Q: Which gadget uses the Transmission Control Protocol/Internet Protocol (TCP/IP) model’s third layer to forward data?
- Client
- Switch
- Router
- Hub
Explanation: A router is a device that works at Layer 3 of the TCP/IP architecture and is responsible for the forwarding of data. Routers are devices in networks that function at the Network layer and are in charge of directing data traffic across various networks based on logical addressing (such as IP addresses). Routers are classified as operating at the Network layer. They are responsible for determining how data packets should be sent from one network to another across linked networks to facilitate communication between devices that are located on separate subnets or networks.
