Fog computing is a method of processing and managing data closer to where it is created, such as sensors, devices, machines, and local networks. Instead of sending all information to a distant cloud server, some data is handled by nearby computing resources. This reduces the distance data needs to travel and can make applications respond more quickly.
It is useful for systems that need fast responses, continuous data processing, or reliable operation with limited internet connectivity. Common uses include smart cities, connected vehicles, industrial systems, security devices, and Internet of Things applications. Fog computing works alongside cloud computing, allowing local devices to handle time-sensitive tasks while larger or long-term data processing can still be performed in the cloud.
