Telnet vs. FTP

The telnet and FTP (File Transfer Protocol) are the types of IP protocol. The main difference between the telnet and FTP is that the telnet allows a client user to login to the remote server to access its resources whereas that FTP is a file transfer protocol that does not provide a secure channel to transfer files.

FTP

Telnet provides a virtual terminal protocol that is standardized by ISO. In telnet first, a client-server connection is set and it links with a remote server. FTP is a file transfer protocol that is used to upload and download file between client and server. File from one host is copied and send to another host in FTP. The main purpose of telnet is to translate NVT from data and convert into accepted from and the main purpose of FTP is to transfer data from server to client.

What is Telnet?

Telnet allows a client user to login to the remote server to access its resources. Telnet provides a virtual terminal protocol that is standardized by ISO. In telnet first, a client-server connection is set and it links with a remote server. There is a remote machine that is identified by telnet that is client software. Because the different operating system runs on a different machine that is why it accepts a combination of unique characters as a token. Here comes Network Virtual Terminal (NVT) a universal interface defined by Telnet.

The telnet provides three services for its clients

  • Firstly, it provides an interface to the remote system defined by Network Virtual Terminal (NVT) as mentioned above.
  • Secondly, Telnet provides a mechanism which enables the client and the server to settle options and a set of standard options.
  • Lastly, both ends of the connection are equally treated by Telnet.

What is FTP?

The FTP (File Transfer Protocol) is basically used to transfer file from server to clients. FTP client establishes the connection with the help of the TCP. The FTP server allows multiple client to access the server concurrently. FTP sets up two connections between the hosts which makes it more efficient. The first connection is used for transferring the data and other for controlling the information (commands and responses). In the control connection, only one line of command or response is transferred at a time. In the whole FTP session, the control connection remains activated while data connection opens for transferring files and then closed when the file is completely transferred.

File Transfer Protocol have two types. Which are:

  • FTP
  • HTTP

FTP
FTP is a protocol that is used to sorts the problem when a communicating client and server have a different configuration. It is a file transfer protocol that is used to upload and download file between client and server. File from one host is copied and send to another host in FTP.

HTTP
HTTP provides a web page from the web server to web browser on request whereas FTP is used to upload and download file between client and server. The problems in HTTP is covered in FTP.

Key Differences between Telnet and FTP

  1. The telnet allows a client user to login to the remote server to access its resources. Whereas, The FTP is a file transfer protocol that does not provide a secure channel to transfer files.
  2. Telnet does not provide a security feature and it is unsecure. On the other hand, FTP is more secure than telnet.
  3. The Telnet protocol uses port number 23 for the connection. On the contrary, FTP uses port number 21 and 20 for connections respectively.
  4. In Telnet the user needs to log in first in the remote machine then any operations can be performed. Conversely, in FTP the user need not log in to the remote machine.
  5. The main purpose of telnet is to translate NVT from data and convert into accepted from. On the other hand, the main purpose of FTP is to transfer data from server to client.

Conclusion

The telnet and FTP both are IP protocols that is used to transfer the files. Both have some different specifications and are used in computer settings. Telnet is used for logging in the remote machine in order to access its resources while FTP is a file transfer protocol used to transfer a file from one host to another in a network or internet. Both have different port numbers also. The telnet and FTP both are very useful and the FTP also provide the security of your data.
