RE: Different terms for the same or more secure?

[Anhtuan Huynh <anhtuan.huynh () inttra com>]

no true. you can only have one subnet per vlan, however, private vlan can be
used to further isolate the 
vlans. also if your using a switch with l3 capability, intervlan routing can
be used (SVI). 

192.168.1.0/24 = VLAN 10
192.168.2.0/24 = VLAN 11

you can't have 192.168.1.0 and 192.168.2.0 on VLAN 10. VLAN is a L2 not L3,
therefore seperating the
broadcast domain independantly.

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.
