OBJECTIVES
In-depth analysis of the lower levels of the OSI reference model: physical, link and network layers. At the physical level we study source coding and compression techniques, as well as channel coding basic techniques. At the link level, we study flow and error control techniques, as well as medium access within local area networks. Third, we analyze network layer, by means of the analysis of X.25 protocol. Finally, we introduce TCP/IP protocol architecture, the most spread in the Internet nowadays.
