Explain VLAN segmentation as you would to a capable student, in 3-4 sentences.

# VLAN Segmentation A VLAN (Virtual Local Area Network) lets you divide a single physical network switch into multiple isolated logical networks, as if you had separate switches for different groups. For example, you could segment your company network so that HR, Engineering, and Guest WiFi all share the same physical equipment but can't see each other's traffic. This improves both security (by isolating sensitive data) and performance (by reducing broadcast traffic to only relevant devices). Think of it like creating separate, soundproof rooms within one building—everyone shares the same infrastructure, but each group operates in their own protected space.
