints, they have never seen a single one who has become holy by their own strength, and not everyone can complete the immeasurable robbery of mana alone.

How long is the immeasurable robbery? The answer is 30 billion billion years, which is really old.

However, science can rely on the power of many people and use the wisdom of all living beings to simulate the entire world, without worrying about various disasters like cultivators.

The computer uses countless switches to calculate, and there are also many calculations to be carried out in practice, and you can only rely on yourself, which is very exhausting, but the computer does not need mental power at all.

Even if the scientific and technological preaching is unsuccessful, the computer is also a magic weapon that makes practitioners crazy because of the huge computing power.

“Two switches can calculate four bits of data, three switches can calculate eight bits of data, four switches can calculate 16 bits of data, and so on, 16-bit data can calculate 2^16 data, that is, one megameter, if it is 32-bit data, then 1G can be calculated, if it is 40-bit data, then 1t of data can be calculated, and so on, the entire universe can be calculated using less than a hundred bits of data.”

“The oscillator design is successful, the next idea is to use the oscillator to control the tube, if the design is successful, then use the oscillator to control two tubes, design a two-digit decoder, use two data to control four numbers, and add this technology to our telegraph to make sending and receiving telegrams easier.” Fang Hao looked at the contemplative Ice Banshee and said, and began to point her research ideas.

“So will you gradually design three-, four-, five-digit, or even hundred-digit computers?” The Ice Banshee asked.

“Naturally, if this kind of control is achieved, we can study how to make this control simulate everything, such as these 10,000 small light bulbs, we can use the computer’s control ability to make the light bulb dynamically display text or images, instead of now only displaying static images, if you want to display another image, you have to manually switch and dial the code.” Fang Hao said, pointing to a few words displayed by the 10,000 light bulbs in front of him.

In fact, these bulbs are used to study how to draw text display lights, and many IO tables for displaying related text have been developed to lay a good foundation for future text display technology.

If you want to display a text, then you have to refer to the IO table for dialing, control 10,000 bulbs each time need to control 10,000 switches, summarize some of the rules inside can reduce the number of dials, such as controlling several switches at the same time, this research is the lowest level of computer research, is the cornerstone of modern society computer software.

For the next stage of research, Fang Hao mobilized the backbone of the entire information department, and more than thirty people began to use clock signals to control the research of electronic tubes.

Tubes can be divided into vacuum diodes and vacuum transistors, which are the basic components for establishing logic gates and are manufactured according to the logic gate principle.

Vacuum diode is a component that can control the signal on-off, composed of cathode and screen level, two electrodes are packed inside the glass bottle, the inside of the glass bottle is pumped into a vacuum, in order to facilitate the flow of free electrons, but also can effectively reduce the oxidation loss of the filament.

The cathode is where the flow of electrons is released, consisting of a filament and a metal plate, from which electrons are dispersed in small vacuum glass bottles when the filament heats the metal plate.

The screen is a metal plate at the other end of the tube, and the screen is connected to a positive voltage, which is responsible for attracting electrons emitted from the cathode as the end point of the electron’s free travel.

The vacuum transistor is a component that amplifies the signal, which has an additional gate between the cathode and the screen than the vacuum diode.

The gate is a circle of thin coils, like a fence, fixed between the cathode and the screen, the flow of electrons must pass through the gate to the screen, and the voltage between the gates can control the electric field to affect the flow of electrons, and its role is like a faucet, with the function of circulation and blocking.

The vacuum transistor can control the gate voltage and control the current through the vacuum transistor cathode to the screen.

Why do tubes remove the air from the glass tube? Because the electron will collide with the constituent molecules in the air during its emission process, the electrons ejected by the cathode will hit the air in the tube, causing the atoms of the air to be excited to an excited state, thereby producing blue light and losing energy.

Filament, cathode, gate, screen, etc. are packaged in a glass tube, and the inside becomes a vacuum state, in order to achieve the highest efficiency of the electron radiation action, and this glass tube is the so-called vacuum tube, if the vacuum degree is insufficient, it will seriously affect the working performance of the vacuum tube.

Vacuum transistor is the basis of the amplifier, the computer is indispensable to its figure, the triode has voltage amplification tube and power amplifier tube two, voltage amplification tube internal composite two identical transistors, power amplifier tube energy consumption, large size, mainly used for the final power output.

In addition to vacuum diodes and vacuum triodes, there is also a component called quadrode, which is a low-frequency power amplifier tube, and the beam screen connected to the cathode can make the anode current larger, suitable for doing high-power amplification circuit naturally, which is only a supplement to the tube, in fact, the transistor and diode can constitute a powerful computer.

If you want to use the clock signal to control the tube, you must first make a trigger, and to make a trigger, you must first make a basic logic gate circuit, and the logic gate circuit needs to be made using diodes and transistors.

Therefore, the research content at this stage is to use diodes and transistors to make logic gate circuits, there are mainly three kinds of logic gates, and gates, or gates, and non-gate circuits.

Just saying it is so long, it is enough to see the complexity of semiconductor technology, and there is no possibility of short-term overtaking.

Just make it with a functional logic gate or not, but also need to consider energy loss and electrical performance, because the tube is a high-power component, the loss of energy is very serious, will produce a lot of heat, how to reduce the loss of energy is a huge issue.

The logic gate circuit of the tube is the same as the circuit of the transistor and MOS tube, except that the tube controls the signal through the gate voltage, while the transistor controls the signal through the PN junction, and the MOS tube controls the signal through the conductive channel.

………………

Through a large number of mathematical calculations, hundreds of logic gate circuits were formed, and in order to select the logic gate circuits that were actually available, a large number of boundary test experiments were carried out, so that they could be used in a large number of computers.

Although the logic gate circuit is simple, the electrical characteristics of the tube can be understood more deeply during the experiment, so Fang Hao did not directly take out the mature experimental results of modern society, but led everyone to study little by little, and used the elimination method to select the optimal logic gate circuit.

The third scientific and technological revolution in the 20th century is the era of electron tubes, and later triodes and MOS tubes were produced, and these basic research carried out by Fang Hao now is very important, but the original motherland has missed the golden age of the development of the third scientific and technological revolution, and it has to sigh.

Regarding the detailed parameter analysis of various logic gates, in various countries are top-secret information, which is also the reason why the chip modern social industry is weak, because the Celestial Empire does not have enough accumulation of technical data in this regard, which is also the reason why the domestic chip industry can not copy, the same design, the product is worse than imported chips.

To complete the accumulation of these basic data, it is not only possible to complete in a short time, not only requires a huge investment, but also because the technology is outdated and does not generate benefits, seriously discourages investment enthusiasm.
