Edge devices

Definition

Edge devices are computing hardware that exist at the edge of a network, acting as an intermediary between data sources and cloud-based servers. These devices process data locally to reduce latency, optimize bandwidth usage, and enhance the speed of data transmission in environments that require real-time processing. They are increasingly significant in the context of advanced networking technologies, such as 5G, as they enable faster responses and more efficient data management.
