Which standards define a protocol responsible for getting data to nodes on the same network or link?

The Ethernet standards are specifically designed to define protocols responsible for transferring data over a network link. These standards encompass various aspects of data communication, including frame formats, addressing, and how data packets are transmitted and received on a local area network (LAN). By establishing a set of rules for how devices connected to the same network communicate with one another, Ethernet standards enable efficient access to the network and facilitate proper data exchange among devices like computers, switches, and routers on the same physical medium.

In contrast, network standards cover a broader range of protocols and specifications used for networking, but they do not exclusively focus on the link layer functions that Ethernet standards provide. Application standards pertain to higher-level functions, dealing with how applications exchange data, while transport standards define how data is transmitted between hosts over a network, including error checking and data flow control. Together, these other standards are important for the overall operation of networks, but they do not specifically address the responsibilities of data delivery on the same link, which is where the Ethernet standards excel.
