The history of the modern computer is started from two different technologies, including automatic calculation. With a programmable calculator. (Referred to as a way to work and customize it), but not explicit that the technology of any kind occurs first. This is partly because the type is not consistent. Some equipment is also important to mention Such as a mechanical tool to calculate some of the most successful and widely used for many centuries before the electronic calculator.
The abacus of the people of Sumer were built around 2500 BC to beat the competition in the desktop calculator on since 1946 in Japan. Later in the decade 1620 Christ the invention of the slide hole. The spacecraft was brought up in the mission of Apollo to 5 times as well as time to explore the moon with. It is also available. To predict the positions of stars (Astrolabe) and the mechanism of the Hunter's comments. A calculator. (Computer) with the ancient Greek astronomy is built around 80 BC [9] that the system is programmed to occur. Hee, Robert Alexander of Alexandria (c.10-70 AD) Greek mathematician who created a machine that contains the theater. The show runs 10 minutes long, with a rope and the engine cylinder block, brick complex. Which can decide whether any parts of the mechanism used in any scene, and when.
Around the late 10th century Pope Sylvester in the second, a French priest. The drawer contains the type of equipment to answer that question yes or no when asked. (In binary), which made it back from the Moors in Spain in the 13th century, St. Albert the Bear and Tu Yu and Roger Bacon, English philosopher. Has created a robot, an Android (android) I have not developed any further (Saint Albert Bear Herodotus was Yu's complaint was that he was wasting time going back 40 years to life on St. Thomas. The Aquinas was on this machine and destroy it.)
In 1642 the Renaissance. With the invention of the calculating machine of Pascal is a mechanical calculator. The device can be calculated using the mathematical operations without relying on human intelligence. Mechanical calculations is also the foundation for the development of computers in the first two attempts to develop a high performance computing and flexible. This theory, which was built by Charles Babbage, and has been developed at a later time. Lead to the development of mainframe computers. (Large computer) in Christ and in the 1960s, Intel was able to devise. Microprocessors. This is a major change in the origin of the personal computer. And is the heart of a computer system without taking into account the size and purpose [1 occur by chance during the development of e-Business in the Community to develop a direct successor of the mechanical calculator.
