KNOWLEDGE AND COMPREHENSION
The course of Elements of Informatics provides students with basic knowledges on the use of modern calculators, to understand how they work and are organized, and the bases for computer programming. The knowledge about how are represented and stored in computers the numbers: integers, reals, complex, alphanumerical data and other data types. Knowledges on the internal structure and architecture of calculators and of Internet and how data storage and data transmission work. Students will learn how to manage linux/unix environment and the bases of C programming.
KNOWLEDGE AND COMPREHENSION APPLIED (Abilities)
The course is oriented to applications. Students have to solve problems through the usage of computers and programming languages, the bases of C programming and of Unix environment, to use common algorithms.
Exercises are presented in order to sustain autonomy in judgment. Students should autonomously choose the most appropriate tools for problem solving.
Students will learn the basis of the informatics language.
Student will be able to tackle further courses requiring informatics and programming knowledges. They will learn autonomous problem solving for elementary programming, for boolean logic, for binary conversion.
They will know how modern computers work.
They will learn how to analyze simple programs written in C.
-Knowledge of computer and operating systems at user level.
-Good knowledge and skills in logics and mathematics at high school level.
-Knowledge of basic operation on numbers
-Computer architecture, storage memories, logical circuits, algorithms, operating systems, Unix, Linux. Boolean Logic. Structure of the RAM memories, Hard Disk, memories.
-Linux environment, directory structure, terminal and command line, man, cat, cd, pwd, ls, cp, mv, rm, history, clear cat, more, less, head, tail, grep.
Command options. Pipe.
-Numbering systems: decimal, binary, exadecimal, conversions between systems and their mathematics. Information coding. Characters, reals, integer types. Images and sounds.
Basics of computer networks
-C programming, variables, types, declarations, initialization, constants. Operators: arithmetical and logical, conditional, console I/O: printf, scanf, cout, cin. Type-specifier, escape sequences. Control structures, if, if-else, if-else-if, cycles, iterations, for, while, do-while. Arrays, structures and arrays of structures, functions, parameters, references, function prototypes. Pointers, declaration, operators & and *. Pointers and arrays. File I/O, opening and closing a file, fopen, fclose, fprintf, fscanf.
The course lats 64 hours partitioned in frontal teaching and exercises with theoretical sessions and practical sessions and in laboratory sessions on PC with exercises.
At the beginning of the course a calendar will be defined for laboratory sessions whose attendance is important in order to acquire the abilities needed to pass the course.
For this a.a. the difficulties associated with the Covid019 epidemic will be taken into account according to the following:
"In accordance with the Manifesto of Studies for the academic year 2021-22, e
compatibly with the circumstances due to the situation
pandemic, teaching will be delivered mainly face to face, integrated and
"augmented" with online strategies, in order to guarantee it
fruition in an innovative and inclusive way. "
The laboratory exercises can be carried out through forms of remote interaction with the available IT supports. On the basis of the contextual conditions linked to the Covid-19 pandemic, shifts and / or online replacement activities may be envisaged.
Verification of learning
The purpose of the exam prove is to verify the level to which the formative objectives have been reached.
The exam consists of two written/laboratory parts on the course topics, on the usage of PC and Linux and on programming which will last 2 or 3 hours in total.
In general the Moodle platform will be used for the proves.
Eventually the written prove will be done using a PC in the lab. In the proves the students should pass with a minimum mark of 16/30. The final mark will be the average of the two proves, which cannot be lower than 18, integrated eventually by an oral prove, according to the criteria reported below.
The final mark, eventually after an integrative oral exam, will be given according to the following rules:
Not sufficient: the student does not know many of the fundamental constructs of the discipline.
18-24: the student knows part of the topics, understands and manages the basic of the discipline, partially completes the assigned laboratory tasks.
25-28: the student knows all the topics, understands and manages the discipline, performs the laboratory tasks.
29-30: the student knows very well all the topics, uses a correct discipline language, explains the acquired notions.
30 and laude: the student perfectly knows all the topics and manages the discipline in depth, correctly uses the technical language, brightly solves the assigned tasks.
Following the provisions related to the Covid-19 epidemic, these examination methods may be replaced by different verification methods, for example: individual or group work (term papers), oral interviews, remote written tests using computer aids (moodle, Teams, etc.),
During the course the students will be provided with
didactic material, which can be downloaded from the course web-site or from the Teams platform, through pdf pr ppt files, or files
in C language.
