Data Representation (cont.)
	ä Unsigned integers ä Interpret binary value as a base 2 value 1   0   1  0  0  1                        |---> 20  = 1                     |-----> 21    = 0                 |--------> 22    = 0             |-----------> 23    = 8        |---------------> 24   = 0  |-------------------> 25    = 32                            Sum is 41 decimal (base 10) ä Size of register determines how many integers can be encoded this way ä Some times systems have double integers or longs for double the width and more integers to be represented
