TCP/IP (Enable/Disable TCP/IP)
The TCP/IP system refers to the Internet system, which has a 5-layer structure consisting of the interface layer, link layer,
network (IP) layer, transport (TCP/UDP) layer and application layer.
The interface layer is a key layer in the TCP/IP system that provides an abstracted interface that is not dependent on the
link (communication line: frame relay or Ethernet, etc.) to the IP module (IP layer). This means that the IP module can use
this abstracted interface (which is not dependent on the link type) to exchange IP packets back and forth with the link layer.

DHCP (DHCP setting)
DHCP (Dynamic Host Configuration Protocol) is the protocol that assigns the information required to establish a network
connection when a host attempts to connect to the network (Internet). This information includes the IP address of the local
node and the default router (the router in the host's own network system) and the DNS (Domain Name System) server.
DHCP is an extension of the BOOTP (Bootstrap) startup protocol.
