Later, instead of NCP, TCP / IP ie Modern Internet was used. As changes occurred on the Internet, FTP was also updated.

There was a time when there were problems in the FTP connection of the firewall installed in the computer, to deal with which FTP was made firewall friendly, for which passive mode was added.

How does FTP work?

Now let’s understand how the FTP protocol works. For this, first FTP client should be installed in the user’s system, apart from this you should have username and password to establish connection to the server.

FTP uses two types of connections to transfer files:

  1. Control Connection: This is used to open or close a connection and send commands to the server.
  2. Data Connection : File transfer is done between client-server through data connection after the connection is established.

The control connection is initiated by the client on port number 21, when the connection is established, commands are sent by the client and according to the command the server starts the data connection on port number 20 and files are transferred through this data connection.

FTP can work in two different modes:

  1. Active Mode:
  2. Passive Mode:

Active Mode:

  • In active mode the client connects to port 21 of the FTP server using any port number (greater than 1023) i.e. opens the control connection.
  • After this The client tells its port number to the server on which to establish a data connection.
  • After getting the port number of the client, the server opens the data connection from its port 20 to the port number of the client.

Passive Mode:

  • In Passive mode the client opens a command connection from any port number (greater than 1023) to the port 21 of the FTP server.
  • FTP client through that command connection to the server Sends the PASV command.
  • FTP server communicates its port number to the FTP client with the same command connection.
  • The port number of the client and the port number specified by the server on behalf of the FTP client The data connection is opened between

What is the difference between FTP and HTTP?

  • Two-way communication can be done by FTP i.e. we can copy or move any file from server to client system and upload any file from client’s computer to server.
  • HTTP Works on a one-way communication system that displays text, images, videos, etc. from the server to the client’s browser.
  • Through FTP the user can view the directory structure of the server while HTTP It can be hidden in this.
  • what is ftp : FTP  is better for large files transfer while it is better to use HTTP to transfer small data.
  • In FTP A file can be transferred from the server and saved automatically on the client’s computer, but in HTTP, the user has to save the content displayed on his/her browser.

what is ftp : The full form of FTPS is “File Transfer Protocol – Secure” or “File Transfer Protocol – SSL”.

As we mentioned, FTP is a very old protocol which has been running since 1971 and data encryption was not used at that time, so it is obvious that data is not secure in FTP and this is its biggest weakness.

To overcome this weakness of FTP, FTPS i.e. File Transfer Protocol Secured was created which works like FTP but all the data is encrypted in it which cannot be easily read by hacking. Nowadays, mostly FTPS is used.

what is SFTP?

The full name of SFTP is “SSH File Transfer Protocol”. The difference between FTPS and SFTP is that SSH ie Secure Shell is used for a secure connection in SFTP while FTP protocol is used in FTPS.

SFTP is a kind of binary protocol in which all the commands are converted into binary and sent to the server in the form of packets so that the file transfer becomes even more secure and fast.

In FTP, user id, password and certificate are used for authentication, while in SFTP connection, apart from user id, password, SSH keys can also be used for authentication.
