Definition check in digital systems: “Binary means having two states or values.” Assess whether this definition is accurate in the context of digital electronics and computing.

Introduction / Context:
The binary system forms the foundation of digital logic, encoding, and computation. Clarifying the meaning of “binary” ensures accurate reasoning about signals, storage, and algorithms in digital platforms.

Given Data / Assumptions:

• “Binary” refers to the base-2 numeral system and to two-level logic states.
• Typical voltage mapping: logic 0 and logic 1 within defined thresholds.
• Applies to combinational and sequential circuits alike.

Concept / Approach:
Binary denotes two possible symbols in a numeral system (0 and 1) and two discrete logic levels in hardware. Computation in digital electronics uses Boolean algebra where variables assume one of two values. All higher abstractions—bytes, words, instructions—are built from binary bits.

Step-by-Step Solution:

Verification / Alternative check:
All standard data paths, storage arrays, and instruction encodings use bits. Voltage thresholds and noise margins in logic families are specified around two-state operation.

Why Other Options Are Wrong:

• Incorrect / arithmetic-only / unsigned-only / ambiguous: Binary applies broadly to logic and numbers, signed or unsigned, so these limitations are unfounded.

Common Pitfalls:
Confusing binary with multi-level signaling techniques; even then, system interfaces ultimately resolve to binary logic values for computation and storage.

Final Answer:
Correct
