1, FTP (File Transfer Protocol) , file transfer protocol that is used to control the two-way transmission of files over the Internet.
(FTP in linux system, the transmission port is the default port 21, typically in ASCII and binary transfer mode data, supports active mode and the passive mode in two ways.)
2, SFTP (Secure File Transfer Protocol ), that is, file transfer protocol encryption.
(SFTP in linux system, the transmission default port is port 22, which is more secure transmission, transmission both sides password security verification, should be based on security authentication key, effectively prevent the "middleman" threats and attacks.)
3, the use of linux centos server system, the two comparison, ftp sftp transmission will be faster than the transfer rate, after all, sftp sacrifice some efficiency to ensure the secure transmission process.
4, summarized the difference:
