a number system with base 2, or only two values 0/1; also see Binary Numbering System

• A. Numbering System (Binary)
• B. Network Topology
• C. NetBIOS
• D. Network Cards

Answer: (A)

The concept being tested is recognizing a binary numbering system, which uses base 2 and only the digits 0 and 1. This is the fundamental way computers represent and process data, with each digit being a bit and combinations of bits forming bytes and larger values (for example, 1010 in binary equals 10 in decimal). Why this is the best choice: the description explicitly defines a numbering system that operates with two values, 0 and 1, and this is precisely what the binary system is. Other terms refer to network concepts or hardware, not a way of representing numbers, so they don’t fit the description of a base-2 numbering scheme.
