• he/she knows the protocols used by the most common services, such as WWW, DNS and e-mail;
• she/he learns the mechanisms that drive the operation of the TCP and UDP protocols;
• he/she understands the structure of the IP protocol and the way addressing and sub-networking works;
• she/he understands the Internet routing;
• he/she knows the main technologies for wired and wireless networks (layer 2)

Knowledge and understanding abilities

• he/she is able to identify the components necessary for designing a computer network.

Lessons ex-catedra and discussion of the main topics.
