The computer networking course is usually taught in a mixed mode, which includes a lecture and a practical lesson, and in addition to a full-time theoretical lesson, students must take practical classes to evaluate technologies and content. Nevertheless, the abstractions of the computer networking course, such as the multilevel complexity of the TCP/IP network, the connection and configuration of client and server infrastructure, as well as the differences in static and dynamic configuration of IP addresses, set students a huge task to understand and master the basic concept of computer networking technologies. Thus, the approach based on the use of computer network modeling and visualization tools when teaching the computer networks course is considered useful for teachers and students. In this study, Cisco Packet Tracer computer network simulation software was used in the Computer Networking Course (KJ2212). Students (N=55) got acquainted with the Cisco Packet Tracer program, on the basis of which they developed a global network (WAN) consisting of personal computer (PC) configuration operations, servers and switches in accordance with the Cisco standard. Subsequently, with the help of a survey, the opinions of students and their understanding of the effectiveness of Cisco packet Tracer in teaching computer networks were studied. All feedback was statistically studied using SPSS 16.0. From the analysis of descriptive results, all students agreed that Cisco Packet Tracer successfully helped them understand several key concepts of computer networks and at the same time eliminate some abstractions they encountered during the course (N=32: totally agree; N=23: I agree). Cisco Packet Tracer has established itself as a modeling and visualization tool as an effective software that supports computer networking course training.networking course training.
