Computer must reduce everything to 0’s and 1’s A zero or a one by itself is called a bit. How many bits a computer is allowed to use determines how many unique things it can remember. 1 bit = Computer can remember 2 unique things The 2 nd column in base 2 is 2. 2 bits = Computer can remember 4 unique things The 3 rd column in base 2 is 4 3 bits = Computer can remember 8 unique things The 4 th column in base 2 is 8 4 bits = Computer can remember 16 unique things The 5 th column in base 2 is 16 Etc.
