Because we have eight fingers and two thumbs, it seems natural for human beings to count in tens. It is just as natural for a computer to count in twos, for it has to decide between ‘yes’ or ‘no’ for every step in a process.
In everyday numbers, the digits from 0 to 9 are read from left to right and are based on the power of ten. For example, 110 is one hundred, ne ten, and no units.
The binary system uses only two digits: 0 and 1. Numbers are read from right to left and are based on the power of two. Moving from the right, each digit doubles in value, 1, 2, 4, 8, 16, and so on.
Words fed into a computer are stored as binary numbers. If text such as LOAD”FILE in BASIC, computer language is keyed in, the word LOAD could be processed.
