Edge Computing

Definition

Edge computing refers to the practice of processing data closer to the source of data generation rather than relying solely on centralized data centers. This approach reduces latency, improves response times, and minimizes bandwidth usage, making it especially relevant in scenarios where real-time processing and immediate decision-making are critical. By enabling devices and applications to perform computations locally, edge computing enhances the efficiency and performance of interconnected systems.

Review Questions

• How does edge computing enhance the performance of IoT systems?
  • Edge computing enhances the performance of IoT systems by enabling data processing at or near the location where it is generated. This leads to reduced latency, allowing for quicker responses and decisions that are critical in applications like industrial automation and smart city management. By minimizing the need to transmit large amounts of data to centralized cloud servers, edge computing also helps improve bandwidth efficiency and overall system reliability.
• What role does edge computing play in mitigating security risks associated with data transmission?
  • Edge computing plays a significant role in mitigating security risks by processing data locally rather than sending it all to centralized cloud servers. By reducing the volume of sensitive information transmitted over networks, the attack surface is minimized, lowering the chances of data breaches. Additionally, local processing allows for better control over security measures and compliance with regulations, ensuring that sensitive data remains protected.
