Which protocol is used to resolve IP addresses to MAC addresses?
Step 1: Understand that every device on a local network has two types of addresses: an IP address and a MAC address.
Step 2: Know that an IP address is used for identifying devices on a network, while a MAC address is a unique identifier for network interfaces.
Step 3: Realize that when a device wants to communicate with another device on the same local network, it needs to know the MAC address of the device it wants to reach.
Step 4: Learn that ARP (Address Resolution Protocol) is the protocol used to find out the MAC address that corresponds to a specific IP address.
Step 5: Understand that when a device sends an ARP request, it asks 'Who has this IP address? Please send me your MAC address.'
Step 6: Know that the device with the matching IP address responds with its MAC address, allowing the first device to communicate with it.
