Ethernet is a widely recognized standard for connecting devices in a local area network (LAN). It is a physical network interface that enables devices such as computers, routers, and switches to communicate with each other over wired connections. Ethernet utilizes specific cabling and protocols, making it a foundational technology for networking in various environments, from home networks to enterprise setups.

In contrast, the other options represent different concepts or methods of data management and distribution rather than physical network interfaces. File sharing relates to the process of transferring files between devices over a network, whereas disk encryption involves securing data on storage devices to prevent unauthorized access. Cloud storage refers to online services that allow users to store and manage data remotely over the internet. While all of these concepts are integral to data management and connectivity, only Ethernet serves as a physical interface that facilitates the actual transmission of data between networked devices.
