Technologies related to computer networks have been expanding rapidly. Computer networks need to be understood theoretically as well as practically, hence network simulation tools should be recommended to address this challenge. Students may use networking simulation tools to build, tune, and evaluate networks while strengthening their understanding of networking theory.On the market, there are several network simulation programs that enable users to simulate LANs, MANs, and WANs such as Ns3, OPNET and Packet Tracer.The objective of this research is to investigate the effectiveness of utilizing Cisco Packet Tracer as an educational tool. In addition, this paper aims to study what extend Packet tracer tool enhance student's understanding of computer networks theoretically and practically. Respondents of the study were the 41 second and fourth year students from Computer Science department at University of Tobruk who took Network course. The questionnaires were used as the research instruments in this stud. Data collected from questionnaire was analyzed using software program The Statistical Package for the Social Sciences (SPSS). In brief, Cisco Packet Tracer has been provena powerful simulation and visualization tool for aiding in theteaching and learning of Computer Networking courses.
