dual core questions?

Question

im basically confused with the terms
intel core
intel core2
dual 2 core
and dual core

what do all these mean and what is the difference between all these>?

Answer 1

Intel Core (Solo) - One processor one one chip - the slowest of the four

Intel Core 2 - Two processors on one chip - the fastest of the four

Dual 2 core - this is probably refering to the fact that there are Two chips each with two processors on them each effectively 4 processors (theoretically faster than the core 2 but expenside)

dual core - two processors on one chip, the middle ground of the four things here.
