I wanna know about what is console?

Answer 1

Console (also called terminal) provide a CLI (Command Line Interface), meaning a text-only virtual screen to connect to a computer in oposition to GUI (Graphic User Interface).

A GUI is running on a higher user interface level, and console/terminal is a way to access to a lower level, even inside a GUI, as if you avoid run a GUI.
It's helpful for accessing distant computers (servers), which doesn't need to use ressources to run a GUI (and often even doesn't have screen plugged, as they're intended to mainly be distant accessed).
