Editing Introduction to Edge Computing (section)

===1.4.1 Fog Computing ===
Fog computing is an architecture introduced by Cisco to extend cloud services to the edge of the network. Instead of sending data from edge devices directly to the cloud, fog computing enables processing, storage, and analysis to occur closer to the data source, such as on local routers, gateways, or switches. This paradigm creates a layered system where intermediate nodes handle computations, reducing latency and bandwidth usage. It supports a decentralized model, which is ideal for real-time applications like industrial automation, smart traffic lights, and autonomous systems. Fog computing enhances scalability and responsiveness while maintaining a link to the central cloud for more intensive processing or long-term storage.
