Question 72

Computer Awareness Input/output devices Easy

Given below are two statements: one is labelled as Assertion \( A \) and the other is labelled as Reason \( R \) .

Assertion A: Binary information is represented in digital in terms of 'zeros' and 'ones'.
Reason R: Digital computers are electronic devices, which operate using electrical voltages.

In the light of the above statements, choose the most appropriate answer from the options given below:

(A) Both A and R are correct and R is the correct explanation of A
(B) Both A and R are correct and R is not the correct explanation of A
(C) A is correct but R is not correct.
(D) A is correct but R is correct.
✓ Correct Answer: Option A Verified Solution

📘 Step-by-Step Solution & Detailed Explanation:

Assertion A is true: digital systems represent all binary information as 0s and 1s.

Reason R is true: digital computers are electronic devices that work with electrical voltages.

R also explains A. Electronic circuits can reliably tell apart two voltage levels (low and high). These two levels are used to represent 0 and 1, which is why information is stored in binary.

Answer: (A) Both A and R are correct and R is the correct explanation of A
