E-mail and FTP, like all client applications, operate at the Application Layer.
FTP operates in application layer of ISO OSI layered model.
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.
FTP, NFS, DNS, email, and HTTP (the web browsing protocol) all rely on client server model.
HTTP Belongs to the Application layer. Other transfer protocols like POP,FTP,SMTP etc also belongs to this layer
Application Layer 7
FTP operates in application layer of ISO OSI layered model.
FTP (File Transfer Protocol) is an application layer, or Layer 7, protocol.
ftp i.e file transfer protocol,used to transfer a file from node to node FTP works at OSI layer 7, the Application layer
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.
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.
FTP and Telnet are considered OSI layer 7 protocols. If you are blocking the service, then layer 3 or 4 (network or transport) is responsible.
Telnet is an application layer protocol (Layer 7). Its functionality is similar to any of the layer 7 protocols, including DHCP, DNS, FTP, etc.
DNS is an application layer protocol. The application layer of the OSI model is the layer closest to the user and provides network services to the applications of the user. Examples of protocols that operate at the application layer are: DNS, FTP, TFTP, SNMP, TELNET, RLOGIN, SMTP, MIME, NFS, FINGER, BOOTP and SMB.
There are more than 3 protocols at the application layer. Three well-known protocols are: HTTP - web page traffic FTP - file transfer traffic SMTP - email transfer
