3 Data Link Layer - Error correction, error detection, and flow control,
4 Medium Access Control sublayer - Ethernet, hubs and switches
5 Network layer
routing - algorithms, routing in the Internet, RIP, OSPF, BGP,
IP addressing - IPv4, IPv6, DHCP, NAT
6 Transport layer - UDP, TCP, flow and congestion control
7 Network services: Address assignment (DHCP), Address resolution (ARP), Domain name DNS
8 Security: Cryptography, SSL, IPsec, WEP, firewalls

Teaching Methods
the teaching methodologies include:
All resources are provided in an e-learning digital platform (e.g. Moodle);
The relevant resources are provided previously to each presencial session;
Practical example presentations, demos, and problem solving for each presented concept;
Presentation and submission of exercises in the e-learning digital platform;
Concept presentation is oriented around proposed projects;
Session with Invited speaker from a private company concerning one of the topics and showing the practical application of computer networks.
Evaluation:
A - two to four written tests and/or final written exam;
B - resolution of problems and development of a small individual or group project, including a presentation and discussion of the proposed solutions;
The final grade is the weighted average of the two components, where each component as a minimum of 40% of weight.
