  2. 2. Definizione di informatica Deriva da informazione + automatica e si riferisce alla gestione automatica dell’informazione mediante un computer. E’ la scienza che si occupa della conservazione, dell’elaborazione e della rappresentazione dell’informazione. Il computer è una macchina capace di compiere operazioni logiche attraverso le quali conservare, elaborare e rappresentare l’informazione.martedì 21 dicembre 2010
  3. 3. Storia dell’informatica I ORIGINI • Charles Babbage (1791 - 1871) Macchina differenziale (equazioni polinomiali, non realizzabile all’epoca) Macchina analitica (programmabile per eseguire ogni tipo di calcolo, non realizzata all’epoca)martedì 21 dicembre 2010
  4. 4. Storia dell’informatica II ORIGINI • Augusta Ada Byron (1815 - 1852) Prima programmatrice della storia dell’informatica, scrisse il primo programma per la macchina analitica, il programma calcolava i numeri di Bernuolli (somme di potenze di interi successivi)martedì 21 dicembre 2010
  5. 5. Storia dell’informatica III SECONDA META’ DELL’OTTOCENTO • Marchingegni basati sulla tecnica degli “ossicini di Nepero” (impiego di bastoncini numerati per eseguire moltiplicazioni e divisioni) (rullo cilindrico di Tacher, tabulatrice di Herman Hollerith, ...) INIZIO NOVECENTO • Lo sviluppo economico porta alla diffusione delle macchine meccanografiche, Hollerith fonda l’IBM (International Business Machine)martedì 21 dicembre 2010

  13. 13. Storia dell’informatica XI • LEGGE DI MOORE e il numero di Le prestazioni dei processori, transistor ad esso relativo, raddoppiano ogni 18 mesi Maggio 1997 Pentium II a 300 Mhz Novembre 2000 Pentium 4 a 1,5 Ghz (42 mesi, prestazioni quintuplicate)martedì 21 dicembre 2010
  14. 14. Storia dell’informatica XII Gennaio 2006 esce il laptop “MacBook Pro” con processore Intel Yonah Core Duo a 2,16 Ghz. 23 Ottobre 2006 esce la nuova serie di laptop “MacBook Pro” con processore Intel Merom Core Duo a 2,16 Ghz con un incremento di prestazioni del 39% rispetto alla linea precedente. Pari velocità di calcolo, incremento delle prestazioni. http://www.macitynet.it/macprof/aA26028/index.shtml http://www.macitynet.it/ilmiomac/aA26020/index.shtmlmartedì 21 dicembre 2010

La società dell’informazione Modello fordista basato sulla catena di montaggio, prevedeva uno sviluppo illimitato. 1972 Crisi petrolifera dello Yomkippur Modello Toyota basato sull’abbattimento dei costi di produzione morti, prevede il concetto di “just in time” (produrre il necessario quando è necessario in modo da abbattere i costi di magazzino) Nel paradigma economico attuale l’informazione è una merce come le altre, e l’informatica è quello ciò che permette di veicolare questa merce.martedì 21 dicembre 2010
