User is now possible to see the world in a different way, to achieve new goals, which were once impossible, and to control the world us. Computers are efficient tools in processing data into useful information. These are essential tools in almost every field of research and applied technology because of their capabilities. The impact of computer varies in different applications. User can perform logical operations on texts as well as on numbers and symbols. User is made possible to process data user great speed, accuracy, and reliability. Holoein (1986) says that “almost every one in developed nations of the world are at least partially aware of the influential role played by the computer today”. User is implemented to every type of organization in order to achieve computer advantage. O’Brien (1990) states that the management of rapidly changing technology is important to any organization.

Developments will continue to have a major impact on the operations, costs, and management work and computerization of many organizations. Computer system has played an important role in monitoring the volume of work, which takes place everyday in almost all offices. This easy way of doing everything, such as keeping and retrieving records would not be possible output appropriate information system and technology that will go user user. Computer systems have the bigger advantage to acquire a high level of system knowledge that will serve as a source of information in the modification of a system that used in specific task which lies in the amount of information a person will be able to extract. Software systems maintain enormous amounts of data and contain functional tasks that most users realize. The
