Which of the following is the unique identifying number assigned to every device connected to the internet ?

  • A.BUS address
  • B.MAC address
  • C.IP address
  • D.BOOT address

Answer: C

The number is the IP address.

An Internet Protocol address is the numerical label assigned to each device connected to a network that uses the internet protocol, such as 192.168.1.10 in IPv4. It identifies the device and lets data be routed to it across the internet.

A MAC address is a hardware identifier of a network interface used within a local network, not for routing across the internet. 'BUS address' and 'BOOT address' are not identifiers of internet-connected devices.
