VLANs (Virtual Local Area Networks)

VLANs (Virtual Local Area Networks) are a way to segment a physical network into multiple, separate digital networks within the same hardware. Imagine a large office with different departments; VLANs allow each department to have its own private network, even though they all use the same physical switches and cables. This improves security, reduces broadcast traffic, and simplifies management by isolating groups of devices logically, independent of their physical location. Essentially, VLANs create customized, secure digital communities within a shared network infrastructure.
