If a computer uses binary signals where 1 means ON and 0 means OFF, what would be the output if the input signal sequence is 1101?
AThe computer reads the sequence as four ON signals
BThe computer reads the sequence as ON, ON, OFF, ON
CThe computer reads the sequence as ON, OFF, ON, OFF
DThe computer cannot read this sequence
Step-by-Step Solution
Solution:

  1. Step 1: Interpret each binary digit

    Each '1' means ON and each '0' means OFF in the sequence.

  2. Step 2: Map the sequence 1101

    First digit 1 = ON, second 1 = ON, third 0 = OFF, fourth 1 = ON.

  3. Final Answer:

    The computer reads the sequence as ON, ON, OFF, ON -> Option B

  4. Quick Check:

    Binary 1=ON, 0=OFF sequence [OK]
Quick Trick: 1 means ON, 0 means OFF in binary signals [OK]
Common Mistakes:
  • Assuming all digits are ON
  • Mixing ON and OFF order
  • Thinking sequence is unreadable
