What distinguishes logical segmentation from physical segmentation?

Logical segmentation is distinguished from physical segmentation primarily through the use of virtual configurations that create isolated segments within the same physical infrastructure. This approach allows network administrators to define and control traffic pathways, access rights, and security policies based on logical constructs rather than relying solely on the physical layout of devices.

For instance, virtual LANs (VLANs) are a common method of logical segmentation that can separate different types of traffic even when those segments share the same physical cables and switches. Logical segmentation facilitates greater flexibility and scalability, enabling changes to be made dynamically without requiring alterations to the physical hardware configuration.

In contrast, physical segmentation strictly relies on physical barriers and separate hardware components to isolate segments, which can be less efficient and harder to manage. Hence, logical segmentation's basis in virtual configurations is what sets it apart from physical segmentation.
