These commands all open up a 25-line, 80-character-wide terminal window, located
100 pixels below the top of the screen and 50 pixels to the right of the left edge of the
screen:
$ gnome-terminal --geometry 80x25+50+100 # GTK+
$ konsole -geometry 660x475+50+100 # Qt
$ xterm -geometry 80x25+50+100 # Xt
Notice that the konsole size is specified in pixels, which the xterm and gnometerminal
sizes are specified in characters.

Applications
From before X was released up to a few years ago, character terminals were in widespread
use. These devices had a character-only display, typically 80 columns wide by
24 or 25 rows high, and a keyboard. Each model of terminal varied in its display
capabilities??”some had color, some offered varying font sizes for 132- and 40-
column display modes, and some could draw underlined and bold text??”and in its
keyboard layout. These terminals were typically connected to the host computer
through a serial cable, which required as little as 3 wires and could be over 100
meters long (300 foot). Modems, designed to work with serial interfaces, could be
used to extend this distance over the dial-up telephone network.
