ISO/OSI model and data communication by animations

Abstract

The main objective of this work was to develop an interactive environment of teaching and leaming the data communication taking as a base the ISO/OSI model (International Organization for Standardization/Open System Interconnection) and the HFC net (Hybrid Fiber Coaxial). A theoretical framework was elaborated with basic concepts about communication protocols by using the ISO/OSI model and the active and passive elements that take part in the transmission of a message in a HFC net. Animations were made to allow the student study those concepts in an interactive and dynamic way. An interactive section was developed for the self-evaluation of the student. It was considered each of the process that take part in the treatment of the message, as the encapsulation, the codifícation of the digital information and the modulation to an analogue sign, as well as each of the elements that apply a treatment to the message inside the HFC net till it reaches its destination
