Question
What protocol is used to find the hardware address of a local device?
- RAR
- PAR
- PIC
- ICMP
- IP
Solution
The protocol used to find the hardware address of a local device is ARP (Address Resolution Protocol). ARP is a communication protocol used on local networks to map IP addresses (logical addresses) to MAC addresses (physical hardware addresses). When a device wants to communicate with another device locally, it uses ARP to discover the MAC address corresponding to the IP address it wants to reach.
When a device sends an ARP request, it broadcasts this request to all devices on the local network. The device that recognizes the IP address responds with its MAC address, allowing the sender to establish a link-layer communication with the addressable device.
In summary, the answer is ARP.
