What serves as the main site controller for Radiant stores?

The main site controller for Radiant stores is the HP EliteDesk. This device is designed to function as a robust platform that supports various operational tasks at the store level, including running applications essential for point-of-sale systems and maintaining connectivity within the retail environment.

The EliteDesk is equipped with the necessary processing power and storage capabilities to handle transactions, manage inventory, and support the overall system architecture, making it a central component in the operational setup of Radiant stores. Its reliability and performance as a desktop computer tailored for business use provide a solid foundation for store management.

In contrast, other options like PAM-5000, Front Counter Switch, and Network Router serve specific functions within the network and operational structure but do not serve as the main site controller. The PAM-5000 acts more as a network appliance used for different purposes, the Front Counter Switch is involved in communication tasks, and the Network Router facilitates network traffic. However, none of these serve the central role that the HP EliteDesk does in managing overall store functions and operations.
