Learning objectives
Knowledge and understanding - By means of lectures attended in the context of the course, the student will learn the major Web technologies and the JavaScript programming language. The student will also learn principles and technologies of service oriented architectures. The student will acquire knowledge about the most important peer-to-peer and blockchain architectures and protocols. Finally, the student will learn the basic principles of cryptography and secure communication protocols.
Applying knowledge and understanding - By means of lectures and practical activities in the context of the course, the student will learn how to apply the acquired knowledge in a real design environment. In particular, the student will learn to: implement dynamic Web pages, implement Web applications, design and implement Web services, design and implement peer-to-peer applications, with particular attention to security issues.
Making Judgements - The student will be able understand and critically evaluate the main types of Internet technologies.
Communication Skills - By means of the lectures and the discussions with the teacher, the student will acquire the specific lexicon related to Internet technologies. It is expected that, at the end of the course, the student will be able to transmit, both in oral and written form, the main topics of the course, like ideas, engineering problems and related solutions.
Learning skills - The student that will attend the course will be able to improve its knowledge about Internet technologies, by autonomously referring to specialized books, scientific publications, also beyond the topics presented by the teacher during the lectures, in order to effectively face the entry into employment and undertake further training paths.

Teaching methods
The lectures will be given in presence.
The teacher will illustrate the course topics by means of slides. Some hours will be devoted to the practice of software development. Teaching materials (including slides, lecture notes, source code, scientific articles) will be uploaded on the Elly platform. Students that won't attend the lectures are invited to check the available teaching materials and recommendations provided by the teacher through the Elly platform.
Assessment methods and criteria
The learning evaluation consists of two or three moments (depending on the version of the course, providing 6 or 9 credits): 1) a written exam lasting 1 hour, with open questions related to the parts 2-3-4 of the course; 2) a written exam lasting 1 hour, with open questions related to the cybersecurity part of the course; 3) a software development project based on the technologies illustrated within the course; it is mandatory to write a short report and to make an oral presentation of the work done. Each written exam is evaluated on a 0-30 scale. The project is evaluated on a 0-30 scale. The final grade is the average of the partial grades.
There will be a midterm written exam equivalent to moment 2) of the learning evaluation, thus related the cybersecurity part of the course. The student that gets at a mark greater or equal than 18 in the midterm written exam is exempted from moment 2) of the learning evaluation.
