Diario del corso 2012/13

Lezione per lezione dovrei riuscire a postare qui gli argomenti della lezione e i miei appunti(a distanza di qualche giorno...)

Per favore non scrivete qui sotto così non si interrompe la linea delle lezioni!

se ci sono critiche o suggerimenti mandatemi un messaggio privato!

per ogni lezione metto 2 link per il download, uno è del dsy l'altro è ge.tt un sito di storage molto comodo :-)

INFORMAZIONI SUL CORSO

La cartella Online in cui sono inseriti tutti i file si trova qui

Se invece cercate altri appunti di Reti andate qui
