IN3260 – Prosjektoppgave i Informatikk: datakommunikasjon § Drive med noe praktisk innen nettverk − Tilknyttet forskning; spennende ting som tas i bruk! § Personlig veiledning; tenk “bacheloroppgave” (Mini-masteroppgave) − Dermed blir det enklere å komme i gang med den riktige masteroppgaven senere! (faglig stil, verktøy som LaTeX, ..) § Det begynner med et fellesmøte hvor vi presenterer oppgaver som kan velges... men først: meld deg på! § Mer informasjon: https://www.uio.no/studier/emner/matnat/ifi/IN3260/ University of Oslo IN2140 – Introduction to operating systems and data communication
