Question of Data Sizes

What is the relationship between the size of unsigned int (32 bits) and its maximum value(4294967295)?

Perhaps this table of the powers of two will help you understand.

unsigned long

2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 =

4,294,967,296 (0 - 4,294,967,295)

It help me a lot. Thanks!
