Information and data is communicated through a binary system in a computer. Imagine if you speak English and you try to communicate with someone who speaks Chinese, there would be a break down in communication because one party can't understand the other. The language of a computer works the same way. Binary codes and predetermined sets of 1's and 0's. For example if you type in the letter "A" in the computer, automatically that symbol is assigned a code. When you look at the entire scope, every function on the computer is communicated by binary codes. Binary functions are also used to operate at a "on" and "off" function. Take for instance a processor. The traces that run to and from a processor are set in binary form, meaning they alternate from on and off with the help of a system clock. A system clock controls the tempo of how data is received and exported. Just think of kids jumping rope; when they jump up in the air that acts as "on" when they come down that acts like "off". The rope acts as the timer.
