ARP is a protocol belonging to Layer 3 network layer in OSI Layer and is used to know the MAC address of another PC or server for communication. And the MAC address translation operation for the destination ip address. It is transmitted in the form attached after the Ethernet header, and the data transmission method uses broadcast.ARP is used to know the MAC address, and RARP is used to know the..

The LAN consists of the synchronization signal, the MAC address (destination) of the other party, the MAC address (source) of the sender, the packet type (next protocol), and the IP header and TCP header according to the protocol type.LAN은 통신의 시작을 알리 동기신호와 상대방의 MAC 주소(목적지), 송신자의 MAC 주소(발신지), 패킷유형(다음에 올 프로토콜) 그리고 프로토콜 종류에 따라 IP헤더, TCP헤더로 구성로 구성된다.
