What tier focuses on communication and efficient data handling through various networking standards like PAN and LAN?

Device tier
Gateway tier
Cloud tier
Network tier

The correct answer is: Gateway tier

The gateway tier is responsible for connecting different networks and facilitating communication between them. It serves as an intermediary that translates and forwards data between disparate systems, enabling efficient data handling. This tier often involves routing traffic over various networking standards, such as Personal Area Networks (PAN) and Local Area Networks (LAN), to ensure seamless communication across different types of networks and devices. By managing the flow of information and handling protocol conversions, the gateway tier plays a crucial role in maintaining the integrity and efficiency of network communications. This tier is essential when devices on one network need to communicate with devices on another, particularly when those networks operate under different standards. The device tier focuses more on individual devices and their functionalities, while the cloud tier relates to services provided over the internet. The network tier deals more with the framework and pathways for data transmission rather than the direct handling through specific standards like PAN and LAN. Thus, the characteristics of the gateway tier align most closely with the question’s focus on communication and efficient data handling between various networking standards.
