Data osi model

OSI-modellen, även känd under sitt standardnummer ISO/IEC 7498, är en konceptuell modell för datorkommunikation i 7 lager. Modellen är det mest kända resultatet av projektet Open Systems Interconnection, som togs fram på initiativ av internationella teleunionen ITU och Internationella StandardiseringsOrganisationen.
