crossfire is a technology used in amd card that employs the use of two or more(upto 4) amd cards that must be of similar;
1.model
2.memory
after using crossfire it should double the performance.(theoretically)
in practice it almost doubles your performance(just not the exact double,almost comes close)

Sli is the same technology used by nvida to do the same

result after crossfire:
1.More power consuption
2.more heat output
3.more perfomance

requirements:
same model card of same memory
a good power supply
proper cooling
2 pcie slots express slots

Crossfire (and Nvidia's counterpart, SLI) allows two GPUs to work together, thus increasing the graphical processing power your system has.
It doesn't work with any two cards, for Crossfire you need two cards of the same generation and for SLI you need two card with the exact same GPU.

Crossfire is where you have two amd (or radeon) graphics cards together in one computer, it is useful as it allows you to run two graphics cards for increased performance. It is only really useful for high end cards when there is no higher single gpu option as it introduces some odd problems and does not double the performance compared to one card. Nvidia's version is called SLI. The actual techinical way it works can be easily found (google is your friend) but basically you put two crossfire compatible cards in a crossfire compatible motherboard and enable crossfire mode and it works (some models of cards require a crossfire "bridge" connecting the cards)
