Using simulators for teaching computer organization and architecture

An important problem in teaching the subjects of Computer Architecture and Organization (CO&CA) is the linking of the theoretical knowledge with the practical experience. Visualization of different computer hardware architectures with the use of the simulators enhances the learning process among students. Many useful computer simulators can help address this issue by covering various aspects of CO&CA. The programs range from simple simulators to specific teaching tools to advanced and specialized software. We assessed several simulators and selected one that was freely available and that enabled the students to learn the concepts to the fullest. This paper describes our experience of incorporating simulation tools into teaching the CO&CA to information technology and computing students. We demonstrate that the use of simulators helped students understand better how a computer was constructed and how it functioned internally.
