Detailed explanation-1: -FTP (File Transfer Protocol) is a network protocol for transmitting files between computers over Transmission Control Protocol/Internet Protocol (TCP/IP) connections. Within the TCP/IP suite, FTP is considered an application layer protocol.
Detailed explanation-2: -It transfers both text and binary files over the Internet. FTP opens two connections between the computers − one for the commands and replies (control connection) and a second one for data transfers (data connection).
Detailed explanation-3: -ASCII File: This is the default format for transforming a file from one to another. EBCDIC: If sender or receiver connections use the EBCDIC encoding method, then for transforming files, FTP uses EBCDIC encoding. Image File: For transforming the binary file, the image file is the default mode.
