Identify the statement about binary representation that is true.
Binary states are represented inside computers by varying levels of voltage representing 0, 1, 2, and 3.
The right-most bit in an unsigned binary integer represents the most significant bit (MSB).
Computers use binary because their electronic circuits consist of transistors acting as switches that are either on or off.
An 8-bit binary number can represent a maximum of 512 distinct values.
