As humans, one way in which we are unique is our ability to communicate with complex language (arguably, science students possess this skill too).

Instead of the decimal system we count with, which uses the ten unique digits ‘0’ to ‘9’, computers ‘think’ only in ‘0’s and ‘1’s. This is because their hardware is controlled by tiny switches, which turn electrical current on or off. As it is difficult to control electrical current at such a microscopic level (switches can be as small as only 10x the size of an atom!),
