Do you think you are made from bits and bytes? Stop playing video games and spend some more time offline! Both atoms and bits are basic parts of matter. An atom is the smallest unit of any chemical element, still recognizable building block. A bit is the smallest unit of information, a symbol or signal that can have one or two values. Information technology represents these values as 0 and 1. Remember: you are made of atoms; your video game is made of zeros and ones.
