CompTIA N + is the best certification to deepen the network concept that is widely known. CompTIA N + is highly recommended as a first step professional level certification in the field of networking because many discuss basic concepts. For people who want to focus on the realm of networking really need CompTIA N + concepts to improve their understanding. As knowledge increases, success in demonstrating competence in the field of networking also increases. The main obstacle for people to get a CompTIA N + course is limited time and money. Many courses in the field of networking are offered but with quite high prices. In this study, we developed a CompTIA N + learning model that uses cellular technology and learning feedback methods. By using this technology, people are expected to increase their knowledge of the basic concepts of CompTIA N + anytime and anywhere at very affordable costs. In this module, there are several core competencies that are presented interactively, namely in the field of networking, such as virtual networks, security, and in-depth knowledge of the OSI and TCP / IP models, including IPv6 and cloud. During the learning process, students are under the supervision, evaluation, and supervision of their teacher. The results showed that mobile learning as a learning application that can help vocational students. In this study, feedback from teachers was the most significant influence on student performance.
