Abstract
Computer networks are needed in various fields, including in schools. Computer networks are needed for the efficiency and effectiveness of cost and equipment use. SMK Negeri 1 Lintong Ni Huta, one of the State Vocational Schools in Humbang Hasudutan Regency, as an IT-based Vocational School or one that manages the RPL and TKJ Departments, should utilize Computer Networks as a means and infrastructure in the teaching and learning process and services to students. However, in reality, this has not been implemented due to a lack of understanding and not understanding the function and advantages of a computer network. That is the reason why it is important to carry out this community service at SMK Negeri 1 Lintong Ni Huta.
