Explanation: Telnet is a protocol used to connect to remote computers over the Internet or a local network. It allows the user to access the command-line interface of the remote computer and execute commands as if they were sitting in front of it. Therefore, if you want to connect to your own computer through the Internet from another location, Telnet can be used. However, it's important to note that Telnet is an unencrypted protocol and can expose your login credentials to potential eavesdropping, so it's recommended to use a secure protocol such as SSH instead.
