If 1 thousand modern people go back to 1.5 million years ago, how long will it take to build a computer?

If 1, modern people go back to 1.5 million years ago, how long will it take to make computers?

Now, when we assemble a computer, you will find it very simple. Just buy CPU, hard disk, graphics card, motherboard, power supply, chassis, memory and other materials to assemble it. These individual materials are produced by their own manufacturers. We don't need to know how these materials are produced, just how to assemble them into computers.

CPU:

It is the central processing unit of the computer, the control and operation core of the whole computer, and it is the most difficult to manufacture. Recently, netizens have discussed that mask aligner, which is relatively hot, is an indispensable and important component for manufacturing it, and there are also processes carried out by etching machines, polishing machines, ion implantation and other equipment.

We often hear that this chip uses a process of several nanometers. What does this process of several nanometers mean? Why is the smaller the better?

the meaning of nanometer process: the so-called nanometer process refers to the line width of the gate in the transistor, or the distance between the source and the drain in the transistor. When the transistor works, the current flows from the source to the drain. If the distance between them can be shortened, it means that the overall size will become smaller, and more circuits can be integrated in the same size area, and the performance will be higher. This is what we often hear about the process of several nanometers. The smaller it is, the more advanced the process will be.

storage device:

a storage device is a part of a computer that stores data. Without it, the computer will lose its memory and will not work. There is a memory that uses electric energy to store information and a hard disk that uses magnetic energy to store information, both of which are indispensable parts of a computer.

motherboards, graphics cards and other components are not much to talk about. Regardless of the manufacturing process, they are made of various materials, such as silicon, lead, copper, gold, tin, aluminum, arsenic, mercury, cadmium and so on. Basically, most elements in the periodic table are involved, and there are various additives.

The operation and calculation of computer also need computer language, which includes various disciplines. How does the computer realize the task with "" and "1"? How to relate their meanings to electrical signals? For example, people can specify that stands for low voltage and 1 stands for high voltage, so that electrical signals are related to computer language. Simply put, as long as the information can be converted into digital signals, it can be processed by computers.

computer computer is a master of modern human science and technology, representing the current level of human science and technology. It is a knowledge-and technology-intensive industry, and it is a synthetic product of metallurgy, chemical industry, precision instrument manufacturing, semiconductor industry and so on, without a link.

If 5, of these 1, modern people are computer engineers and senior technicians, and 5, are senior technicians, and the division of labor is clear, some are responsible for exploration and mining, some are responsible for metallurgy, manufacturing, design and programming, and so on, I think it will take less than 2 or 3 years for them to manufacture computers 1.5 million years ago. Of course, this kind of computer is the same as the first one.

ENIAC is the first human computer. It covers an area of 17 square meters and weighs 3 tons. It uses 18, tubes as a whole and can only perform 5, operations per second.

If 1, modern people are ordinary people, then there is no time limit for this. Even if their highest goal is to make computers, they must follow the law of development of things. The knowledge level of 1, ordinary people is equivalent to the highest wisdom in Galileo's era, but it is not as good as that in Newton's era. After all, few ordinary people know calculus, and Newton has made great achievements in mechanics, mathematics, astronomy and heat.

I think 1, ordinary people should first consider how to survive, and then multiply to make more people, so that the probability of genius appearing in future generations will be higher. Judging from the historical experience, it is only a few geniuses who push science forward in great strides. Of course, it can't be so absolute. After all, Newton made great achievements by standing on the shoulders of his predecessors.

Back to the topic, if it is 1, modern ordinary people, it will take 4 years at the earliest to create "ENIAC".
