Any information in the computer is encoded as 1's and 0's. For example, if you press a key on your keyboard, a series of 1's and 0's is sent to the computer. Even pictures, sounds, videos, etc. can be encoded as 1's and 0's - after all, they are all types of information.
Binary is easier for the computer to understand. It is also easier to handle and is not costly.
