What is Telnet ?

Telnet is the user command for accessing remote computers and a TCP / IP protocol underlying it. Telnet can remotely access someone else's computer from an administrator or another user. The protocols HTTP and FTP on the Web permits you not to log in as a user of the computer, but to request specific files from remote computers. You can log on to the specific application and data on that computer with Telnet as a regular user with all the privileges you could have given. 

In other word we can say,Telnet (TN) is a  protocol and software program used to access remote computers and terminals via the Internet or a TCP / IP computer network. In 1969, Telnet was designed and standardized by the Internet Engineering Task Force (IETF) as one of the first Internet standards.

How telnets work?

Telnet gives users a two-way text-oriented, interactive communication system that uses an 8-byte virtual terminal connection. The user data is interspersed in the band with telnet control protocol (TCP) information. Telnet was often used for remote function execution on a terminal. 

By using the Telnet protocol, the user connects with the server, which means entering the command prompt for the Telnet port, using the syntax telnet. The user then performs commands on the server with the Telnet prompt by certain commands. The user terminates a Telnet command with Telnet to terminate a session and log out.
