When did the first computer come out? Beginners must read: When did the world's first computer appear?

php editor Apple takes you to explore the birth process of the world's first computer. The development of electronic computers can be traced back to the 1940s. The world's first electronic digital computer, ENIAC, was born in 1946 and is regarded as the prototype of modern computers. The birth of ENIAC marked the beginning of computer science and opened a new era of computer technology. A thorough understanding of the birth of the first computer is crucial to understanding the development and future trends of computer science.

The world’s first computer, that is, the first general-purpose computer, was produced in 1946. It was developed by two scientists from the United States, Mowgli and Eckert, and was jointly launched by the University of Pennsylvania. , was finally born. After the birth of the first computer, the U.S. Department of Defense attached great importance to it and tried to use this machine to complete ballistic calculation experiments. The world's first computer was very large, with nearly 20,000 photoelectron tubes, covering an area of ​​170 square meters.

1. Huge size

The first computer in the world was huge, not what people use now With an extremely light body in the hand, the weight of the computer at that time was 30 tons. At the same time, the power consumption to support its operation was extremely large, with a power of about 150kw. This computer performs operations more frequently and can support more than 5,000 operations per second. Although it cannot be compared with modern advanced computer technology, it is undoubtedly an existence that transcends centuries and has extremely high reference significance in the past.

Because there were a large number of electron tubes inside the machine, this first computer was also called an electron tube computer, and it was the first computer of all computers. The primitive existence among them. The distribution of a large number of electron tubes makes this computer very large in appearance. At the same time, due to its high power, it is likely to generate heat, so it cannot be run for too long at a time. People usually refer to the world's first computer as the first computer. The reason why electronic computers can be equated with computers is because computers were developed to help people process some information and calculations, and they have the same functions as early computers.

2. Computers have become an important tool

Electronic computers replace people’s brains for automatic calculations and efficient processing Some information is actually a tool to help people's brains improve their processing capabilities. Therefore, a computer is the same as an electronic computer, and an electronic computer is also a computer. As time goes by, human science and technology level has improved significantly, and the application range of electronic computers has become more and more extensive.

In addition to being able to process information efficiently and complete a number of scientific operations, today’s computers have expanded their application scope and It has spread to all aspects of human life. Modern humans cannot do without computers. Whether it is high-level scientific research or dealing with small things in daily life, computers can be completed very well and have become the most important tool for humans. The inventor of the computer has undoubtedly benefited all mankind.

The most hostile desert in the world is the Atacama Desert. For nearly a century, there has been no rain in the Atacama Desert, which has caused great suffering to the residents living nearby. The Atacama Desert is very vast, not only spanning many countries, but also covering a total area of ​​200,000 square kilometers. The Atacama Desert has been considered the driest region in the world in recent years. However, in There are more than one million residents living there.

1. Use dense fog to get water

If residents living in the Atacama Desert want to obtain water, they have to climb up the mountain to obtain water in the thick fog on the top of the mountain. . The locals made a very special tool called a mesh screen. They used these mesh screens to cover as much dense fog as possible inside, and then converted it into moisture through a special refining method. According to statistics, local residents can obtain more than 1,000 kilograms of water every day through this method.

After obtaining water, residents use the water to grow crops or grow pasture to develop animal husbandry and make the area a certain development and can solve the problem of food and clothing. In this regard, the wisdom of the local people is endless. Even though the environment of the Atacama Desert is very harsh, there are many unique natural landscapes there. There are large areas of salt-alkali land and very rare snow volcanoes in the Atcatama Desert. Due to its special geological structure and the extremely arid desert surface, it has even formed many protrusions and depressions, like lunar rings. From a distance, it looks like the lunar surface, which is very special.

2. Biological survivability is strong

Before 2015, the Atacama Desert had nearly 100 It hasn't rained in years. In 2015, the Atcatamar Desert finally received its first rainfall. This heavy rain awakened many plants in the desert and finally emerged from the salt-alkali land. In the sandy soil full of gravel, many grasses and flowers bloom everywhere, ushering in their spring and summer. Although this group of plants may not live for too long due to drought, they have a strong ability to survive. With their roots here, they will start to grow again whenever they encounter a little moisture.
