Answer: It's a model, not a protocol. The OSI model is a governing model of standards in which protocols are derived or fit into in the case of legacy models. The OSI model was developed by ISO(International Standards Organization). The OSI model encapsulates many popular legacy and current protocols including TCP/IP, IPX/SPX, and NetBIOs derivatives, including Microsoft's NetBEUI. The OSI model also includes specifications that allows communications engineers whos specialties are on different layers of the OSI model to communicate and accelerate delivery of better communications to the end user. So from DSL, modem, satellite to your web browser, the OSI model applies. e

Ethernet is a data link layer protocol - layer 2
FTP (File Transfer Protocol) is an application layer, or Layer 7, protocol.
Network Layer
TCP, the Transmission Control Protocol, is a layer-4 protocol (in the 7-layer OSI model).
Anything that is described in the OSI model is a standardized protocol, including any new ones such as IPv6.
UDP or User Datagram Protocol works on the Transport Layer (layer 4) in the OSI model.
