who invented the computer

Who invented the computer? Charles Babbage is one of the scientists in the world, which has a lot to work on human life, especially the computer field. Totalizer (Difference Engine no.1) which was discovered by Charles Babbage (1791-1871) was one of the most famous icon in the history of computers and is the first automatic calculator. Babbage also famous with the nickname of the father of the computer. The Charles Babbage Foundation bears his name to honor his contributions to the world of computers.

Charles Babbage was born in what is now known as Southwark, London, December 26, 1791, son of Benjamin Babbage, a Banker. The surplus in mathematics is striking. When entering Trinity College in Cambridge in 1811, he found that mathematical ability is much better, even than his own tutor.

At the age of 20 annual Babbage worked as an expert in the field of mathematics, especially calculus functions. In 1816, he was elected as a member of the "Royal Society" (an organization of independent academic science and the United Kingdom, is still active today) and play an important role in the foundation's "Astronomical Society" (organization of Astronomy and Geophysics British highway, was still active until now) in the year 1820. At this time became interested in Babbage's calculating machine, which continues until the end.

Year 1821 Babbage Difference Engine to create a machine that can sort the table Mathematics. When the machine is complete in 1832, Babbage got the idea about a better engine, which will be able to finish not just one type but different types of arithmetic operations. This machine is called the Analytical Engine (1856), which is intended as a general symbol machine, and has some characteristics of the modern computer. Among them is the use of punched cards, a memory unit to enter numbers, and various other computer elements.



Babbage's work is less well known until one day he met with Ada, Countess of Lovelace, daughter of Lord Byron. Babbage's first meeting was at an event on June 6, 1833. Nine years later, Luigi Federico Manabrea (an engineer from Italy) explains how the Analytical Engine. This work was later translated and added notes by Ada Lovelace in 1843. Starting from the moment people begin to recognize the work of Charles Babbage.

But alas, only a few remaining relics of the Difference Engine prototype machine, because the machine needs exceed the available technology at that time. And even though Babbage's work appreciated by the various institutions of science, the British government suspended funding for the Difference Engine in 1832, and finally stopped completely in 1842. Similarly, the Difference Engine is only realized in the plan and design.

In 1828 until 1839, Babbage title got the Lucasian chair of mathematics (the title of professor of mathematics most prestigious in the world) from the University of Cambridge. In addition to calculating machines, Babbage also provides various other contributions. Among them create a modern postal system in England, the first insurance tables set with reliable, find the locomotive cowcather (triangle-shaped structure at the front of the train, which can clean the tracks of the disturbance) and several others. In addition Babbage also contribute ideas in economics and politics.

Charles Babbage was also an expert who had solved cryptanalysis Vigenere cipher (polyalphabet cipher). His brilliance was in fact already had since 1854, after he had defeated the challenge to solve cipher Thwaites. However, this discovery was not published that he had discovered in the 20th century when the experts examine notes-notes (text, notes) Babbage.

Behind all his success, failure in making the calculation engine and the failure of government assistance to him, left Babbage in disappointment and sadness at the end of his life. Babbage died at his home in London on October 18, 1871.
