What is the term used to describe segmenting traffic between different portions of a single LAN?

The term used to describe segmenting traffic between different portions of a single LAN is traffic isolation. This process involves creating separate virtual networks or segments within the same physical network to ensure that traffic is contained within specific segments. By doing so, it enhances security, improves performance, and helps in managing bandwidth more effectively across the network.

Traffic isolation reduces the chances of broadcast storms affecting the entire network and limits the potential impact of a security breach in one segment on the entire LAN. Overall, it allows for better organization and control of network resources, making it a crucial practice in network design and administration.
