Why do computers use binary instead of decimal numbers?

ABecause decimal numbers use less power

BBecause binary uses only two states, making it simple and reliable

CBecause binary uses ten digits like humans

DBecause decimal numbers are faster to process

Step-by-Step Solution

Solution:

Step 1: Understand the nature of binary and decimal systems
Binary uses two digits (0 and 1) representing off and on states, while decimal uses ten digits (0-9).
Step 2: Recognize why two states are preferred in computers
Two states are easier to detect electronically and less prone to error, making binary simple and reliable for computers.
Final Answer:
Because binary uses only two states, making it simple and reliable -> Option B
Quick Check:
Binary simplicity = reliability [OK]

Quick Trick: Binary uses two states for simplicity and reliability [OK]
