Most of the Linux Distro ships with GUI i.e Graphical User Interface and in order to to communicate with the operating system we need a terminal emulator to interact with the shell.
You may have encountered these emulators in the form of Gnome-terminal or konsole and these are named as terminal in your distro. You can access them by shortcut keyboard keys by holding
shift+alt+t or super-key+t both works depending on your distro. You can also access the main terminal i.e ttyl which is basically a non-gui look for your system. You can access it by holding
ctrl+alt+f1 or ctrl+alt+f6 these will open login prompt to access your session for the further work.
To exit it hold alt+f1 or alt+f7.
