Unit 8: Information and Communication Technology Q1. Assertion (A): Cloud computing helps in reducing the cost of owning and maintaining IT infrastructure. Reason (R): Cloud computing offers resources on-demand and follows a pay-as-you-go model. Codes: A. Both (A) and (R) are true, and (R) is the correct explanation of (A). B. Both (A) and (R) are true, but (R) is not the correct explanation of (A). C. (A) is true, but (R) is false. D. (A) is false, but (R) is true. Answer: A ✔ Explanation: ▪️ Cloud Computing allows users to access computing resources (like servers, storage, applications) over the internet. ▪️ It eliminates the need for physical infrastructure, reducing capital expenditure and maintenance costs. ▪️ It follows the pay-as-you-go model, meaning users pay only for what they use. ▪️ Thus, (A) is correct as it highlights the cost-saving benefit, and (R) correctly explains it as it provides the reason — on-demand access and pricing flexibility. ▪️ Therefore, option A is the correct answer.
