What is the difference between telnet and ftp

FTP uses port 21 for control connection and port 20 for data connection. In the entire FTP session, the control connection remains activated while data connection opens for transferring files and then closed when the file is completely transferred. 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.

As against, FTP uses encryption methods which implement security. In Telnet the user needs to log in first in the remote machine then any operations can be performed. While in case of FTP port numbers 20 and 21 can be used to establish connection and perform file transfer operations. On other hand as FTP has two ports available so FTP establish two connections, one is for control command and another is for data transfer.

In System Testing since it is performed by group of testers, it would contain more negative test cases. 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.

Port Number The port number of telnet is The port number of FTP is Security The telnet may have a security concern. It is more secure and safe than telnet. Remote Login it is not required in telnet to access remote login. The remote login is required in FTP to access it.

What is Telnet? The same process is followed to transmit the response from the server to the client. They were designed to allow effective communication between remote operating systems. The first is responsible for allowing a more or less secure transfer of files from one system to another. It also makes it easy to upload and download digital files from web pages. Allows users to access remote servers through their command protocols.

By operating with a single established connection, it helps clients access data stored on distant servers. The security level of each is also quite the opposite of the other. These fundamental differences between the two make them quite antagonistic to each other, although both were developed with similar intentions in mind. Your email address will not be published.
