xterm is the standard terminal emulator for the X Window System. It provides DEC VT102/VT220 and Tektronix 4014 compatible terminals for programs that can’t use the window system directly.
wmii is the next generation of wmi. It is a highly customizable keyboard-and-mouse-driven X11 window manager that supports conventional, tabbed, and tiled window management with low memory usage and vi-like user interaction.
