Computer history

Questions related to the invention of the computer can not be answered with one man. This valuable machine consolidate multiple devices created by many people that lead to the creation of this revolutionary machine. This went as far back as several centuries tot he fourth century BC when the abacus was developed by the Babylonians.

There are important concepts that help a computer other occurred in the early days including the revenues from the Arabic numerals and the concept of zero. Development in the 17th century also contributed to it, the development of the first mechanical calculator by Wilhelm Schickard, and Blaise Pascal. Another milestone came in the 19th century, is the plan created by Charles Babbage to create steam-powered "Difference Engine". Although, it did not work was built, the purpose of this tool to calculate astronomical tables. After this, turn to the idea of Babbage Analytical Engine creates basically architectured to solve mathematical problems.

Babbage's writings influenced the idea of Augusta Ada Byron in the Analytical Engine. The writing was clearly outlined several ways in which modern computer is operating. He also discusses the concepts of data analysis such as memory. George Boole, another important thinker, which is responsible for Boolean algebra also need to be credited.

Some computers precursor in the 1940s following the development and use of electricity. Early models such as the computer giant a huge machine that basically do break the code. Other developments in the second half of the 20th century associated with the semiconductor and integrated circuits also contribute to it.

Machine developed in the early 20th century had limited programmability. The concept introduced by John von Neumann, however, has completely changed my memory the computer can store. The operation of modern computers are still influenced by his ideas.

Electronic Delay Storage Automatic Calculator or EDSAC said to be the first computer that can store programs. After this, some developers have contributed to creating various types of computers.

Various significant name began to focus on the early 1970s, including Bill Gates, Steve Jobs, and Steve Woznaik. This inventor has contributed a lot to develop the personal computer in the form of a PC. And in the 1990s, the purchase of personal computers became common. With technological advances, the size of computers has fallen into a way that they can easily be used.
