Review Questions
How does real-time decision making enhance operational efficiency in IoT systems?
Real-time decision making enhances operational efficiency in IoT systems by allowing immediate analysis and response to incoming data from devices. For instance, if a sensor detects an anomaly in equipment performance, real-time decision making enables automated systems to initiate corrective actions swiftly, minimizing downtime and preventing further issues. This immediacy ensures that operations remain smooth and efficient.
Discuss the role of latency in real-time decision making and how edge and fog computing help mitigate its effects.
Latency plays a critical role in real-time decision making because any delays can lead to ineffective responses or missed opportunities. Edge computing addresses this by processing data closer to its source, significantly reducing the time it takes for information to travel to a central server. Fog computing further aids this by distributing processing tasks across multiple nodes in the network, which helps ensure that decisions are made as quickly as possible, keeping latency low.
Evaluate the impact of real-time decision making on industries such as healthcare and transportation in relation to edge and fog computing.
Real-time decision making has a profound impact on industries like healthcare and transportation, especially when supported by edge and fog computing.
