Which device would be used to connect different network segments while managing IP traffic?

A router is used to connect different network segments while managing IP traffic. It performs the essential function of forwarding data packets between different networks based on their IP addresses. When a data packet is sent from a device in one network to a device in another network, the router determines the best path for that packet to reach its destination, ensuring efficient and accurate data transmission.

In addition to connecting disparate networks, routers also provide functionalities such as network address translation (NAT), firewall protection, and DHCP services, which are critical for maintaining network security and organization. They enable devices on different IP address spaces to communicate with each other, making them a vital component in modern networking.

Other devices mentioned do not serve the same purpose. For instance, switches primarily operate within a single network segment and manage data traffic at the data link layer by using MAC addresses for forwarding decisions. Hubs, on the other hand, are basic devices that do not manage traffic and simply broadcast incoming data packets to all connected devices, which can lead to collisions and inefficiencies. Repeaters are used to extend the range of a network by amplifying signals but do not involve any traffic management or routing between network segments.

Thus, a router is specifically the device designed for inter-network communication and management
