Edge Computing

Edge computing is a distributed computing paradigm that brings computation and data storage closer to the sources of data, rather than relying on a centralized cloud. By processing data locally on or near the "edge" of the network—using devices like IoT sensors, smartphones, or local servers—this model significantly reduces latency and bandwidth consumption. This approach is critical for applications requiring real-time responses, such as autonomous vehicles, augmented reality, and industrial automation, as it enables faster data processing and decision-making without the delay of sending data to a distant cloud server.
