Edge computing and fog computing allow processing data within a local network rather than sending it to the cloud, which decreases latency and increases security. The main difference between the two is processing location. With edge computing, data processing typically occurs directly on a sensor-equipped product that collects the information or a gateway device physically close to those sensors. Fog computing moves edge computing activities to local area network (LAN) hardware or processors connected to it. These may be physically farther from the data-capturing sensors compared to edge computing.
