Explanation

Telnet is a text-based computer protocol that allows users to remotely access and manage a computer or network device. It uses a command-line interface (CLI) to send and receive text-based commands and responses. Telnet is a client-server protocol, where the user's device acts as the client and the remote device acts as the server.

Telnet is typically used for:

• Remote access to servers, routers, and other network devices
• Command-line interface (CLI) access to network devices
• Troubleshooting and debugging network connections
• Remote execution of commands and scripts
