Which of the following is not a binary number?
$ and $.
Computer MCQs for Competitive Exams- Step 1 (Binary Logic): Digital computing systems operate on dual-state electronics (on/off). This logic is mapped directly using a radix base of simple_quiz$, meaning each digit position in a binary string can only ever express a value of $ or $.
- Step 2 (Evaluation): Examining the number **202** reveals the inclusion of the digit simple_quiz$, which is an invalid digit that violates base-2 notation rules (belonging instead to base-10 decimal or higher numbering systems).
- Incorrect Options:
- 001 is a perfectly valid 3-bit binary sequence containing only zeros and ones.
- 101 is a valid binary integer representation (equivalent to the decimal number $).
- 110 is a valid binary integer sequence (equivalent to the decimal number $).

Computer MCQs for Competitive Exams- Multiplexer is incorrect because a multiplexer merges multiple independent data streams into a single high-speed transmission channel, rather than executing analog-to-digital transformations.
- Modulator is incorrect on its own because it only covers half of the bidirectional communication cycle, representing the digital-to-analog outbound phase.
- Demodulator is incorrect on its own because it only accounts for the incoming analog-to-digital processing phase.
