Module/Subject matter

Module: Mandatory Module of Information Technologies

Subject matter: Network Architecture and Services



This course describes network technologies from the point of view of a complete communications system. This will describe the basic architectures, the fundamental metrics of operation as well as the concept of switching and the role that protocols play in order to guarantee end-to-end communications. LAN will be described as a basic element for the construction of networks, both wired and wireless. The problem of medium access and collisions is studied, analyzing the alternatives to be able to solve them. The need for routing in networks is identified and describes the basic techniques to carry it out, ending with the topic of reliable transport of information in such networks.
