Ethernet is a communication protocol for Local Area Network (LAN) using the same media interfaces (mainly RJ45 or fiber).
LAN are independent networks but may be linked within a WAN through Internet devices such as cable, Routers.

Ethernet is a standard for connecting many types of network device.
LAN is "Local area network", the part of the internet system that is "inside" your router's firewall and noramly using private IP addresses issued by the router.
The connection from the router to the internet and through your internet providers equipment is WAN - Wide area network, the internet that uses public IP addresses etc.
Ethernet is a commonly used network connection system, but it's not the only one by any means.
There are such as fibre optic systems, "Infiniband", equipment that has SFP sockets for a plug-in choice of interface types, token ring and others.
Those are mostly faster than common ethernet types, but also more expensive and generally the interface cards need a lot more power than an ethernet port as well.
