What is the purpose of Telnet and how does it work?

Telnet is a network protocol used to establish a connection with a remote host for the purpose of accessing its resources, such as a server or networking device. It allows users to log in remotely and interact with the command-line interface of the remote system.

When a user initiates a Telnet session, a connection is established between the local and remote hosts through the network. The user can then enter commands on their local machine, which are transmitted over the network to the remote host, where they are executed. The results are sent back to the local machine for the user to view.

Overall, the purpose of Telnet is to facilitate remote access and management of network devices and servers. It provides a simple and interactive way for users to control remote systems without physically being present at the location of the device.
