It is a hard to question when was the computer invented it is actually started hundreds of years. But people think that it was invented by Charles Babbage between 1833 and 1871. Who invented computers all the credit can go to Sir Charles Babbage, So we are just willing to know about this query here in this article I will discuss the complete detailed history of computer. I will go with answering to you people this question when was the computer invented with complete date history. 

 I will discuss these topics here:

  •  History of Computer,
  •  When was the computer invented? 
  • Who invented computers with dates and times
  • The history of computers?

These are some subtopics that will be discussed in this article.

Abacus

The earliest device that qualifies as a computer is that the abocus. The abacus was invented 5,000 years ago in Asia Minor and continues to be in use today. This device allows users to calculate, by sliding beads arranged on a rack.

In 1642 Blaise Pascal

The 18 years old son of a French taxman, invented a numerical 1.2.2 mathematician (1623-1662) wheel calculator to assist his father in the calculation. This device was called "Pascaline" and was only ready to add two numbers.

Barron Gottfried Wilhelms Von Leibniz (1646-1716)  

In 1961, a German philosopher and mathematician Barron Gottfried Wilhelm. Von Leibniz made some improvements in Pascal's machine. He added the feature of multiplication and division. The machine was able to perform these operations by using repeated additions and subtractions. Leibniz's mechanical multiplier worked by a system of gears and dials.

Charles Xavier Thomas De Colmar (1785-1870)

 Charles Xavier Thomas De Colmar, a Frenchman, invented the machine in 1820 that would perform the four basic arithmetic functions. This machine was called an Arithmometer.

 Charles Babbage (1791-1871)

An English mathematician, Professor Charles Babbage made a "Difference Engine" in 1833, which was powered by steam to resolve mathematical equations. After ten years, in 1842, he made a "Analytical Engine". This analytical engine could add, subtract, multiply and divide in automatic sequence at a rate of 60 additions per second. general-purpose computer named

 Joseph Marie Jacquard (1752-1834)

French silk weaver and inventor Joseph Maric Jacquard invented the loom. Jacquard's loom was In 1801 a controlled by the recorded patterns of holes in an exceeding string of cards.

 Lady Ada Augusta Lovelace (1816-1852)

 Lady Ada Augusta Lovelace was an English woman. Charles Babbage was her ideal. She studied and translated his works, adding her own extensive footnotes. She was called as a primary programmer due to her suggestions that punched cands might be prepared to instruct Babbage's engine to repeat certain operations,

Herman Hollerith (1862-1929)

In 1890, an American inventor discoverer applied the concept of punch boards within the variety of punch cards in computers for input and output. He invented a card tabulating the machine.

 Dr. John V. Atanasoff and Clifford E. Berry (1903-1995)

In 1939, Dr. John V. Atanasoff, a professor at Iowa State University, and this collegian Clifford E. Berry assembled a prototype of ABC (Atanasoff and Berry Computer) to save lots of time for calculation, A working model of ABC was finished in 1942. He made a machine that applied mathematical logic to computer circuitry,

 Boole (1815-1864)

George Boole clarified the binary number system of algebra, which stated that any mathematical equation may be stated simply as either true or false.

 John Napier (1815-1864)

Another manual calculating device was John Napier's bone or cardboard multiplication calculator. it had been designed within the early 17th century and its upgraded version was in use even around 1890.

The steps of technological differences are called generations. In 1941 German engineers had developed a computer named Z3 to style airplanes and missiles. In 1943 nation made a computer named Colossus to interrupt secret codes during war II. 

Mark 1

In 1944, an American Howard A. Aiken, Professor of Haryant Unversity, made the simplest electromechanical computer. Mark 1. it had been about $1 feet long and feet high slow machine. Over 1000 electrical actuated switches were wont to control its operation

ENIAC (Electronic Numerical Integrator and Computer)

In 1946, ENIAC (Electronic Numerical Integrator and Computer) was made by Dr. John W. Mauchly collaborated with J. Presper Eckert. Jr. at the University of Pennsylvania. it had been 1000 times faster than Mark I. It occupied 15000 square feet of floor spacing and weighs 30 tons. The ENIAC could do 5000 additions per minute.

EDVAC (Electronic Discrete Variable Automatic Computer)

John Neumann designed the EDVAC (Electronic Discrete Variable Automatic Computer). The key element of the Neumann architecture was the central processing unit, which allowed all computer functions to be coordinated in binary form (0 & 1).

UNIVAC-1 (Universal Automatic Computer UNIVAC-1)

1951, UNIVAC-1 (Universal Automatic Computer UNIVAC-1) built by Dr. Mauchly and Eckert for Remington Rand Corporation, and installed within the U.S. Bureau of the Census, became one in all the primary commercially available computers.
