Final answer:
Each internet location has a unique IP address. It is a numerical label that identifies and locates devices on a network, much like a postal address for mail delivery.
Step-by-step explanation:
Each internet location has a unique IP address. The correct answer is c) IP. An Internet Protocol (IP) address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions; it identifies the host or network interface, and it provides the location of the host in the network, thereby making it possible to establish a path to that host.
An IP address is composed of numbers divided into sections and formatted as dotted decimals in IPv4 or as colon-separated hexadecimal blocks in IPv6. For example, an IPv4 address might look like 192.168.1.1, whereas an IPv6 address might appear as 2001:0db8:85a3:0000:0000:8a2e:0370:7334. Just like a postal address ensures that a letter reaches the correct destination, an IP address ensures that data is sent to the correct computer on a network.
