Activities
**********
Activities represent the actions that consume a resource, such as a
-:ref:`s4u::Comm <API_s4u_Comm>` that consumes the *transmitting power* of
-:ref:`s4u::Link <API_s4u_Link>` resources.
+:ref:`Comm <API_s4u_Comm>` that consumes the *transmitting power* of
+:ref:`Link <API_s4u_Link>` resources, or an :ref:`Exec <API_s4u_Exec>`
+that consumes the *computing power* of :ref:`Host <API_s4u_Host>` resources.
+See also the :ref:`full API <API_s4u_Activity>` below.
