Question

A notebook computer is set up to take maximum advantage of power saving features including shutting down the display and the hard disk after periods of inactivity. A user sometimes runs UNIX programs in text mode, and at other times uses the X Window System. She is surprised to find that battery life is significantly better when she uses text-only programs. Why

Answer 1

The reason is that the windowing system consumes significantly more memory and virtual memory than the text mode.

Step-by-step explanation:

The reason behind the occurrence of this is that the windowing system consumes significantly more memory and virtual memory than the text mode. As a result, this reduces the likelihood of the hard disk becoming inactive for long enough for it to be powered down by itself with no direct human control, i.e. automatically.
