An 8-bit binary code allows for how many logical combinations?

An 8-bit binary code can represent a total of 2 raised to the power of 8 logical combinations. This is because each bit in a binary system has two possible states: 0 or 1. When you have 8 bits, the calculation is as follows:

(2^8 = 256)

This means that an 8-bit binary number can yield 256 different values or combinations, ranging from 00000000 (which is 0 in decimal) to 11111111 (which is 255 in decimal). Thus, the total number of unique combinations that an 8-bit binary code can represent is indeed 256.

The other options indicate incorrect totals based on the powers of two. While the numbers may seem plausible, they do not correspond to the calculation derived from 8 bits. Therefore, the correct understanding of binary combinations in an 8-bit system confirms that the answer is 256.
