The main characteristic of edge computing is its ability to process data closer to the source where it is generated, rather than relying on a centralized data center. This decentralized approach reduces latency and bandwidth usage, enabling faster data processing and real-time analytics. Edge computing is particularly beneficial for applications requiring immediate responses, such as in IoT devices, autonomous vehicles, and smart manufacturing. By minimizing data travel distances, edge computing enhances performance and responsiveness, ultimately leading to improved user experiences and operational efficiency.
