Hey hylton,
The main advantage of having a VLAN is that they provide physical
independence while defining a logical entity. Say one of your account person sits
on first floor & in accounts vlan can be in the same subnet with the other
account person who sits at 10th floor.
However VLAN as a term, generally is considered to define a single
subnet but you can also define two or more subnets in a single VLAN.
In simplest words u can c a vlan as advanced stage of a subnet with many advanced options and facilities.
As per the security is concern, i cant see one more secure than another. both are eqally secure (or unsecure) however a vlan is much more flexible than a subnet.
Why and what(how) makes a VLAN more flexible? Using your example of a
single accounts person from the tenth floor sitting on the 1st floor,
all I would need to do for physical subnetting is make sure the 1st
floor accounts person' PC had the same subnet as those on the 10th floor.
In the end can I say that a VLAN is a LAN segment within a LAN exactly
as a subnet is a LAN segment inside a LAN ie a VLAN is a subnet?
