What is Interrupt Driven I/O? | Operating System Tutorial | #UGCNET #GATE #BCA

Learn how Interrupt-driven I/O works in Operating Systems and Computer Architecture. In this Hindi tutorial, we explain the step-by-step process of how the CPU handles I/O requests using an Interrupt Controller and the different types of I/O Buffering. [What you will learn in this video] In this video, we cover: ✅ Basic Mechanism of Interrupt I/O ✅ Role of I/O Controller & Status Registers ✅ Difference between I/O Controller and Interrupt Controller ✅ I/O Buffering Techniques: Single Buffering Double (Dual) Buffering Circular Buffering [Timestamps] 00:00 - Introduction to Interrupt I/O 00:16 - How CPU sends I/O Requests 01:31 - Understanding Controller Buffers 02:18 - Interrupt Request vs Acknowledgment 04:15 - Internal Components (Status & Data Registers) 07:58 - I/O Buffering Techniques 08:17 - Single Buffering Explained 08:39 - Double Buffering Explained 09:42 - Circular Buffering Explained 10:08 - Summary & Quick Revision #OperatingSystem #InterruptIO #IOBuffering #ComputerOrganization #HindiTutorial #UGCNET #GATE #BCA #CSE #EngineeringExams #UGTutor
