Difference Between Telnet and FTP

Main Difference

The difference between telnet and FTP is that telnet allows a client user to login to the remote server to access its resources whereas FTP is a file transfer protocol that does not provide a secure channel to transfer files.

Telnet vs. FTP

A connection to the server from the remote host to remotely log in to a system to transfer file is IP protocol that is also known as application layer or connection-oriented layer. Telnet and FTP are types of IP protocol. If we talk about the main difference, then the main difference between telnet and FTP is that telnet allows a client user to login to the remote server to access its resources whereas FTP is a file transfer protocol that does not provide a secure channel to transfer files. There are many file transfer protocol, the use to file transfer protocol is to transfer data from client to server. There are two types of file transfer protocol that are HTTP and FTP. HTTP perform the combine function of both FTP and SMTP. If we talk about the main difference, then the main difference between HTTP and FTP is that 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. FTP is a protocol that is used to sorts the problem when a communicating client and server have a different configuration. 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. There can be a problem that can occur in FTP while transferring data from one host to another. There is a communicating host that can have different file name conventions and can also have different directory structures. HTTP can have different ways to represent data. The problems that are in HTTP are cover in FTP. When two hosts from different configuration want to exchange data FTP is used in place of HTTP. Telnet allows a client user to login to a remote server to access its resources. Telnet provide 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 different operating system runs on a different machine that is why it accepts a combination of unique characters as a token. NVT is a network virtual terminal that is a universal interface that is defined by telnet. The main purpose of telnet is to translate NVT from data and convert into accepted from. TCP services are used in FTP that can exchange any data. Two connections are used in FTP that is data transfer on TCP’s port number 20 and one separate connection of data. Control connection that is not used in HTTP is used in FTP. The security system is very high in FTP as compared to HTTP.

What is Telnet?

What is FTP?

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.

Control connection that is not used in HTTP is used in FTP. The security system is very high in FTP as compared to HTTP. SFTP stands for secure file transfer protocol, SFTP is a secure way to transfer the files from one network to other. FTP and SFTP work the same, but the only difference is that SFTP provides more security than FTP. The password that is required in FTP is just a plain text which can cause a threat, so SFTP introduced a secure channel to transfer the files. There a protocol that is SSH that is secure shell protocol that is a program in UNIX. A secure connection between client and server is created in SFTP using SFTP.

Key Differences

  1. Telnet allows a client user to login to the remote server to access its resources whereas FTP is a file transfer protocol that does not provide a secure channel to transfer files.
  2. Port number of telnet is 23 whereas Port number of FTP is 20.
  3. Remote login is not required whereas Remote login is required.
