What is Binary?

Binary is the system which a computer uses to represent the numeric values of 0 and 1.

How does Binary work?

0 and 1 represent every number there is. A computer only counts in 1 and 0 and binary is how it does it. Binary can either be represented by on or off. On is 1 and off is 0.

Below is an example of how binary addition works...


1+0= 1

1+1= 0 carry the 1 to the next column

Why do computers use binary?

Computers use binary as their form of counting and 1 and 0 is on and off. This form which computers use is called Binary.
