A LAN (Local Area Network) protocol refers to the set of rules and standards that govern communication within a local network, enabling devices to connect and communicate effectively. Common LAN protocols include Ethernet, which defines the physical and data link layers for wired connections, and Wi-Fi (IEEE 802.11), which enables wireless communication. These protocols ensure data packets are transmitted efficiently, manage access to the network, and provide error detection to maintain reliable communication among connected devices.
TCP/IP is the most common LAN protocol.
Your question is quiet confusing but if you are asking for the protocol for a computer inside the LAN to be able to communicate through the internet then it is the TCP/IP.
The older protocol for this purpose was BOOTP, but modern addressing LAN schemes today will use DHCP.

A spanning tree protocol, or STP, is characteristic to a LAN. It provides a loop-free topology for networks within the system.
A Local Area Network (LAN) is not directly connected to TCP (Transmission Control Protocol); rather, TCP is a protocol that operates at a higher layer in the networking stack. A LAN provides the physical and data link layers for connecting devices, while TCP functions at the transport layer to facilitate reliable communication between applications over a network. In a typical setup, devices on a LAN can use TCP to transmit data packets over the network, often in combination with IP (Internet Protocol).
