Binary numbers are combined in a sequence to form a '''byte'''. Bytes are used to represent '''numbers''' or '''characters'''. How does the computer know which bytes represent a number or a letter? That is the job of '''computer programs ''' that are created (including operating systems and application software) to perform that task.
