What John von Neumann invented

Got it, Little Science Episode 248 John von Neumann.

Feng. Neumann's three principles are:

1. The computer is composed of five parts: controller, combinator, memory, input device and output device.

2. Programs and data are stored in the memory indiscriminately in the form of binary **, and the storage location is determined by the address.

3. The controller works according to the instruction sequence (program) stored in the memory, and is controlled by a program counter to execute the instruction. The controller has the ability to judge and select different workflows based on the calculation results.

The basic idea of the von Neumann principle is mainly threefold:

1. The computer hardware should be composed of five parts: controller, combinator, memory, input and output;

2. Store the program, let the program command the computer to complete various tasks automatically;

3. The basis of computer computing is binary; Stuffy code shooting.

The American-Hungarian scientist von Neumann was the first to put forward the idea of program storage, and successfully applied it to the design of computers, and the computer built according to this principle is called the von Neumann structural computer, because of his outstanding contribution to modern computer technology, so von Neumann is also known as the "father of computers".

At the heart of von Neumann's principle is "stored program control".

1) Representation of data and instructions in binary form.

2) The program (data and instruction sequence) is stored in the main memory in advance, so that the computer can automatically take out the instructions from the memory at high speed and execute them when working.

3) A computer system consists of five basic components: combinator, memory, controller, input device, and output device, and stipulates the basic functions of these five components. Von Neumann's thought is actually the basic idea of electronic computer design, which laid the basic structure of modern electronic computers.

The von Neumann structure, also known as the Princeton structure, is a memory structure that combines program instruction memory and data memory.

Feng. Neumann Structure Processor Features:

1.There must be a memory;

2.There must be a controller;

3.There must be a combinator for both arithmetic and logical operations;

4.There must be input and output devices for human-machine communication. In addition, programs and data are stored uniformly and work automatically under program control.

Key points of von Neumann's theory:

1. The computer hardware equipment is composed of five parts: memory, combinator, controller, input device and output device.

2. The idea of storing a program - the calculation process is described as a program composed of many commands in a certain order, and then the program and data are input into the computer together, and the computer processes the stored programs and data to output the results.

John von Neumann (December 28, 1903 - February 8, 1957), an American-Hungarian mathematician, computer scientist and physicist, graduated from ETH Zurich, an important founder of modern electronic computers and game theory, and is known as the father of modern computers and game theory. He has made significant contributions to many mathematical fields such as functional analysis, ergodic theory, and geometry, as well as to computer science, quantum mechanics, and economics.

His name is often seen in the field of computers and mathematics, and von Neumann, one of the world's greatest scientists, was a Jew and even more so a Hungarian-American. Von Neumann was a genius scientist with an IQ beyond the average and a memorable memory. Von Neumann's achievements in many fields such as modern computers, game theory, nuclear and biochemistry can be called fruitful.

Then there is von Neumann's achievements in game theory. Von Neumann is called the "father of game theory" by later generations, this is von Neumann's contribution to social science, it was von Neumann who founded the discipline of game theory, von Neumann and Morgenster's "Game Theory and Economic Behavior" is a foundational work in this regard, this theory is widely used in the field of economics, and now, this theory is more widely used.
