A. 16
B.56
C.128
D.256

Answer 1

Answer:  The correct option is (D) 256.

Step-by-step explanation:  Given that a computer is a string of 8 characters, and each character is a 0 or a 1.

We are to find the number of possible computer bytes.

There are two options for each of the eight characters, that is 0 or 1.

Therefore, the total number of possible computer bytes will be

$n=2\times2\times2\times2\times2\times2\times2\times2\times2\\\\\Rightarrow =2^8\\\\\Rightarrow n=256.$

Thus, there are 256 possible computer bytes.

Option (D) is CORRECT.

Answer 2

The correct answer is D. because the number of possible computerbytes is 2^8 = 256.
