Daily interview question: What is the use of Telnet and ssh?

Telnet is a network protocol that allows a user to communicate with a remote device or server over a TCP/IP network. Unlike SSH, Telnet does not provide secure communication, as it transmits data, including passwords, in plaintext. Telnet is still used in certain environments, primarily for specific administrative and troubleshooting tasks
Secure Shell (SSH) is a cryptographic network protocol used for secure data communication, remote shell services, and command execution between two networked computers
