Highly depend on the protocol and the layer model.
Assuming it's ftp on ISO model.
The layer would be application, presentation, and the session layers.
FTP is the application layer protocol that is commonly used to support file transfers between a client and a server. Two forms of application layer software are applications and services.
data layer
File Transfer Protocol
FTP (File Transfer Protocol).
HTTP
You can use either TCP or UDP. If you need reliable connection use TCP otherwise UDP.
File Transfer Protocol (FTP), a standard Internet protocol, is the simplest way to exchange files between computers on the Internet. Like the Hypertext Transfer Protocol (HTTP), which transfers displayable Web pages and related files, and the Simple Mail Transfer Protocol (SMTP), which transfers e-mail, FTP is an application protocol that uses the Internet's TCP/IP protocols. FTP is commonly used to transfer Web page files from their creator to the computer that acts as their server for everyone on the Internet. It's also commonly used to download programs and other files to your computer from other servers.
Hypertext is the software language commonly used to write websites, Hyper-Text Transfer Protocol (HTTP) is the application protocol used to exchange hypertext between devices.
both are same...
In the context of smart cards, an application protocol data unit is the communication unit between a smart card reader and a smart card. The structure of the APDU is defined by ISO/IEC 7816-4 Organization, security and commands for interchange.
Border Gateway Protocol (BGP) is a way to transfer data and information between different hosts such the Internet or routers. It is commonly used between Internet Service Providers (ISPs).
Though this question is extremely ambiguous, you probably mean SNMP (Simple Network Management Protocol).
PPPoE (Point -to-Point Protocol Over Ethernet)
BGP is always used as the routing protocol of choice between ISPs (external BGP) but also as the core routing protocol within large ISP networks (internal BGP).
