Edge Computing

A network architecture in which a substantial amount of computing, communication, and storage takes place at the network edge. Similar to fog computing, edge computing involves pushing processing capabilities and intelligence closer to where data originates, with the goal of reducing the volume of data being sent to the cloud, decreasing network/Internet latency, and improving system response time. But whereas those processing and other functions are pushed down directly to devices such as programmable automation controllers, or PACs, in edge computing, they’re pushed to the LAN level in fog computing.
