Homework Help: Questions and Answers: Which term describes a number in base 16, using the digits from zero to nine along with A, B, C, D, E, and F?
a) hexadecimal
b) bit
c) binary
d) byte
Answer:
First, let’s understand the question: Its about for a term that describes a number in base 16, using the digits from zero to nine along with A, B, C, D, E, and F.
Given Options: Step by Step Answering
a) Hexadecimal
- Hexadecimal is a number system that uses base 16, meaning it includes 16 distinct symbols. These symbols are the digits 0-9 (representing values 0 to 9) and the letters A-F (representing values 10 to 15). So, a number in hexadecimal can contain digits from 0 to 9 and letters A to F. This matches the description in the question.
b) Bit
- A bit is the smallest unit of data in computing, representing a binary value of 0 or 1. It is unrelated to base 16 or the use of digits and letters as described in the question.
c) Binary
- Binary is a number system with a base of 2, meaning it only uses two digits: 0 and 1. This does not match the description, as binary does not use digits from 0 to 9 or letters A to F.
d) Byte
- A byte consists of 8 bits and can represent a value between 0 and 255 in decimal. While a byte can be used to represent numbers, it is not a term that specifically describes a base 16 system with digits and letters.
Final Answer
Based on the above analysis, the correct answer is:
a) hexadecimal
Hexadecimal numbers are often used in computing because they provide a more concise way to represent binary data, where each hexadecimal digit represents exactly 4 binary digits (bits).
