Course Introduction
Computer Architecture
Review Questions
Computer Architecture explores the fundamental concepts and design principles that form the backbone of modern computer systems. The course covers topics such as processor design, instruction set architectures, memory hierarchies, input/output mechanisms, and performance evaluation techniques. Students will learn how hardware components interact, how design choices impact system efficiency, and the trade-offs involved in contemporary architectural decisions. Through theoretical foundations and practical examples, the course provides a comprehensive understanding of how computers execute instructions and manage data efficiently.
