ARCHITETTURA INTERNET - channel 1

This unit introduces to the knowledge of the protocols of the Internet. The student will understand how the Internet works and, in particular:

• he/she knows 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).

At the end of the course the student will is able to identify the components necessary for designing a computer network.
