What kind of resolution is Address Resolution Protocol (ARP) used to perform?
Address Resolution Protocol (ARP) is used to perform IP to MAC resolution, translating IP addresses to physical MAC addresses on a local network. Thus, the correct option is C.
What is Address Resolution Protocol (ARP)?
Address Resolution Protocol (ARP) is a protocol used to map an IP address to a physical machine address. In simpler terms, ARP is used to resolve IP addresses to MAC addresses on a local network.
How does ARP work?
ARP works by broadcasting a request packet onto the network to discover the MAC address of a device with a known IP address. The device with the corresponding IP address then responds with its MAC address, allowing the sender to communicate directly with the recipient on the network.
Why is ARP important?
ARP is crucial for communication between devices on a local network. Without ARP, devices would not be able to accurately determine the MAC addresses of other devices, hindering the delivery of data packets on the network.
Example of ARP in action
Suppose a computer wants to send data to another device on the same network. The sending computer would use ARP to determine the MAC address of the receiving device using its known IP address. Once the MAC address is resolved, the data packets can be successfully delivered to the intended recipient.
Conclusion
In conclusion, Address Resolution Protocol (ARP) plays a vital role in network communication by translating IP addresses to MAC addresses on a local network. By understanding how ARP works, network administrators can troubleshoot connectivity issues and ensure smooth data transmission between devices.
