2.1 CLI - Remote Access Tools
Telnet is a rudimentary example of CLI. Telnet runs on port 23 TCP, and SSH which is more secure counterpart of telnet runs on port 22 TCP.
SSH stnads for Secure Shell Protocol. This adds layers of authentication and encryption. SSH uses public-key cryptography.

TeamViewer is not pre-installed on operating system. But Microsoft Remote Desktop Connections is intergrated with OS. So this software can be misconfigured. Misconfiguration results in errors.
In our case, Administrator has no password. So I gained access so easily without hard effort.
