Well thank you. I now feel remarkably stupid. We Mac folk don't study these things very much

.
Actually, your questions kinda confused me a bit. Your TCP question has me torn between the OSI and modem signals. Anyway, here's my input.
2. A "50X" cd-rom drive (which one can assume is CAV) reads at what speed on the innermost portion of the disk? What does the "X" moniker mean? What company coined the term?
I can't tell you the exact speed, but I know that the disk speed remains the same, but the read speed slows down as the laser gets closer to the center.
X = multiplication of 150KBps transfer rate. For example, 50X means it has a transfer rate of up to 7500KBps (50 X 150KBps)
3. What does PCI stand for? AGP? ISA? AMR? CRT? (abbreviations are fun!)
PCI = Peripheral Component Interconnect
AGP = Accelerated Graphics Port
ISA = Industry Standard Architecture
AMR = ???
CRT = Cathode Ray Tube
5. What socket did the Pentium Pro processor use? The normal Pentium?
Pro = Socket 8
Norm = A ZIF Socket 7
6. Which way should the power supply fan blow (in or out) according to the original ATX specifications?
Blows the hot air out.
8. How many pins are in an ATA-33 IDE cable? How many conductors (wires)? What about ATA-66/100?
40
Take care,

P.S. believe it or not, i passed my A+ with killer scores last February. How about some OS questions.
