Which statement is incorrect about fog computing?

Fog computing is designed to bring computing resources closer to the data source, which can help in generating big data and reducing latency. This architecture allows for processing to occur at the edge of the network rather than relying solely on centralized cloud servers. This proximity enhances the speed of data processing and real-time decision-making, which aligns with why generating big data and reducing latency is one of its strengths.

Additionally, fog computing effectively buffers data and reduces network pressure by distributing workloads across multiple nodes rather than funneling everything through a central cloud. This distribution minimizes bandwidth consumption and alleviates the strain on the network.

While fog computing does offer benefits in terms of localized data processing and management, the claim regarding security is more nuanced. Fog computing does not necessarily provide better security than cloud computing; rather, it offers different security strategies due to its distributed nature. The level of security is contingent upon how both fog and cloud systems are designed and implemented. Thus, the assertion that fog computing inherently offers more reliable security than traditional cloud computing is misleading, making it the incorrect statement among the options provided.

Moreover, limiting data movement to local networks is a fundamental characteristic of fog computing, as it keeps data processing closer to where data is generated, facilitating greater efficiency and lower latency without excessive
