Compare and contrast Fog Computing and Cloud Computing in IoT.
Answer
Fog computing processes data locally for low latency; Cloud handles massive global processing.
Fog computing operates at the edge of the network, closer to the IoT devices. It provides low-latency responses, reduces bandwidth consumption by filtering data, and can operate offline.
Cloud computing operates in centralized data centers. It handles long-term storage, complex Big Data analytics, and global accessibility. They are complementary: Fog handles the immediate, localized tasks, while the Cloud handles the overarching, long-term processing.
