La couche présentation utilise les services de la couche session, et offre ses services à la couche application par une traduction des informations en un langage commun.
Elle s'assure de la compatibilité en vérifiant que l'information envoyée par la couche application d'un système sera lisible par la couche application d'un autre système.
Nous pouvons trouver à ce niveau une gestion de cryptage ( sécurité ) et de compression.

All you need to do is register on the site, and send me a message asking me to add you to the group of translators, which will give you the opportunity to translate the pages you want.
