What was the name of the first electronic computer in the world? 1003 untitled.

The first electronic computer in the world was called ENIAC.

The first computer in the world is the electronic numerical integration computer, abbreviated as ENIAC, which was born in the University of Pennsylvania in 1946. The first computer in the world, the first general-purpose computer, was produced in 1946. It was developed by two American scientists, Moakley and eckert, and jointly launched by the University of Pennsylvania, and was finally born.

After the birth of the first computer, the U.S. Department of Defense tried to complete the experiment of ballistic calculation with this machine. The first computer in the world was huge, not a notebook computer that people now hold in their hands, but compared with a heavier desktop computer, it was just a drop in the ocean.

At that time, the light weight of the computer was 30 tons, and the power consumption to support its operation was huge, and the power was about 150kw. This computer has a high operation frequency and can support more than 5000 operations in one second. Although it can't be compared with modern developed supercomputers, it is undoubtedly a cross-century existence and has great reference significance in the past.

Development of computer

According to the different physical devices used in the computer, it can be divided into four stages. The first generation of electron tube computers, which started in 1946, was CPU-centric in structure, used machine language, was slow and had small memory, and was mainly used for numerical calculation.

The second generation transistor computer, which started in 1958, is memory-centric in structure, and uses high-level language to extend its application to data processing and industrial control.

The third generation of small and medium-sized integrated circuit computers began in 1964. The structure is still centered on memory, and various external devices are added. The software has been developed to a certain extent, and the computer's function of processing images, characters and data has been strengthened. The fourth generation is large-scale and very large-scale integrated circuit computers, which started at 197 1. With the appearance of microcomputers, they are more widely used.
