What does ARP stand for?

• A. Address Resolution Protocol (ARP)
• B. ARP
• C. Arpspoof
• D. Data Interception

Answer: (A)

ARP stands for Address Resolution Protocol. It’s the mechanism that translates an IPv4 address into the hardware MAC address needed to deliver frames on a local network. When a device wants to send to another host, it first checks its ARP cache; if the mapping isn’t known, it broadcasts an ARP request asking who has that IP, and the owner replies with its MAC address so the sender can update its cache and send the frame correctly. The other options don’t fit because they either don’t provide the correct expansion, refer to a tool, or describe something unrelated like data interception.
