The device you’re referring to is typically a router or a switch with VLAN (Virtual Local Area Network) capabilities. By segmenting the network into two or more parts, it reduces broadcast traffic and improves overall network performance. This segmentation helps isolate network issues and enhances security by controlling traffic flow between segments. Additionally, it allows for better management of network resources and can improve bandwidth utilization.
This device is called a ROUTER. Routers are by default configured to not pass the broadcast traffic to another networks to which it connects. But by some means it could be also a SWITCH - sometimes it can be configured to filter different type of network traffic.
