c) A tool for connecting multiple networks
d) A hardware component
Answer:
a) A unique identifier for a device connected to a network
Explanation:
An IP address (Internet Protocol address) is a unique identifier assigned to each device connected to a computer network. It serves two main purposes: identifying the device and providing the location for data transmission over the network.
There are two versions of IP addresses: IPv4 (e.g., 192.168.1.1) and IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). The address allows communication between devices, directing data to the correct destination on a network or the internet.
IP addresses are essential for the functioning of the internet, as they ensure that data packets are routed correctly from the source device to the destination device, enabling seamless web browsing, email, and other online services.
