ddr266/pc2100 and ddr333/pc2700 are interchangeable.
Yes.
DDR and DDR2 slots are different (different pin density and different notch location). Putting a DDR2 stick in will be impossible, and even if you did manage to jam it in, it wouldn't work. Stick to what the tech support people tell you and it'll work just fine.

Same as any other slot, to allow the board to work with the card in the slot. Very outdated slot.
Yes it will. I have 512 MB PC100-322S installed and working with 2x256MB PC133-333 on my G4 Mac.
they dont work at all....
An SD Card will not work in a Compact Flash or Microdrive slot. You need to have an SD Card drive slot or a multi format memory reader which is compatible with SD Cards.
No. MMC is too large to fit in a mini-SD slot. It will work, however, in a standard SD slot.
Yeah. It doesn't matter what corporation it is, Samsung or Nokia. What matters the most is the phone, slot for the card. For example if in your nokia phone there is a SD card slot, then let's say a samung phone has some kind of other card slot it will not work. But if both will have SD card slot then it should work.
yes, providing the motherboard has the correct slot for it which is why slot standards exist.
Yes, but only Micro SD cards will fit in the TF slot
