Physical address is your mac address.. it'll be given by manufacturer... its fixed.. you can change it using some software.. but after you restart your system the original mac will be set...
to retrieve your MAC address(physical address) type
getmac in dos-mode
Logical address comes into picture when you talk about virtual memory...
i.e a part of the secondary memory is used as ram... there we refer logical address rather physical..
Hi Bashaece
DR( Designated Router) is elected when ever OSPF routers are connected to the same multi-access networks. It is done to reduce the number of adjancencies formed. If there is a change in topology the initial router will only updates the DR and BDR (Backup Designated Router). The DR in turn will update the remaining routers.
If the DR is down, then the BDR will act as DR.

HUB
1) hub works in the physical layer of osi model
2) hub broadcast the data
3) hub contain nothing any table
4) hub have not memory
5) hub contain one broadcast domain
6) hub contain one collision domain
7) hub contain one port are connect to next port with singal channel means on single channel all port transfer data to other port
