The device has been used to assist in the calculation for thousands of years. The first is in the form of wood or tally marks to record [7] The Antikythera Mechanism, dating from the beginning of the first century before the Christian era Foreign generally be considered. Analog computer that uses the oldest known. And mechanisms used gear earliest known [8] and the gear can not be compared to its occurrence. Europe until the 16th century, [9] and it did not change until 1645 that the calculator mechanism that has the ability to perform mathematical calculations such as four have been developed [10] computer electronic relays. or valves Began to appear in early 1940 Electromechanical Zuse Z3, completed in 1941, is the world's first programmable computer. And by modern standards As one of the first computers that could be considered a perfect one machine Colossus, was developed during World War II to decode German text, the first electronic digital computer. Although it is programmable It is not used for general purposes. It is designed to run only a single job. It also lacks the ability to store programs in memory as well. Programming Can be done using a plug and switch to change the wiring in [11], the computer that stores programmed digitally sophisticated electronic and accepted the first Manchester Small-Scale Experimental Machine (SSEM), which started the program. In June 21, 1948 [12] , the development of the transistor in 1940 at Bell Laboratories cause the computer to design a new model significantly reduced power consumption. Computer stores programs to be used commercially, the first named Ferranti Mark I covers 4,050 and the power 25 kW compared computers used transistors, first, that was developed at the University of Manchester and. activated in November 1953, only 150 watts of power consumption in the final version of it [13] Information Technology infrastructure. A framework for integrated digital network under running. This infrastructure consists of a data center, computer, computer networking, and database management and supervision system in information technology and the Internet. Infrastructure is the physical hardware that is used in the connection between multiple computers and multiple users. The infrastructure consists of the transmission media, including telephone, cable TV, satellite and antenna. There are multiple routers [14] used to transfer data between transmission technology are different in use for some time. Infrastructure means connecting hardware to software. And does not communicate with computers and other devices that are connected to each other, however, for some people use information technology. Infrastructure is seen as everything that supports the flow and processing of information.
