ARP (Address Resolution Protocol) is used to map a network address (such as an IP address) to a physical address (such as a MAC address).

• ARP is used in Ethernet networks to find the MAC address of a device based on its IP address.

• When a device needs to send data to another device on the network, it sends an ARP request asking for the MAC address of the destination device.

• The destination device responds with its MAC address, allowing the sending device to send the data directl...read more
