§ Information is handled in a computer by electronic/ 
electrical components
§ Electronic components operate in binary mode (can 
only indicate two states – on (1) or off (0)
§ Binary number system has only two digits (0 and 1), 
and is suitable for expressing two possible states
§ In binary system, computer circuits only have to handle 
two binary digits rather than ten decimal digits causing:
§ Simpler internal circuit design
§ Less expensive
§ More reliable circuits
§ Arithmetic rules/processes possible with binary 
numbers
