Objectives
THE COURSE PROVIDES THE METHODOLOGICAL AND OPERATIONAL TOOLS FOR A CLEAR UNDERSTANDING OF COMPUTER NETWORKS. SPECIAL ATTENTION IS PAID TO ARCHITECTURAL DESIGN OF NETWORKS AND THEIR BASIC SERVICES TO USERS.

KNOWLEDGE AND UNDERSTANDING
STUDENTS WILL LEARN MODELS USED FOR REPRESENTING COMPUTER NETWORKS, THE MOST RELEVANT NETWORK ARCHITECTURES (BOTH LOCAL AND GEOGRAPHIC), THEIR DESIGN METHODOLOGY, AND THE MOST RELEVANT PROTOCOLS OF INTERNET.

APPLYING KNOWLEDGE AND UNDERSTANDING
DESCRIBE AND DESIGN THE ARCHITECTURE OF A LAN NETWORK AND ITS CONNECTION TO THE INTERNET, AND CONFIGURE BASIC SERVICES THAT IT WILL PROVIDE, BY CONSIDERING ALSO THE TECHNICAL AND LEGAL ASPECTS. THEY WILL ALSO LEARN HOW TO CHOOSE AND DIMENSION ACTIVE NETWORK DEVICES.
Prerequisites
TO SIT FOR THE EXAMINATION IT IS REQUIRED TO HAVE PREVIOUSLY PASSED THE EXAM OF COMPUTER ORGANIZATION.

MOREOVER, BASIC COMPETENCE IN MATHEMATICS AND PROBABILITY IS REQUIRED FOR THE SUCCESSFUL ACHIEVEMENT OF COURSE OBJECTIVES.

COMPULSORY ATTENDANCE:
IN ORDER TO PARTICIPATE TO THE FINAL ASSESSMENT AND TO GAIN THE CREDITS CORRESPONDING TO THE COURSE, THE STUDENT MUST HAVE ATTENDED AT LEAST 70% OF THE HOURS OF ASSISTED TEACHING ACTIVITIES.
Verification of learning
THE FINAL EXAM IS DESIGNED TO EVALUATE AS A WHOLE THE KNOWLEDGE AND UNDERSTANDING OF THE CONCEPTS PRESENTED IN THE COURSE, AND THE ABILITY TO APPLY SUCH KNOWLEDGE IN DESIGNING, CONFIGURING, ADMINISTERING AND ANALYZING SIMPLE NETWORKS.

THE EXAM CONSISTS OF A WRITTEN TEST AND AN ORAL INTERVIEW. THE WRITTEN TEST AIMS TO ASSESS THE KNOWLEDGE AND UNDERSTANDING OF THE MATERIAL PRESENTED IN CLASS AND THE ABILITY OF APPLYING SUCH KNOWLEDGE IN SIMPLE REAL CONTEXTS AND THE CAPACITY OF WRITING A TECHNICAL REPORT. IT REQUIRES TO ANSWER A MULTIPLE CHOICE TEST (50% OF THE EVALUATION) AND SOLVING TYPICAL PROBLEMS PRESENTED IN THE COURSE AND ANSWERING QUESTIONS RELATED TO ARGUMENTS OF THE COURSE (50% OF THE EVALUATION).
THE ORAL INTERVIEW AIMS TO ASSESS THE ACQUIRED KNOWLEDGE AND ABILITY TO UNDERSTANDING AND THE PRESENTATION SKILLS. IT WILL COVER ALL THE TOPICS OF THE COURSE AND ASSESSMENT WILL TAKE INTO ACCOUNT THE KNOWLEDGE DEMONSTRATED BY THE STUDENT AND THE DEGREE OF ITS DEPTH, PROVEN ABILITY TO LEARN, THE QUALITY OF THE PRESENTATION.

IN THE FINAL EVALUATION, EXPRESSED IN THIRTIES, THE EVALUATION OF THE WRITTEN TEST WILL ACCOUNTS FOR 45% WHILE THE ORAL INTERVIEW FOR THE REMAINING 55%. THE CUM LAUDE MAY BE GIVEN TO STUDENTS WHO DEMONSTRATE THAT THEY CAN APPLY THE KNOWLEDGE AUTONOMOUSLY EVEN IN CONTEXTS OTHER THAN THOSE PROPOSED IN THE COURSE.
DURING THE COURSE THERE WILL BE TWO INTERMEDIATE TESTS: THE FIRST ONE APPROXIMATELY IN THE SEVENTH WEEK OF THE COURSE AND THE SECOND AT THE END OF THE COURSE. EACH TEST WILL BE EVALUATED IN THIRTIES AND THE GLOBAL RATE WILL BE GIVEN BY THE AVERAGE OF THE TWO RATES. THE STUDENT THAT WILL OBTAIN A GLOBAL RATE GREATER THAN 16 WILL BE RELIEVED FROM THE WRITTEN TEST. THE EXEMPTION WILL HOLD ONLY FOR THE EXAM SESSION IMMEDIATELY FOLLOWING THE SEMESTER IN WHICH THE COURSE IS TAKEN.
