In the same year, Walter Aiken of the United States built the first new type of computer, named "Mark 1". The computer was huge, made loud noises when operated, and could only handle two additional problems per second, but it was the first computer after all.
2.Generally speaking, the world's first computer was designed and developed in 1945 by two professors at the University of Pennsylvania - Mochley and Eckert. However, before that, people had been working on computers for a long time.

1946 year.
The evolution of computing tools has gone through different stages from simple to complex, from low-level to high-level, such as from knotted knots in knotted records to abacus, abacus slide rule, mechanical computer, etc. They have played their respective historical roles in different historical periods, and at the same time, they have also inspired the development of modern electronic computers.
Computer (computer), commonly known as computer, is a modern electronic computer used for high-speed calculation, which can carry out numerical calculation, logical calculation, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed.
In prehistoric times, the German scientist Chickkad (built the first mechanical computer ever built by mankind, which was capable of addition, subtraction, multiplication and division of six digits. This epoch-making invention laid the foundation for the development of human computers. Perforated paper tape, binary, Boolean algebra, hand-cranked computers, and push-button computers began to appear, laying the methodological and theoretical foundation for the emergence of digital computers a hundred years later.
In the era of the tube, ENIAC was unveiled in Philadelphia in 1946, and it was programmed by rewiring between different parts and had parallel computing power, but it was limited in functionality and slow. The advent of ENIAC marked the birth of the modern computer and was a milestone in the history of computer development.
Later, the invention of the transistor greatly contributed to the development of computers, with transistors replacing electron tubes and electronic devices reducing in size.
In 1956, transistors were used in computers, and transistors and core memory led to the creation of the second generation of computers. Second-generation computers are smaller, faster, less power-consuming, and more stable in performance. The first to use transistor technology were early supercomputers, which were mainly used for the processing of large amounts of data in atomic science, which were expensive and produced in very small quantities.
Benefits of Computers:
Search for informational materials. A computer connected to the Internet can use a search engine to find the information and materials you need. It is currently the most widely used search engine, fill in the input box with the keywords you want to find the information, and then press enter, and the lead key computer will immediately present all the relevant information in front of you.
Documentation. Using the commonly used office software on the computer, you can use a variety of documents on the computer, such as the most commonly used word, side excitation excel and ppt documents. The image below shows the page of OfficeWord. <>

In World War II, both sides used aircraft and artillery to bombard each other's military targets. To be accurate, it must be accurately calculated and plotted"Shooting charts"。Only by checking the table can the angle of the muzzle be determined so that the shell fired can hit the flying target.
However, each number has to be calculated by doing four operations thousands of times, and a dozen people use a hand-cranked mechanical computer to calculate for several months to complete a number"Charts"。In response to this situation, people began to study the use of electron tubes as a"Electronic switches"to improve the computing speed of the computer. Many scientists took part in experiments and research, and finally made the world's first electronic computer, which was named"Eniake"。
Extended Materials. Functions: 1. Documentation. Windows 10's built-in Notepad and WordPad applications are easy document processing software.
In addition, users can also install powerful word processing software like word in the system, and use these software to perform documents and text layout, insertion and other operations.
2. Data management. Computers were originally used to analyze and process data, so data management is one of the main functions of computers. In many enterprises, most of the computers are installed with the best processing software - Excel.
The software can not only make the hashed data into **, but also arrange and filter the ** data.
3. Browse and process. Users can browse and work on their computers**. There are many software to browse**, you can use the **Metro application and Windows** viewer that comes with the Windows 10 system, you can also install ACDSEE software and use the software to browse**.
If it's useful, don't forget to adopt it!

In September 1956, China sent a delegation to the Soviet Union to investigate computing technology. The head of the regiment is Min Naida, the deputy head is Wang Zheng, and the members of the regiment are Wu Jikang and Fan.
Xin Bi, Xia Peisu, Zhou Shouxian, Sun Su, Mo Gensheng, Xu Xianyu, Yan Youguang, translators Zhang Wei, Mu Lili, Li Xiangsheng and other 15 people. The host unit of the former Soviet side was the Institute of Fine Mechanics and Computing Technology of the USSR Academy of Sciences. For more than two months, the delegation inspected the scientific research, production, and education of computing technology in Moscow and Leningrad, and focused on the study of the M-20 computer.
In April 1957, China ordered the M-3 computer and computer drawings through the first channel. On the basis of the investigation and the acquisition of drawings, the development work began. Headed by Zhang Zichang and Mo Gensheng, the M-3 (code 103) computer engineering group was organized.
Through the efforts of all the research and development personnel and the close cooperation of the Beijing Cable Power Plant, China's first digital electronic computer was successfully developed on August 1, 1958. This tube computer, with an operation speed of 30 times per second, fills the gap of modern electronic computers in China.

The formation of planets can be roughly divided into two situations from a formal point of view, the first is that the substances that form celestial bodies gather together and constantly collide and rub against each other, and eventually form planets. >>>More
I bought a Founder computer 10 years ago with only 16MB of memory and hard drive, the original brand, more than 12,000 yuan, and now?!
The gemstone that represents each month is called the "birthstone" or "birthstone", and it was widely believed that the birthstone has the magic power to ward off evil and protect the body, and can bring good luck to people.

After reading this article "The Birth of a Champion Mother", I was deeply moved and inspired. The story mainly tells the story of a mother who got up before dawn to cook for her son, and then walked 30 miles to school as fast as possible to deliver food to her son, and this is the case every day. From the beginning, she was worried about her son's tuition fees, and every day after delivering meals to her son, she picked up vegetables to sell at the market. >>>More
