And its also mentioned this terminal is for the X Window.

  • Functionality of xterm is same because of the same shell by the way, like i mentioned in my answer Aug 5, 2015 at 6:25

The xterm package has been around since before the original days of X Window, a popular display server.

xterm doesn’t require many resources (such as memory) to operate. Because of this, the xterm package is still popular in Linux distributions designed to run on older hardware.

It can also emulate older terminals, such as VT102,VT220, and Tektronix 4014 terminals (these are the terminals used in 1980-1990's).

To emulate VT100 terminal ,simply type

xterm -ti vt100

By definition xterm is a terminal emulator for the X Window System. Since Ubuntu by default relies on X11 graphical server for any graphics - that's why xterm comes with Ubuntu. Now, unless you manually change it, both default terminal and xterm should run your bash shell, which is what actually interprets commands. Without shell, terminal emulator is basically not going to work.

xterm actually is the original terminal emulator and many modern emulators strive to emulate its functionality and extend it.
