Who invented the first electronic computer?

The first electronic computer.

In World War II, the United States participated in the war as an Allied Nation. The U.S. Army asked the Department of Electrical Engineering at the University of Pennsylvania's Moore College and the Aberdeen Ballistics Research Laboratory to work together to provide six fire meters per day. Hundreds of ballistics had to be counted on each table, and the task was both onerous and urgent.

It takes 20 hours to calculate a trajectory with a 60-second flight time with a desktop calculator, or 15 minutes with a large calculus analyzer. The Aberdeen Laboratory employed more than 200 computing experts at the time, and even then, a firepower meter often took two or three months, which was simply not enough to meet the operational requirements.

In order to get out of this passive situation, it is imperative to quickly develop a method and tool that can improve computing power and speed. The chief engineer who led the development of this work at that time was the 23-year-old Eckert, who cooperated with a number of scientists, and after more than two years of hard work, finally succeeded in building the world's first electronic computer, named "Electronic Digital Integration Computer", or ENIAC for short, at the end of 1945.

This amazing electronic computer is like a behemoth, containing 18,000 tubes, covering an area of 170 square metres and weighing 30 tons. With 5,000 additions or 400 multiplications per second, it is more than 2,000 times faster than the previous desktop calculators used to calculate ballistics. Since then, mankind has entered a completely new era in the field of computing.

The first electronic computer was invented by Mauchley.

In 1946, the world's first electronic computer "ENIAC" was born at the University of Pennsylvania in the United States, causing a great sensation in the world. Its inventor, Mauchly John William, became famous for this and is known as the "father of the computer".

The U.S. Department of Defense used it for ballistic calculations, it was a behemoth, using 18,000 tubes, covering an area of 170 square meters, weighing 30 tons, consuming about 150 kilowatts of electricity, and performing 5,000 calculations per second, which seems insignificant now, but was unprecedented at the time. ENIAC uses electron tubes as components, so it is also known as tube computers, which is the first generation of computers. Tube computers cannot work for too long because of the large volume of the tubes used, the power consumption is large, and they are easy to generate heat.

The first computer was invented by von Neumann. Computer, commonly known as computer, is a modern electronic computer used for high-speed calculation, which can perform numerical calculations, logical calculations, 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.

First computer:

A computer that is composed of a hardware system and a software system and does not have any software installed is called bare metal. It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photon computer trainers, quantum computers, etc.

The application of computers is becoming more and more common in China, after the reform and opening up, the number of computer users in China has been rising, and the level of application has been continuously improved, especially in the fields of the Internet, communications, and many other fields. From 1996 to 2009, the number of computer users increased from 6.3 million to 67.1 million, and the number of networked computers increased from 10,000 to 59.4 million. Internet users have reached 100 million, and there are 100 million mobile Internet users on the wireless Internet, of which 100 million mobile Internet users have access to the Internet, ranking first in the world.

The first electronic computer was invented in 1946, and the bulky and expensive computer was mainly used to perform scientific calculations, especially military subjects.

For example, ENIAC was first used to calculate the trajectory of artillery and to calculate the neutron density of cross-sections when designing hydrogen bombs (many supercomputers still play a huge role in simulating the late closure of nuclear tests).

The CSIR MK I, the first storage program computer designed in Australia, was designed to assess the falling code cracking rain in the catchment area of a hydropower project.

Others were used for decryption, such as the British Colossus programmable computer. In addition to these early scientific or military applications, the spread of computers in other fields is also very rapid.

From the very beginning, stored program computers have been associated with solving business problems. Long before the birth of IBM's first commercial computer, the British JLeons et al. have designed and manufactured LEOs for asset management or other commercial purposes.

Rather than continuing to control size and cost, computers began to spread to smaller organizations. Coupled with the invention of the microprocessor in the 70s of the 20th century, cheap computers became a reality.

The first electronic computer was invented in 1946, and the computer is a small, lightweight, easy-to-carry, practical and inexpensive handheld computing device that runs on an embedded operating system and embedded application software. It's simpler and lighter than a laptop in terms of size, features, and hardware.

In addition to managing personal information (such as contacts, plans, etc.), the handheld computer can also browse pages on the Internet, send and receive emails, and even use mobile phones, but also have: tape recorder function, English-Chinese-English dictionary function, global clock comparison function, reminder function, leisure and entertainment function, fax management function stove line and so on.

The power supply of a handheld computer is usually an ordinary alkaline battery or a rechargeable lithium battery. The core technology of the handheld computer is the embedded operating system, and the competition between various products is also mainly here.

In addition to having all the features of a laptop, it also supports handwriting or voice input, making it more mobile and portable.

The first electronic computer was invented in 1946, and shortly after the invention of the computer, it was discovered that certain tasks had to be performed in many different programs, such as the calculation of certain standard mathematical puzzle functions.

For the sake of efficiency, the standard versions of these programs are collected into a "library" for each program to call. Many tasks often involve dealing with a wide variety of I/O interfaces, and this is where libraries for connectivity come in handy.

In the 60s of the 20th century, with the industrialization of computers, computers were increasingly used to process different jobs within an organization. Soon, special software appeared that could automatically schedule the timing and execution of jobs.

The software that controls both the hardware and the timing of jobs is called an "operating system." An example of an early operating system is IBM's OS 360. In the process of rapid improvement, the operating system has introduced a time-sharing mechanism - concurrency.

The first electronic computer was invented in 1946 and used computers to process, manage, and manipulate various forms of data. Data processing is generally always carried out for some kind of administrative purpose.

For example, the finance department uses computers for bill processing, account processing, and settlement; The personnel department uses the computing surplus to establish and manage personnel files, etc.

Unlike numerical computing, data processing focuses on synthesizing and analyzing large amounts of data. It generally does not involve complex mathematical problems, but requires a large amount of data to be processed and often required to be processed in a short period of time.

In scientific research and engineering design, there are a large number of cumbersome and complex positive numerical calculation problems, and the solution of such problems is often beyond the ability of human resources.

The ability to solve complex mathematical problems with high speed and precision is the specialty of electronic computers. Therefore, numerical computing is still an important field of computer application to this day.
