The mode of operation of the FTP protocol is based on two basic processes of controlling connections and data connections.This happens between an FTP client and an FTP server, also known as Control Connection and Data Connection.

Control connection:When the session starts, during the process of the job, this process will control the connection and only perform the task of control information passing through the process. data transmission.
Data connection (data connection):Unlike the Control connection, this is a process to make connections but no longer control.It will connect the data whendata is sent from the server to the client or vice versa.This process goes through the process until the data transfer is completed and it also stops.

Methods of data transmission in the FTP protocol

As we mentioned above, FTPis a protocol for transferring files from one computer to another computer via a TCP network or over the Internet.And this transmission is done in 3 different modes: Stream mode, Block mode, and Compressed mode.Specific methods are as follows:

Stream mode: A file transfer method without aheaderstructure.Based on the reliability of the data transmission and through TCP connection to the receiving side, only the disconnection is the data will end.
Block mode: The data transmitted is divided into small segments and then repackaged into FTP blocks, each packet contains data information and this will be a safer, more standard data transmission.
Compressed mode:The thirdmethod implemented by the FTP protocol, this method will help files and data transfer if encountered too severe cases, they will help handle that file segment by compressing them and simple transfer.However, currently the transmitted files are compressed appropriately soBlock mode will not be needed.
