In this note we describe the theory of functional asynchronous networks and one of the main results,
the Modularization of Dynamics Theorem, which for a large class of functional asynchronous networks gives
a factorization of dynamics in terms of constituent subnetworks. For these networks we can give a complete
description of the network function in terms of the function of the events comprising the network and thereby
answer a question originally raised by Alon in the context of biological networks.
