\frametitle{Les Types de données abstraits}
Pour communiquer entre eux, les processus doivent utiliser des objets partagés. \\
Pour spécifier la notion d'objets partagés nous allons d'abord cerner la notion de type de donnée abstrait :
\begin{block}{Définition}
Un type de donnée abstrait peut être défini par un automate tel que : $T = (A, B, Z, \zeta_0, \tau, \delta)$ \\
Tel que :
\begin{itemize}
\item A est un ensemble dénombrable (alphabet d'entrée)
\item B est un ensemble dénombrable (alphabet de sortie)
\item Z est un ensemble dénombrable d'états abstraits
\item $\zeta_0 \in Z$ est l'état initial
\item $\tau$ est la fonction de transition ($Z \times A \rightarrow Z$)
\item $\delta$ est la fonction de sortie ($Z \times A \rightarrow B$)
\end{itemize}
\end{block}

\begin{block}{Inconvénients}
\begin{itemize}
\item Introduit une notion de concurrence dans les tâches.
\item Il faut définir ce qu'on considère acceptable.
