The device has been used to aid in calculating the thousands and thousands of years ago. For the first time, in the form of nut wood or TIO to save the count [7] Antikythera mechanism foreseen from the beginning of the 20th century, one of the first khrit tasakrat generally is considered as an analogue computer which used a mechanism as the oldest known and mechanisms that use the gear as the oldest known [8] Phuong t device can calibrate not occurred in Europe until the 16th century [9] and it didn't change until the year 1645 that the first mechanism calculator has the ability to perform basic math calculations, all four have been developed [10]Electronic computers, which use relays or valves began to appear early in the year 1940, Zuse Z3 konfai blue, was completed in 1941, is a computer program, the world's first State-of-the-art standards and is one of the first machines that could be considered as a traditional.Perfect ongkhomphiotoe one Colossus machines, was developed during the second world war to decode German messages., as the first digital electronic computer, even if it is a program, it is not used for general purposes, it is designed to work.P. one Yong It also lacked the ability to store it in memory as well. Programming can be done by using plug-ins and switches to change the internal light wiring [11] A computer that stores the program has state-of-the-art digital electronics and accepted the Manchester Small-Scale Experimental Machine was first (SSEM) which started the first program on June 21 1948 [12]The development of the transistor in the late 1940 at Bell Laboratories to design a new version of the computer, the power consumption significantly reduced. A computer that stores the program. the first commercial name Ferranti Mark I consists of. Valve-4050 and 25 kW power consumption when comparing the first transistor-based computer, which was developed at the University of Manchester and in November 1953, the power consumption is 150 Watts in the final version of it [13]Information technology infrastructure as an integrated framework under the digital network is working. This infrastructure consists of a Data centers, computers, computer networks, database management, equipment and supervision system.In information technology and the Internet. A physical hardware infrastructure that is used to connect between multiple computers and multiple users. The infrastructure consists of the transmission media, including telephone lines, cable tv, satellite and antenna and also has multiple routers [14] is used to transfer information between several transmission technologies are different.In some applications. Infrastructure refers to the hardware and software connections not to communicate with other computers and devices that are connected. However, for some users, information technology Infrastructure is seen as everything that supports the flow and processing of data.
