A device that filters data traffic at a network boun dery and reduce the amount of traffic on a LAN by dividing it into two segments?

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.
