CBecause computers cannot understand more than two digits
DBecause binary numbers are shorter than decimal numbers
Step-by-Step Solution
Solution:

  1. Step 1: Understand the basis of binary system in electronics

    Digital electronics use two states: ON (1) and OFF (0).

  2. Step 2: Connect binary digits to electronic states

    Binary digits 0 and 1 represent these two states, making it reliable for computers.

  3. Final Answer:

    Because digital electronics have two states: ON and OFF -> Option A

  4. Quick Check:

    Binary digits match electronic ON/OFF states [OK]
Quick Trick: Binary matches ON/OFF states in electronics [OK]
Common Mistakes:
MISTAKES
  • Thinking binary is shorter than decimal
  • Assuming computers can't handle more digits
