The device that forwards data and operates at layer three of the Transmission Control Protocol/Internet Protocol (TCP/IP) model is a **router**.

### Explanation:
1. **Layer Three of the TCP/IP Model**: In the TCP/IP model, layer three corresponds to the Internet layer, which is responsible for routing packets of data from the source to the destination across network boundaries.

2. **Function of a Router**: A router operates at this layer by examining the destination IP address of incoming packets and determining the best path for these packets based on its routing table. It plays a crucial role in data forwarding between different networks, ensuring that data can traverse disparate network segments effectively.

3. **Routing Protocols**: Routers utilize various protocols (like RIP, OSPF, and BGP) to share information about network statuses and help figure out the optimal route for data transmission.

4. **Conclusion**: By making intelligent forwarding decisions and providing connectivity between multiple networks, routers facilitate efficient communication in complex network topologies.
