Presentation
This UC in Computer Networks is an introductory course on Internet computer networking. Its objective is to present all the layers that make up the Internet (Inter-Networks), i.e. Application Layer, Transport Layer, Network Layer and Connection/Physical Layer.
The approach to Programmatic Content is done in a Top-Down way, i.e. starting with an introduction of all layers followed by each one in detail starting with the Application layer.
There is a practical component in this UC, from which the concepts introduced in the theoretical component are demonstrated and trained.
This Curricular Unit thus complements and integrates with the present study cycle, offering a disciplinary component of Computer Networks and their evolution.

Objectives
Objectives
LG1: Know what a network is at a general level. And that the Internet is a network of networks or inter-network. Managing a network of networks that share data without centralized management involves several challenges in terms of management and operation.
LG2: Acquire theoretical and practical knowledge of the various protocols involved in each layer of operation. At the Application Layer, such as HTTP 1.0 and 1.1, DNS, etc. At the Transport layer, protocols such as UDP and TCP and their variants. At the Network layer, the IP protocol, etc. And at the data link layer, knowing what circuit and packet switching is.
LG3: Gain theoretical and practical aptitude for Client-Server communication.
