A) What is the difference between an s754 and s939 processor?
[ They're different sockets. 754 has 754 pins; 939 has 939 pins; 754 used to be used for AMD Athlon 64 xx00+ and 939 for the FX ]
B) What is newer: AGP or PCI Express?
[ PCI Express ]
C) What's the min. voltage you should have for a 64-bit system's Power Supply?
[ Mine works with 400 watt. And AMD Athlon 64 takes about ~100 watts, but then you'll need a mobo, gpu, etc ]
D) What's a Heatsink?
[ It's something you stick on your proc. The heat then goes from the cpu to the heatsink. Most of the time there's also a fan on top of the heatsink to cool the heatsink, but if you have a proc that doesn't get hot, you could be able to do without (not with an athlon 64!) ]
E) True or False: You should NEVER ground yourself before installing computer parts.
False (it is actually a good thing to do)
F) True or False: BIOS is required before you can start the computer.
True
G) True or False: 99% of the time, BIOS DOES NOT come with the Motherboard.
wtf, ofcourse it does! How were you going to boot without it? 
You can upgrade your bios by flashing it, though
H) What does CPU stand for?
Central Processing Unit
