Which of these is a main reason computers use binary instead of decimal?

ABinary signals are less affected by noise

BDecimal numbers are easier to store

CBinary requires more complex hardware

DDecimal uses fewer digits

Step-by-Step Solution

Solution:

Step 1: Consider signal noise impact
Binary signals (two states) are less likely to be confused by noise than multiple voltage levels needed for decimal.
Step 2: Evaluate hardware complexity
Binary hardware is simpler and more reliable than hardware for decimal representation.
Final Answer:
Binary signals are less affected by noise -> Option A
Quick Check:
Binary reduces noise errors [OK]

Quick Trick: Binary is simpler and less noisy than decimal [OK]
