FTP operates in application layer of ISO OSI layered model.
E-mail and FTP, like all client applications, operate at the Application Layer.
FTP (File Transfer Protocol) is an application layer, or Layer 7, protocol.
File Transfer Protocol (FTP) is found in the TCP/IP stack of the Application Layer of the OSI reference model. FTP is specialized for sending and receiving files.
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
HTTP Belongs to the Application layer. Other transfer protocols like POP,FTP,SMTP etc also belongs to this layer
E-mail and FTP, like all client applications, operate at the Application Layer.
FTP (File Transfer Protocol) is an application layer, or Layer 7, protocol.
There are many more than three protocols which can operate at the application layer. Some of these are; Telnet FTP TFTP SMTP IMAP POP DNS RARP BOOTP SNMP CMOT
ftp i.e file transfer protocol,used to transfer a file from node to node FTP works at OSI layer 7, the Application layer
smtp(simple mail transfer protocol,),ftp,(file trasfer protocol),ip(nternet protocol).
Routers operate at layer 3. LAN switches operate at layer 2. Ethernet hubs operate at layer 1.
since it is a server it would be at your phyiscal layer, or if you are taling about the FTP service then that will be at the applaction level.
Layer 7, Aplication
Bridge operate on data link layer
Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.
Application Layer 7
File Transfer Protocol (FTP) is found in the TCP/IP stack of the Application Layer of the OSI reference model. FTP is specialized for sending and receiving files.
