Sorry the questions were so PC oriented, PKRWUD.

1. PC2100 DDR memory; what is the "2100" in reference to? How is that number derived?
andy669 was completely correct.

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?
A 50X cd-rom only reads at 50X at the very outside of the disk, because data is going by the read head at a higher rate because of the higher circumference (366mm vs. 135mm in the inside). The ratio of these two is .37:1, so with simple math you can find that the inner read speed is 18.5. NEC coined the whole "X" thing.

3. What does PCI stand for? AGP? ISA? AMR? CRT? (abbreviations are fun!)
You guys were both right about these. AMR slots are useless, but some of the big companies use them.

4. How is a TCP connection establish (what is sent first)? What packet is sent to acknowledge the receipt of data? What flag for terminating the connection?
A tcp connection is established with a SYN packet, data is acknowledged with ACK, and the connection is terminated after the sender sets the FIN flag on the last data packet

5. What socket did the Pentium Pro processor use? The normal Pentium?
PKRWUD, you're correct, they both use ZIF sockets.

6. Which way should the power supply fan blow (in or out) according to the original ATX specifications?
As stupid as it sounds, the original specs called for the PSU fan to blow its hot air IN, onto the processor. I've never seen this done.

7. What is the name of the power plug that large devices use (hard drives, cd-roms, etc.)?
It's a Molex connector

8. How many pins are in an ATA-33 IDE cable? How many conductors (wires)? What about ATA-66/100?
An ATA-33 cable has 40 pins, and 40 accompanying wires; an ATA-66/100 cable has the same 40 pins, but adds 40 more conductors between each pair of data wires, that are simply grounds.
