Edge computing

Definition

Edge computing is a decentralized computing model that brings computation and data storage closer to the location where it is needed, rather than relying solely on a central data center. This approach reduces latency, enhances speed, and improves efficiency by processing data closer to the source, which is especially vital in environments with a large number of connected devices and high data generation.
