Which statement correctly defines an IP address?

• A. A numeric label assigned to devices on a network to identify them.
• B. A unique hardware address known as a MAC address.
• C. The memory address where programs are loaded.
• D. A domain name used to access websites.

Answer: (B)

An IP address is the numeric label assigned to devices on a network to identify them and to allow data to be routed from one device to another. It identifies a device’s location in a network so routers know where to send packets. There are two versions: IPv4, which uses four decimal numbers separated by dots (like 192.168.1.5), and IPv6, which uses eight groups of hexadecimal numbers separated by colons. IP addresses can be public (routable on the internet) or private (used inside local networks) and can be assigned permanently or dynamically by protocols like DHCP. This is different from a MAC address, which is a hardware identifier built into a network interface card and used only on the local link, not for routing across networks. It also differs from a domain name, which is a human-friendly label that DNS translates into an IP address. A memory address, on the other hand, points to where software resides in RAM and is unrelated to network identification.
