Match List-I with List-II: List-I A. Real-Time OS B. Time-Sharing OS C. Batch OS D. Dual-Mode Operation List-II Guarantees execution within strict, fixed time constraints. Executes multiple programs simultaneously by switching CPU rapidly. Groups similar jobs together to execute without human intervention. Uses User Mode and Kernel Mode to protect system resources.

A - 1, B - 2, C - 3, D - 4 Explanation: A. Real-Time OS 1: Real-Time OS strict time limits/deadlines ke under tasks ko execute karne ki guarantee deta hai (jaise air traffic control ya medical systems me). B. Time-Sharing OS 2: Time-Sharing OS CPU ko alag-alag tasks ke beech rapid speed se switch karta hai jisse har user ko lagta hai ki system uske liye simultaneously chal raha hai. C. Batch OS 3: Batch OS ek jaise tasks (similar jobs) ko ek saath group karke automated tarike se bina human interaction ke execute karta hai. D. Dual-Mode Operation 4: Dual-mode execution system resources aur hardware ko unauthorized access se bachane ke liye User Mode aur Kernel Mode ka upyog karta hai.
