Hi Sergiog, 
 
There are two types of nodes in Appian, 
Attended Node: Any node that requires a User Intervention is called attended node 
unattended Node.: Any node that doesnot require a user intervention is called un attended node. 
All the unattended node by default will have that option enabled i.e. This node will run as automated activity. It will not be assigned to anyone as task. 
For Attended nodes, The node must be assigned to a person or group. 
 
Script Task is an example of Un attended node and User input task is an example of attended node.
