Concept explainers

VLAN

VLAN stands for Virtual Local Area Network, and it is created from one or more local area networks. A Virtual Local Area Network (VLAN) is a customized network made up of one or more LANs. It allows a set of devices from different networks to be converted into a single logical network. As a result, a virtual LAN that is managed similarly to a physical LAN emerges.
