### Understanding Hexadecimal and Bytes **Question:** If a byte is represented by a hexadecimal number, how many hexadecimal digits does it take to encode the 8 bits of a byte? **Explanation:** Recall that a hexadecimal digit is one of the following: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F **Answer Options:** - ○ 2 - ○ 3 - ○ 5 - ○ 1 - ○ 4 ### Explanation: A byte consists of 8 bits. In a hexadecimal system (base 16), each digit represents 4 bits (since \(2^4 = 16\)), which is why two hexadecimal digits are needed to represent the 8 bits of a byte. For example, the byte 11111111 in binary is FF in hexadecimal. Therefore, the correct answer is 2.
