摘要:The purpose of this communication is to discuss conceptual links between hypertext links and communication media of knowledge in a learning situation. Indeed, many authors have shown that the process of communicating knowledge, were phenomena of use, social and cultural rights of ICT. We will mobilize to this effect from the work of information science and communication and mana-gement sciences. We seek also to answer some questions: What roles are the links in the communica-tion of knowledge? What influences can these links on the actors of the learning process, or the media of knowledge?
