Review Questions

• How does IoT enhance operational efficiency in various industries?
  • IoT enhances operational efficiency by enabling real-time monitoring of systems and processes. For instance, sensors can track equipment performance or environmental conditions, allowing companies to identify issues before they become major problems. This proactive approach reduces downtime and improves resource allocation, ultimately leading to cost savings and increased productivity.
• Discuss the security challenges associated with IoT implementation and how they can be addressed.
  • Security challenges in IoT arise from the interconnectedness of devices, which can expose vulnerabilities that hackers may exploit. To address these challenges, organizations should implement strong encryption protocols for data transmission and establish regular software updates to patch security gaps. Additionally, employing network segmentation can limit the impact of potential breaches by isolating IoT devices from critical networks.
• Evaluate the impact of edge analytics on the functionality and performance of IoT systems.
  • Edge analytics significantly enhances IoT systems by processing data near its source rather than sending it all to a centralized server. This reduces latency, enabling quicker decision-making based on real-time insights. By minimizing bandwidth use and improving response times, edge analytics ensures that IoT applications are more efficient and effective, particularly in environments where immediate action is crucial.
