Every device on a TCP/IP network has a unique number assigned to it called the MAC address. The MAC address is used by the network hardware such as routers, switches etc. to send data from one device to another.
System uses a service called ARP (Address Resolution Protocol) to resolve and track the TCP/IP and MAC address of the remote devices that you are communicating.
