For example, there are five computers (PC1~PC5) connected to
the Switch’s port 1~5. They had been divided into two VLAN
groups: VLAN1 (PC1~PC4) and VLAN2 (PC2~PC5). There is
no way to connect PC1 and PC5, as shown in Figure 15. If PC1
has to connect to PC5, it should with it in the same VLAN.

Using VLAN, the Switch can be divided into many independent
small switches. For example, in Figure 16, the Switch has been
divided into two VLAN groups. Both VLAN groups are
independent and there’s no link between these VLAN groups.
The Switch can be regarded as two smaller switches.
