In result i can find many entries with name Physical Address. Which one actually represent my machine mac address? My understanding is MAC address is unique for a computer whether we are connected on LAN/WLAN or not connected at all?

回答1:

A MAC address is not unique for a computer, it is unique for a Network Interface Card.
getmac /V gives you a more compact list of your interfaces.

EDIT:
Don't take "Card" literally as it may not be a whole separate Card connected to your motherboard. Most NICs nowadays are just integrated on-board.
