The definition of edge computing in data processing refers to the practice of processing data closer to the source, or "edge," rather than relying on a centralized data center. This approach reduces latency, improves response times, and decreases bandwidth usage, as data does not need to travel long distances for processing. Edge computing is particularly beneficial in applications requiring real-time analytics and decision-making, such as the Internet of Things (IoT), autonomous vehicles, and augmented reality. By leveraging local resources, organizations can enhance performance and user experiences.
