Since when did you get a computer?

It was in 1846, when the first computer was the size of a school.

The history of computers can be traced back to the late 19th century, when scientists invented some early computer devices, such as differential and analytical machines. However, the first electronic digital computer was designed and built in 1941 by Professor John Van Neumann of Cornell University, which is considered the beginning of the modern computer. Since then, the development of computers has accelerated, such as ENIAC (1946), EDVAC (1951) and UNIVAC I (1951).

The first personal computer was the Altair 8800, which was introduced in 1975.

The first computer was the ENIAC general-purpose electronic computer born at the University of Pennsylvania in the United States on February 15, 1946.

A computer is a machine that uses electronic principles to process data based on a series of instructions. A computer can be divided into two parts: a software system and a hardware system.

People refer to computers with no silver traces and any software installed on them as bare metal. With the development of science and technology, there are now new states selling some new computers: biological computers, photonic computers, quantum computers, etc.

With the increasing popularity of computers, computers have entered almost all industries and played a pivotal role. It has become an indispensable tool for the normal operation of today's society, and computers occupy such an important position in modern people's lives.

In the 40s of the last century, there was a prototype of a computer.

A computer is a machine that uses electronic principles to process data based on a series of instructions. The socks computer can be divided into two parts: the software system and the hardware system.

The first computer was at the University of Pennsylvania in the United States on February 15, 1946.

Birth of the ENIAC general-purpose electronic computer.

In 1936, the British mathematician Turing first proposed a kind of computing mechanism that uses the interaction between the program and the input data to produce the output. In 1938, the first computer "Z-1" to use relays for work appeared, but relays had a mechanical structure and were not entirely electronic devices. In 1942, Atanasov and Bailey invented the first computational pruning machine using a vacuum tube, which was named ABC after the initials of their names.

However, ABC can only solve systems of linear equations and cannot do any other work. Under Turing's guidance, Colossus, the first computer that could write programs to perform different tasks, was not created in England until 1943 for code-breaking. The first modern electronic computer in the history of mankind is recognized as ENIAC in 1946 at the University of Pennsylvania in the United States.

Elementary 4 mathematics began to use calculatorsThe calculator is generally composed of combinators, controllers, memory, keyboards, displays, power supplies and some optional peripherals and electronic accessories, which are composed of manual or mechanical equipment. The combinator and controller of the low-grade calculator are simple serial operations by digital logic circuits, and their random access memory is only.

One or two units for cumulative storage.

Modern Development:Early calculators were purely manual, such as abacus, abacus, etc. The abacus is usually made of sliding beads.

In the West, the abacus was used for centuries before Arabic numerals became popular in India, and is still widely used in bookkeeping and commerce in modern China. Later came the mechanical calculator.

At the beginning of the 17th century, there was a great development of the rapid dismantling calculation tools in Western countries, and the English mathematician Napier invented it"Napier counts"The English priest Ochhard invented the cylindrical logarithmic slide rule, which can not only do addition, subtraction, multiplication and division, multiplication, and square operations.

Roughly since 1994 (when Windows 95 was released), it has been attacked as a must-have household appliance for some high-income families

The brain configuration is relatively very backward.

The time of complete crazy popularization was after 2002, that is, at the same time that Windows XP began to be popularized, computers entered the family, and some developed countries almost reached the level of "one machine per person".

The original meaning of computer was "calculator", that is, humans invented computers to help with complex number crunching. The concept of this artificial calculator can be traced back to the great French thinker Pascal in the seventeenth century. Pascal's father was the tax collector, and the currency system at that time was not a decimal system, which was very cumbersome to calculate.

In order to assist his father, Pascal invented the first calculator that could perform addition and subtraction operations using the principle of gears. Later, the German mathematician Leibniz improved it and invented a calculator that could do multiplication and division. Although the functions of the calculator were improved and refined in the future, the real electric calculator had to wait until 1944 AD to be manufactured.

The first machine that can really be called a computer was born in the United States in 1946, invented by Mao Qili and Eckert, and the name is ENIAC. The computer uses vacuum tubes to process signals, so it's bulky (it takes up a room) and consumes a lot of power (the whole town knows about it, because the lights in every house are dim!). And the memory capacity is very low (only more than 100 words), but it is already a major advance in human technology.

And we usually call this kind of computer that uses a vacuum tube the first generation of computers.

The first generation of computers was the size of two classrooms, which was much different from the size of the personal computers we use today. At that time, the computer parts were vacuum tubes (which can no longer be found) and the archive thing is a punch card, if there is no design concept of predecessors, there is no invention of the computer, so it is a bit difficult to define who invented the computer.

There are two below that I don't know which is correct.

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.

The first computer in the true sense of the word appeared in 1946, in the United States, Eniac.

The world's first electronic computer was named"Enia.

grams"It was successfully developed by Eckert and others at the University of Pennsylvania in the United States in 1946.

On February 15, 1946, the world's first computer was born at Moore College of the University of Pennsylvania in the United States.

The first computer appeared on February 16, 1946, computer (computer), commonly known as computer, is an electronic computer used for high-speed calculation, can perform numerical calculations, and can perform logical calculations, but also has the function of storage 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. A computer that consists of a hardware system and a software system without any software installed is called bare metal.

History of Computer Development:

Around 1946, the first computer was born. It was born in the United States.

The birth of the first generation of computers in 1946 was an important milestone in human history. In the era of mechanization and electrification, people replaced part of their physical labor with machines, and the birth of computers made it possible for people to partially replace people's mental work.

The first computer, ENIAC, was born at the University of Pennsylvania on February 15, 1946.

February 14, 1946, the name is well remembered.
