c) To encrypt data
d) To provide power to network devices
Answer:
a) To uniquely identify a device on a network
Explanation:
An IP (Internet Protocol) address is a unique identifier assigned to each device connected to a network. It allows devices to communicate with each other by routing data between them through the internet or local networks.
There are two versions of IP addresses: IPv4, which uses a 32-bit address format (e.g., 192.168.1.1), and IPv6, which uses a 128-bit format (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334) to accommodate more devices.
IP addresses are critical for network communication, as they ensure that data is sent to the correct device in a network, making online services, email, and web browsing possible.
