This paper describes the developed technology for using the Raspberry Pi micro-computer to teach practical skills on computer networks and operating systems. The effectiveness of acquiring skills using the proposed technology is due to the fact that it allows organizing the workshops with personal support with the necessary special tools. The paper presents a largely implemented project on an initiative basis, preceding the work on commercialization of the described results. In the present work a full detailed content of the steps for implementation and subsequent commercialization of the solutions presented in the project is given. There was assembled a prototype of the hardware-software device. There were developed individual training kit...
