Computers are great because they do exactly what they're told, very fast. But
sometimes, we need things done faster than a computer can do them. What can we
build that's faster than a computer?

If you want to work on something, it will be faster if your friend does one
part while you do another. Two people working on different things at the same
time are faster than one person doing everything alone.

Computers work the same way: If you can break up what you want the computer to
do into smaller things, and then get different computers to work on those
