Interface UDP
Le protocole UDP (User Datagram Protocol) est un protocole de transport superposé au protocole Internet (IP). Utilisez l'interface UDP pour lire et écrire des données binaires et des données ASCII. Vous pouvez lire et écrire sur des serveurs, des ordinateurs, des instruments et utiliser des applications telles que le streaming vidéo et audio, les systèmes de point de vente et d'autres applications professionnelles.
