Correct Answer :
Identify a computer on a network
An IP address (Internet Protocol address) is a unique numerical identifier assigned to every device connected to a network. Its primary purpose is to allow devices to identify and communicate with each other over the internet or local networks. It ensures proper routing of data between the sender and the recipient. Examples include IPv4 (e.g., 192.168.1.1) and IPv6 addresses.
