Final answer:
A VLAN is the method used for separating a network into smaller private networks, allowing them to coexist on the same wiring while being unaware of each other, thus creating protected areas within a network.
Step-by-step explanation:
The popular method for breaking a network into smaller private networks is VLAN, which stands for Virtual Local Area Network. VLANs allow for the creation of multiple, segmented networks that can exist on the same physical network infrastructure but operate as if they are completely separate.
This technology helps to set up many, small, protected areas within a network, thereby enhancing security and reducing traffic. Those within a VLAN can communicate as though they were on their own isolated network, even if there are multiple VLANs on the same switch or across multiple switches.
The popular method for breaking a network into smaller private networks that can coexist on the same wiring and yet be unaware of each other is VLAN (Virtual Local Area Network). VLANs allow a network administrator to logically divide a physical network into multiple broadcast domains. Each VLAN acts as a separate network, enabling them to coexist and operate independently of one another.
