Final answer:
IP addressing allows devices to identify and communicate with each other on a network.
Step-by-step explanation:
IP addressing is a fundamental concept in computer networking that is achieved through the use of Internet Protocol (IP) addresses. It allows devices connected to a network to uniquely identify and communicate with each other.
With IP addressing, data packets are sent to the correct destination by using the source and destination IP addresses. This enables routing and forwarding of information across different networks.
For example if you want to access a website, your device uses IP addressing to connect to the website server by sending data packets with the server's IP address as the destination.
