Trackball Basically an upside-down mouse. Rather than sliding the
entire device to direct cursor movement (as with a mouse),
the trackball rests in one place. The tracking ball is exposed

obvious advantage of the trackball over a mouse is that it
doesn't require the space for the pad on which to run.

power supply
A device designed to provide back-up power when power
from the AC outlet is interrupted. An uninterruptible power

power-down your computer. Without it, your computer
automatically shuts down as soon as it loses power, causing
you to lose all of your unsaved work.
