They allow administrators to segment a network into smaller, isolated sections without requiring additional physical infrastructure. This logical partitioning increases efficiency, improves security, and simplifies management. In traditional local area networks, devices that are physically connected to the same switch are considered part of the same broadcast domain. With VLANs, however, this boundary is no longer dictated by physical topology. Instead, devices can be grouped logically based on function, department, or application, regardless of their physical location. The...
