Date of Computer Science
The history of computer science long before the emergence of modern knowledge branch of computer science that has emerged in the twentieth century and the horizon loomed in previous centuries. The progress of inventions mechanism sports and theories of modern concepts and machines form a major academic field to be the basis for the huge industry spread over the world level
Ancient History:
Old account:
Basic articles: history of computing and chronology of the computerization of the 2400 BC Abacus 1949 was the first known to use tools in the account is believed to have been invented in Babylon circa 2400 BC, and had to body lines drawn in the sand with the development of stones. This was the first and most well-known computer account systems developed so far that preceded the Greek roads by about 2,000 years. Still used with modern design tools counters account so far.
Antikythera Mechanism mechanism believed to be the first analog-to-computer known. [2] It has been designed to calculate astronomical positions. Was discovered in 1901 in the wreck of the ship on the shores of Greece Antikythera Mechanism between the island of Kythira and Crete-old is due to about 100 BC. Technological manufactures did not appear with this kind of complexity until the fourteenth century, when the astronomical clock appeared in Europe. [3]
In the third century AD, two-wheeled vehicle compass works in the history of China emerged was the first pinion mechanism used differential gear that was used then in analog computers. China has also invented (area) more complex counter in about the second century AD, and which is known as the Chinese are many. [Citation needed]
Account devices analog appeared mechanism again after a thousand years in the golden age of Islam and providing examples of devices of this period astronomical calculations tool (Akuatoriom) invented by Ibrahim bin Yahya Al-Zarqali [4], and the astrolabe is a mechanical gear invented by Abu Rayhan Biruni [5] and a observation of celestial bodies which Achterahgabr bin succeeded [6]. Engineers Muslims built a number of automaton including some musical instruments that can be programmed to run different musical styles. These devices were developed at the hands of Banu Musa brothers [7] island [8]. Muslim mathematicians also achieved significant progress in the science of cryptography, such as the development of cryptanalysis and redundancy analysis by Canadian James the son of Isaac. [9]
When it was discovered [Muhammad ibn Musa al-Khwarizmi]] algorithms for the purposes of computing in the early seventeenth century, followed by a period of considerable progress made inventors and scientists in the calculation tools. In Z 632 has Wilhelm Schickard design calculation machine but gave up this project when destroy the prototype, which began construction in a fire in 1624. In 1640 almost, Blaise Pascal has a mathematician French pioneer built the first mechanical collection device [10] on the basis of design Hero of Alexandria described [11] mathematician in the civilization of the Greeks. Then in 1672 invented Gottfried Leibniz gradient calculations completed by the year 1694. Table [12]
It was not any of the old computers in the modern sense Computer It took real progress in mathematics and theory before the possibility of designing modern computers
