Last year, the firm unveiled a chip with 80 processing cores and capable of more than a trillion calculations per second (teraflops) (…)

Teraflop comes from tera (1012) and FLOP. Tera comes from the Greek word for "monster", which was chosen because it looks like the Greek prefix for "four" (tera is 10004). It comes after giga (109), which means "giant" in Greek; would a monster really beat a giant?
FLOPS is the acronym for FLoating-point OPerations per Second. I read the definition five times and still don’t understand what they are.
What’s next? Well, petaflops (1015), exaflops (1018) zettaflops (1021) and yottaflops (1024), of course! See here the whole list of SI (Système International) prefixes.
