There is an old engineering adage, that the complexity of a system arises, 
not so much from the number of individual components, as from the number 
of potential interactions between them.

If you have a box full of screwdrivers, then all you have is a box full of 
screwdrivers.

If you have a computer system made up of a bunch of modules interacting 
with each other, then you could have, potentially, quite a complex system 
indeed.

Look up the term “combinatorial explosion” to learn more.
