Teaching Methods
TEACHING METHODS: LECTURES, GUIDED EXERCISES AND LABS. GUIDED TOURS TO NETWORK COMPANIES. THE COURSE PROVIDES THE ASSIGNMENT TO EACH STUDENT OF A PROJECT CONCERNING THE DESIGN OF A LOCAL NETWORK AND ITS CONNECTION TO THE INTERNET.
Verification of learning
THE ACHIEVEMENT OF THE TEACHING OBJECTIVES IS CERTIFIED
BY PASSING AN EXAMINATION WITH AN EVALUATION IN THIRTIETHS (THE
MINIMUM LEVEL OF EXCEEDANCE IS '18' AND THE MAXIMUM IS '30 E'.
LODE'), WHICH PROVIDES FOR A SINGLE ORAL TEST, OF AN INDICATIVE DURATION
AVERAGE OF 60 MINUTES, AND AIMED AT: 1) VERIFY THE LEARNING
OF THE TOPICS COVERED IN THE THEORY HOURS; 2) VERIFY THE GOOD
OUTCOME OF THE GROUP PROJECT CARRIED OUT ON THE TOPIC ASSIGNED BY THE
3) TO VERIFY THE ABILITY OF THE SUBJECTS TO BE PRESENTED
4) TO VERIFY THE AUTONOMY OF JUDGEMENT IN PROPOSING
THE MOST APPROPRIATE APPROACH TO ARGUE WHAT IS REQUIRED.

MORE IN DETAIL, THE ORAL TEST CONSISTS OF TWO QUESTIONS: THE FIRST IS
CONCERNING THE PROJECT CARRIED OUT (EXAMPLE: GENERAL DESCRIPTION,
RESULTS ACHIEVED, METHODS USED AND IMPLEMENTATION SOLUTIONS
CHOICES FOR SPECIFIC PARTS OF THE PROJECT) AND THE SECOND ON ONE OF THE TOPICS
THE COURSE IS DESIGNED TO BE USED IN FRONTAL LESSONS (E.G. TYPE AND ARCHITECTURE OF COMPUTER NETWORKS);
NETWORK PROTOCOLS, DESIGN AND IMPLEMENTATION OF A DISTRIBUTED APPLICATION IN A WEB ENVIRONMENT).

IN ORDER TO PASS THE EXAM IT IS NECESSARY TO REACH A SUFFICIENT LEVEL
BOTH IN THE VERIFICATION OF THE LEARNING OF THE TOPICS DEALT WITH IN THE
HOURS OF THEORY THAT IN THE VERIFICATION (REALIZATION AND CAPACITY OF
DESCRIPTION) OF THE LABORATORY PROJECT ASSIGNED.

THE STUDENT REACHES THE LEVEL OF EXCELLENCE IF HE/SHE DEMONSTRATES THE ABILITY TO
TO MAKE LINKS BETWEEN THE THEORETICAL TOPICS COVERED AND
DEMONSTRATES FULL MASTERY OF THE ACTIVITIES CARRIED OUT DURING THE PROJECT
OF LABORATORY REALIZED.
