La verifica consiste in una esame orale, durante il quale si richiede l'inquadramento di un argomento specifico, la descrizione di un argomento tecnico specifico di un argomento, e lo svolgimento di una attività di laboratorio.
The student will be assessed on his/her demonstrated ability to discuss the main course contents using the appropriate terminology. The discussion may include the demonstration of practical skills, using the laboratory support. The presentation of an oral essay to the colleagues and to the teacher is optional, and complements the assessment.
Methods:
- Final oral exam
- Final essay
- Laboratory practical
Further information:
- Final oral presentation 60% - Participation to seminar, laboratory and seminar presentation 40%.

Utilizzo consapevole di Internet, conoscenza della terminologia correlata, capacità di interagire con professionisti del settore, comprensione delle potenzialità e dei rischi correlati ad Internet, competenza nello operazioni di gestione fondamentali.
Knowledgeable use of the Internet, knowledge of related terminology, ability to interact with specialists, understanding of the the otentials and of the risks correlated with the Internet, competence in carrying out fundamental tasks.
L'esame orale verifica l'efficacia e l'appropriatezza terminologica ed include lo svolgimento di una attività di laboratorio per verificare le capacità pratiche.
The oral examination verifies the efficacy and appropriateness of the terms used and includes the execution of one of the laboratory exercises in order to verify practical skills.
Proprietà d'uso e comprensione della terminologia tecnica.
Correct use and understanding of topic terminology.
Durante la prova orale viene considerata la proprietà del lessico, e vengono proposte situazioni che richiedono semplici estrapolazioni a partire dai contenuti del corso, sopratutto in sede di prova di laboratorio.
During the oral examination we evaluate the terminology used, and we propose situation that require understanding and extrapolation, mainly during the execution of the laboratory activity.
Conoscenza elementare del linguaggio Python e della commandline Unix (Linux).
Basic knowledge of the Python programming language and of Unix commands.
Vengono affiancate lezioni teoriche, pause di riflessione (domande) e attività pratiche (suggerite o svolte in classe), in proporzione percentuale 70+10+20. Le esercitazioni pratiche che non possono essere svolte in classe per motivi di tempo possono essere svolte a casa utilizzando il laboratorio virtualizzato.
