Ethernet is a data link layer protocol - layer 2
Ethernet switch fits on osi physical layer
because osi is open system interconnection that used to interact with open system
ports protocol

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).
The OSI (Open Systems Interconnect) 7-layer model is based, in-part, on standards published by the IEEE (Institute of Electrical and Electronics Engineers). For example, IEEE standard 802.3 describes Ethernet. In the OSI model, the 802.3 standard exists at layers 1 and 2. ANSWER IEEE is a standards organization to which many hardware and software suppliers both contribute to and agree to use 'standardized' techniques. Ethernet is but only ONE of the many standards, and the OSI is only one of the usage standards.
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.
Session, transport and network
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
