Hi Alastair,
James Devenish perhaps can answer more technically than I.
Short answer, no effective difference.
A restart (at least in a Unix environment, which the Mac is), dumps
EVERYTHING, and boots fully from a zeroed state.
ALL processes are released and reinitiated from scratch.
Even if there were anything residual in any cache, it would be
overwritten anyway when the system was being restored.
A shutdown simply powers down the machine almost entirely and does
not attempt to start the operating system again until you press the
power button.
A restart simply ends your session in Mac OS X, shuts the operating
system down, and then re-loads the operating system again.
Cheers,
Ronni

Thanks Ronni for that useful summary. One question - for the
purposes of clearing all the gibbledygook, is a restart the same as
a shutdown?

I only occasionally shut down (thunderstorms, outages); I use a
UPS. The computer is on 16-17 hours daily; manually put to sleep
at night. I sometimes put the unit to sleep during the day if I
know it will be several hours before I use it. The display is set
to darken after 3 minutes. I pretty closely follow the guidelines
in the article cited by Ronni. I have have followed this routine
for many years.

Good morning all,
Indulge me in another chapter in the ongoing debate about
sleeping computers, if you will.
My home iMac is turned on in the morning and shut down at the end
of the day. In between, I set it to sleep manually when I'm away
for more than a few minutes.
What practice do you follow? I know the user guide says to shut
down when the computer is not in use for more than a few days,
but I've always thought giving it a break overnight was a good
idea. I'm keen to learn the opinions of other Mac users.
Thanks in advance,
Clinton
