Which of the following describes the 'Application Process Security' layer in IIoT?
Application Process Security protects the higher-level industrial execution logic and workflow rules beyond basic network packet filtering and encryption.
Which semantic web format recommended by W3C is widely used to represent WoT ontologies and domain relationships?
RDF and OWL provide formal semantic representations that enable WoT applications to reason autonomously about device types, spatial locations, and measurement units.
In IoT software agent resource management, what is 'Synchronization' among distributed agents?
Agent synchronization uses distributed consensus protocols to ensure autonomous agents agree on global system state and resource allocation across factory production lines.
Which component in an IIoT architecture directly interfaces with physical sensors/actuators to execute hard real-time control loops (e.g., 1-millisecond response cycles)?
PLCs and PACs operate at the deterministic field execution level, running hard real-time control loops that cannot rely on network-delayed cloud connections.
What is 'Dependability' in critical IoT and IIoT system engineering defined as?
Dependability is an umbrella measure of system quality containing five core attributes: Availability, Reliability, Safety, Confidentiality/Integrity, and Maintainability.
