Computer Organisation and Architecture for Computer Science Exams

Understanding how hardware executes software is the cornerstone of computer science and a critical component of major competitive examinations like the GATE. This text-based course bridges the gap between high-level programming and low-level hardware execution, breaking down complex engineering concepts into digestible, written explanations. You will transition from basic digital logic to understanding modern processor design and memory management. What you'll learn: Understand core computer arithmetic, instruction formats, and addressing modes; Analyze CPU control unit design, including hardwired and microprogrammed control; Master memory hierarchy, cache mapping techniques, and virtual memory management; Learn input-output organization, including programmed I/O, interrupts, and direct memory access (DMA); Apply pipelining concepts, calculate speedup, and resolve pipeline hazards; Practice solving typical exam-style questions and previous year problems step-by-step. The course begins with essential terminology and fundamental architectural concepts, then guides you systematically through data representation, processor design, and memory organization, concluding with modern performance-enhancement techniques. This course is designed specifically for beginners, computer science students, and exam aspirants with no prior background in hardware architecture.
