Beginning of the computer
Beginning of the computer that is actually formed by seoarang British mathematics professor, Charles Babbage (1791-1871). 1812, Babbage noticed natural fit between the mechanical and mathematical machinery: mechanical machines are very good at doing the same tasks repeatedly without mistake; mediocre mathematician requires a simple repetition of a certain steps. These problems grow up to put the machine kemudain mechanics as a tool to answer the needs of mechanics. Babbage’s first attempt to address this problem emerged in 1822 when he proposed a machine to perform calculations differensil equation. The machine was called the Differential Engine. Using steam, the machine can store programs and can perform calculations and print the results automatically. After working with Differential Machine for ten years, Babbage was suddenly inspired to start making general-purpose computer first, called the Analytical Engine.
Further development, emerged what is called the Electronic Numerical Integrator and Computer (ENIAC), which is made by the cooperation between the governments of the United States and the University of Pennsylvania. Consisting of 18,000 vacuum tubes, 70,000 resistors and 5 million soldered joints, the computer is a machine that consumes enormous power of 160kW. This computer was designed by John Presper Eckert (1919-1995) and John W. Mauchly (1907-1980), ENIAC is a versatile computer (general-purpose computer) that became the forerunner of PCs that exist today.
Early development of the Intenet
At first the Internet is a computer network established by the U.S. Department of Defense in 1969, through a project called ARPANET ARPA (Advanced Research Project Agency Network). The initial purpose of the construction project is for military purposes. At that time the United States Department of Defense (U.S. Department of Defense) create a system of computer networks that are spread by linking computers in areas vital to address the problem in case of nuclear attack and to avoid any centralized information, which in case of war can be easily destroyed.
