What is the first computer ever made in history?
Using computer every day would help you update yourself with what is happening in the world. However do you know what the first computer ever made in history is. Just read this article and find the answer.
What is a Computer?
|The very first thing you should consider before delving deeper into a certain topic is to know what topic is about. According to the historyofcomputer.org, in its most basic form, a computer is any device which aids humans in performing various kinds of computations or calculations. In that respect the earliest computer was the abacus, used to perform basic arithmetic operations.|
History and Evolution of Computers
As we know in 19 century, Charles Babbage the famous Mathematics professor had its beginning. He designed Analytical Engine (first mechanical computer) successor of the Difference Engine (automatic mechanical calculator) which is known as a basic framework for today’s computer. It is classified into generations and each generation is the improved and modified version of it.
In 1822, British mathematician and inventor Charles Babbage (1791-1871) built the steam-powered automatic mechanical calculator what he called “Difference Engine” or “Differential Engine”. It was more than simple calculator. Which is capable of computing several set of number and in result it gives hard copies. Ada Lovelace helped Charles Babbage in development of difference engine. It computes polynomial equations and print mathematical tables automatically.
In 1837, Charles Babbage built the first description of a general mechanical computer, which was the successor of the Difference Engine what he called analytical engine, but never completing while Babbage was alive. It was programmed to using integrated memory and punch cards.
In 1991, Henry Babbage, Charles Babbage’s youngest son complete a portion of the machine that perform basic calculations.

Who Invented the First Electronic Digital Computer?
It is worth knowing the father of thư first computer, right? So, as information collected from the ecomputernotes.com, at university of Pennsylvania, J. Presper Eckert and John Mauchly invented ENIAC (Electronic Numerical Integrator and Computer) in November of 1945, it was design and construction was financed by the US military. It was occupied 1800 square feet, 200 kilowatts of electric power, 70,000 resistors, 10,000 capacitors and 18,000 vacuum tubes where used and its weight was almost 50 tones. Although ABC computer was the first digital computer but many still consider the ENIAC was the first digital computer, because it was first operational electronic digital computer. It was used for weather prediction, atomic-energy calculations, thermal ignition, and other scientific uses.
When was the first personal computer invented?
|The first personal computer was introduced in 1975. Ed Robert coined the term “personal computer” and PC appeared in a 3 November 1962 when Altair 8800 was introduced. Early computers generally called microcomputers.|
