Question

. A register in a computer has a of bits. How many unique combinations can be stored in the register?

Answer 1

Answer:

The number of unique combinations stored in the register totally dependent upon the number of bits the register can hold.

Explanation:

Suppose if the register is 2-bit.Then it can have (2²) 4 unique combinations of the bits and those combinations are 00,01,10,11.For a 3 bit register there are (2³) or 8 unique combinations those are 000,001,010,011,100,101,110,111.So for a n-bit register there can be 2ⁿ unique combinations there.
