For example, there are five computers (PC1~PC5) connected to
the Switch’s port 1~5. The 5 PCs are divided into two VLAN
groups, VLAN1 (PC1 ~ PC4) and VLAN2 (PC2 ~ PC5). In this
setup, PC1 could not communicate with PC5, because they are
not in the same VLAN group.

Using VLAN feature, you can group the computers on the Switch
into many independent small networks. For example, in Figure
16, the Switch has been divided into four VLAN groups. Each
VLAN group is independent and there is no communication
between the VLAN groups.
