Bits and Bytes
✘
A computer stores all DATA as
numbers of 0 and 1
✘
The smallest unit of information is
called a BIT

Binary and decimal
✘
Computing machines understand digits of 0 and
1 while people use digits from 0 to 9.
✘
The digits from 0 to 9 are called decimal
numbers. So to use the decimal numbers
computers convert decimal numbers to binary.
