I just bought a 20 inch imac, that was supposed to have a 320gb hard drive.....

turns out it is a 300 gb hard drive.... is this common? If so, i don't care...and to be honest, i'm so happy with the computer i could care less....but want to know if this is something that could possibly be changed????:eek:

they advertise in base 10 but the computer reads it in base 2

aka
1000mb=1 gigabyte is how the advertise it

however, a computer defines a gigabyte as
1gigabyte=1024mb

Apple and every HD manufacturer who use this marketing technique put a little tiny asterisk next to the drive says that refers to some 4 point font about the drive size. How did you miss that? ;)

same with UPS sets

they are sold in VA ( Volt Amps ) not watts

in AC Watts are V * I * PF ( Power Factor typically 0.8 )


ie it looks better than it is same for HHD's

FYI, the answers you seek could have been quickly found via Google.

Not the same case at all, as it's not a marketing but a functional measurement of apparent power. BTW, the PF is more in the .6 to .65 range (which is the de facto "standard" for common UPS's). Granted, it makes it a little more challenging to determine the right size, but for non-reactive loads (such as PC power supplies) is considered an appropriate measurement.

And the apropriate meaning of kilo, mega, giga, etc. is powers of 10.

For powers of 2, kibi, mebi, gibi, etc. should be used.
