From John Rayworth's excellent site (here):
Centrally controlled system - A hardware and/or software IT system in which all parts of it are controlled by a central controller/server/mainframe[2].
(Purely) Distributed system - A hardware and/or software IT system in which various parts of the control and/or processing are controlled by individual controllers/servers/computers throughout the system[3].
An important distinction[edit]
Please remember, for the rest of your life, the image below, and the distinction between centralized, decentralized, and distributed networks.
