Kylie:
As to question number one, consider:
A. 24 hard drive letters and you're out of hard drives.
B. Usually, only 2 IDE drives per IRQ channel, Master
and Slave drives -- and with the normal usage
of IRQs (being the System Timer, Keyboard,
Cascade, Com 1 and 2, Soundcard, Floppy, LPT1,
RTC and Math Coprocessor) -- you would only have
6 open IRQs, for a total of 12 IDE drives. Subtract
one if you have one CD-ROM drive.
C. Power Supply wattage is also a limitation; subtract
current usage for every device except hard drives,
then divide the remaining wattage by the power
consumption of a single IDE hard drive to get maximum
number of hard drives supported, power-wise.
I defer the Network questions to our Network collegues.
Is this a take-home quiz? <g>
