Exploring Fog and Edge Computing

What is fog computing and how does it differ from cloud computing?

• Fog computing is a decentralized computing infrastructure that processes data closer to the source, while cloud computing centralizes resources in remote data centers.

• Cloud computing is a decentralized network that operates locally.

• Fog computing is a type of cloud computing that relies on centralized servers.

• Fog computing only stores data without processing it.

Explain the concept of edge computing in relation to fog computing.

• Fog computing eliminates the need for edge devices entirely.

• Edge computing processes data at the source, while fog computing extends this by adding intermediate nodes for distributed processing.

• Edge computing is only used in cloud environments.

• Edge computing and fog computing are the same concept without any differences.

Describe the hierarchy of fog and edge computing.

• Edge Devices, Cloud, and Data Centers

• Fog Nodes, Cloud Services, and IoT Devices

• The hierarchy of fog and edge computing consists of Edge Devices, Fog Nodes, and Cloud.

• Traditional data center management

• Primary use cases for fog computing include smart cities, healthcare, manufacturing, and agriculture.

Explain the significance of latency in fog and edge computing.

• Latency is irrelevant in fog and edge computing.

• Latency is significant in fog and edge computing because it reduces response times and enhances the performance of real-time applications.

• Higher latency improves the performance of applications.

• Latency only affects data storage, not processing.
