This course introduces students to the fundamental concepts of computer architecture and its applications. It provides a clear understanding of how computers are structured, how they execute programs, and how data flows through different components. The course bridges the gap between hardware and software, helping students understand how electronic circuits support computation and how system components interact to perform tasks efficiently. Through theoretical explanations and practical exercises, students will learn how a computer processes information, how memory and I/O systems are organized, and how processors execute instructions. The course also highlights real-world applications of computer systems in science, engineering, and daily life.
