<p id="wx51">Il <b id="wx52">livello applicazioni</b> è il settimo ed ultimo livello del <a href="/wit/Open_Systems_Interconnection" title="Open Systems Interconnection" wx:linktype="known" wx:pagename="Open_Systems_Interconnection" wx:page_id="15022" id="wx53">modello OSI</a>. La sua funzione è quella di interfacciare e fornire servizi per i processi delle applicazioni; inoltra anche le richieste al <a href="/wit/Livello_di_presentazione" title="Livello di presentazione" wx:linktype="known" wx:pagename="Livello_di_presentazione" wx:page_id="296557" id="wx54">livello di presentazione</a>. Un programma applicativo interagisce con uno dei protocolli di livello trasporto per ricevere dati o inviarli passandoli nella forma richiesta.</p>

<p id="wx55">Tra i servizi più comuni offerti dal livello applicazioni ci sono le conversioni semantiche tra processi applicativi associati. <i id="wx56">Nota:</i> esempi di servizi usuali sono i <a href="/wit/File_virtuale" class="new" title="File virtuale" wx:linktype="unknown" wx:pagename="File_virtuale" id="wx57">file virtuali</a> ed il virtual terminal.</p>
