|---|---|
| THE COURSE IS AIMED AT THE ACQUISITION OF KNOWLEDGE ABOUT THE ORGANIZATION, OPERATION AND RESOURCE MANAGEMENT (FOR RESOURCES SUCH AS CPU, MEMORY AND DEVICES) OF A COMPUTER. KNOWLEDGE AND UNDERSTANDING KNOWLEDGE OF THE FUNCTIONS OF A MODERN OPERATING SYSTEM, IN PARTICULAR THE MANAGEMENT OF PROCESSES, MEMORY, PERIPHERALS AND FILES, AND UNDERSTANDING OF BASIC TECHNIQUES FOR THE IMPLEMENTATION OF THESE FUNCTIONS (SCHEDULING ALGORITHMS, MEMORY ALLOCATION, PAGE REPLACEMENT AND FILE SYSTEM), AND OF INTER-PROCESS COMMUNICATION. APPLYING KNOWLEDGE AND UNDERSTANDING UNDERSTAND WHAT HAPPENS INSIDE THE OPERATING SYSTEM DURING THE EXECUTION OF A PROGRAM. USE SYSTEM CALLS OF AN OPERATING SYSTEM FOR PROCESS SYNCHRONIZATION AND MEMORY MANAGEMENT. DEVELOP SIMPLE SHELL SCRIPTS. |
| Prerequisites | |
|---|---|
| THE COURSE REQUIRES THE PROPEDEUTICITY OF THE FONDAMENTI DI PROGRAMMAZIONE (PROGRAMMING FOUNDATIONS) COURSE. FOR AN EFFECTIVE ACHIEVEMENT OF THE COURSE OBJECTIVES, THE KNOWLEDGE ACQUIRED IN THE CALCOLATORI ELETTRONICI (ELECTRONIC COMPUTERS) COURSE IS REQUIRED. |

| Teaching Methods | |
|---|---|
| THE COURSE INCLUDES FRONTAL LECTURES AND LABORATORY EXERCITATIONS. IN LABORATORY EXERCITATIONS, STUDENTS ARE REQUIRED TO WRITE C PROGRAMS AND SHELL SCRIPTS USING THE LINUX OPERATING SYSTEM. COURSE ATTENDANCE IS COMPULSORY. TO ACCESS THE FINAL EXAM, STUDENTS MUST HAVE ATTENDED AT LEAST 70% OF THE TEACHING HOURS. |
| Verification of learning | |
|---|---|
| THE EXAM IS COMPOSED OF A WRITTEN TEST AND AN ORAL INTERVIEW, GRADED IN 30-THS. TO ACCESS THE ORAL INTERVIEW, THE STUDENT MUST PASS THE WRITTEN TEST WITH AT LEAST 18/30. DURING THE COURSE, A PARTIAL WRITTEN TEST (PROVA IN ITINERE) WILL BE HELD, THAT, IF PASSED, EXONERATES THE STUDENTS FROM A PART OF THE FINAL WRITTEN TEST. THE WRITTEN TEST IS AIMED AT EVALUATING THE UNDERSTANDING OF THE MAIN MECHANISMS FOR THE MANAGEMENT OF PROCESSES, MEMORY AND FILES, AND THE ABILITY TO WRITE SIMPLE C PROGRAMS USING THE SYSTEM CALLS AND SHELL SCRIPTS FOR THE BASH SHELL. THE ORAL INTERVIEW IS AIMED AT EVALUATING THE LEVEL OF THEORETICAL KNOWLEDGE, THE AUTONOMY OF ANALYSIS AND JUDGEMENT AND THE EXPOSITION ABILITY OF THE STUDENT. THE MINIMUM PASSING GRADE (18) IS ATTRIBUTED WHEN THE STUDENT HAS A FRAGMENTARY KNOWLEDGE OF THE THEORETICAL CONTENTS AND A LIMITED ABILITY OF APPLYING THE ACQUIRED KNOWLEDGE. THE MAXIMUM GRADE (30) IS ATTRIBUTED WHEN THE STUDENT SHOWS A COMPLETE KNOWLEDGE OF THE THERORETICAL ASPECTS AND A SIGNIFICANT CAPABILITY OF APPLYING THE KNOWLEDGE TO SOLVE PROBLEMS SIMILAR TO THE ONES PRESENTED IN THE COURSE. THE “LODE” (HONORS) IS AWARDED WHEN THE STUDENT SHOWS A DEEP KNOWLEDGE AND UNDERSTANDING OF THE THEORETICAL ASPECTS, AN EXCELLENT LANGUAGE PROPRIETY AND A SIGNIFICANT ABILITY OF AUTONOMOUS ELABORATION IN THE APPLICATION OF THE ACQUIRED KNOWLEDGE ALSO TO CONTEXTS DIFFERING FROM THE ONES PRESENTED IN THE COURSE. |
