Re: Different terms for the same or more secure?

NO ONE has answered the simple initial question of what is a VLAN?
David, THANK YOU I hope you have investigated technical lecturing/teaching.

In essence it is a group of ports (ie 4 ports of a total of 32) that have their own MAC table. Connecting those ports to a similar configured switch would create a LAN in a LAN or VLAN.

Would the IP addressing be different between for the clients on the VLAN as opposed to the normal nodes clients? I would assume not, however I cannot figure out why VLANs are needed with IP subnetting? ie what is the benefit of a VLAN over a subnet?

Would the nodes on the VLAN be more secure or have the same security as the normal nodes?

<snip> Davids EXCELLENT reply

PS: If you don't mind I think we should make this topic private as apart from the initial security question, I can feel the MODERATOR breathing down my neck :)
