CSUC101_Unit1_EVEN

A 12-bit system represents unsigned hexadecimal values. What is the result of incrementing FFF₁₆, and what does it imply?

• Result is 1000₁₆; 13-bit representation is now required.

• Result is FFF₁₆; value remains unchanged due to saturation.

• Result is 000₁₆; but no overflow occurs since it is unsigned.

• Result is 000₁₆; the value wraps around due to overflow.
