• A. 0, 1
• B. 1, 2
• C. 0, 1, 2
• D. 0, 2

Hint:

The prefix "bi-" means two. The binary system uses two digits (0 and 1). The decimal system (from "deci-" for ten) uses ten digits (0-9).

Answer 1

The Correct Option is A

Step 1: Define the binary number system. The binary system is a base-2 number system. This means it only uses two distinct symbols to represent numbers.
Step 2: Identify the symbols. The two symbols used in the binary system are 0 and 1. Each digit in a binary number is called a "bit".
