What are the electronic components of the first computer in the world?

What are the electronic components of the first computer in the world? Answer: the electronic components of the world's first computer are vacuum tubes. That is to say, the main internal components of the first computer in the world are vacuum tubes, not later transistors.

Interpretation:

The invention origin of electronic tube:

The invention of the electronic tube was much earlier than that of the transistor. As early as 1883, Edison, the king of invention, placed a small section of copper wire near the carbon wire of the vacuum bulb. Edison was puzzled that although the copper wire did not contact the carbon wire, there was a weak current in the circuit connecting the copper wire. In fact, this is the reason why the heated carbon wire radiates electrons around. Because Edison didn't pay attention to this discovery, he just named it the Edison effect.

In 1904, the first electronic tube in the world was really invented by the British physicist Fleming, and the patent right of the electronic tube was the British physicist Fleming.

Principle of electronic tube:

It can be seen from the invention process of the electron tube that the working principle of the electron tube is to emit electrons by the cathode, then receive them at the anode, and then according to the control of the intensity of the electrons emitted by the cathode, you can get different intensities of current, so as to achieve the signal amplification effect, which is the working principle of the electron tube.

Advantages and disadvantages of electronic tube:

The advantages of electronic tubes are very obvious, that is, strong load capacity and good linear performance. Up to now, electronic tubes are still used as audio power amplification devices in some high fidelity audio equipment. Of course, the disadvantages are also obvious, that is, large volume, power consumption and severe heating.

The first computer came out:

On February 14th, 1946, on Valentine's day, the world's first computer "ENIAC" came out at the University of Pennsylvania in the United States. The main principals: von Neumann, morkley, Eckert, Goldstein and Chinese American Zhu Chuanyu. The main internal device of the first computer is the electronic tube, which covers an area of about 170 square meters, uses 18000 electronic tubes, weighs 30 tons, and has a power of 150 kW. It can add 5000 times or multiply 400 times per second.

Transistors came out only in 1947.
