The MAC address is also known as physical address or hardware address or Ethernet hardware address. The Manufacture of a network interface card assigns the MAC address and stores it in the hardware. So as the MAC is assigned by the manufacturer the MAC address encodes the manufacturer’s registered identification number. A network node having multiple NICs may only have one unique MAC address per NIC.

O    (Q) What are its specific tasks to ensure that the communication runs smoothly (no clashes, "ladies first"/gentlemen principle, etc.)?

The IP address is unique and any computer which accesses a public network should have this Unique IP address. This kind of host is called public host. In the case of public host the IP address is called public IP address. The schemes of IP addressing makes the host possible to “locate each other” online and to exchange the information.

The IP address in total is very limited in availability. So to assign unique IP address to all the computers in...
