It seasier for computers to count in the binary system becausr there are only two states. 0 or 1, off or on, low voltage or high voltage. However you want o think of it. Think of a light switch, it only knows two states, either its off or its on. Its the same reasoning for computers working in the binary system. The computer doesnt have to, or need to keep track of ten different states (0 - 9) just two states (0 -1) off or on.
