Digital Logic and Computer Design
Exam Materials
Course Introduction
This course introduces the fundamental concepts of digital logic and its crucial role in computer design. Students will learn about number systems, Boolean algebra, combinational and sequential logic circuits, and how to analyze and design these circuits using logic gates, flip-flops, and other hardware elements. Emphasis is placed on the design and optimization of arithmetic circuits, memory units, and basic processor components. Through theoretical study and hands-on laboratory exercises, students gain the foundational knowledge needed to understand modern computer architectures and develop essential skills applicable to engineering and computer science professions.

Q2) Why is the computational capacity/speed of quantum computers much higher than conventional computers for certain types of tasks? Should all computers be quantum computers?
Answer: The qubit enables the computer to store and process multiple data items at the same time.As a result, many computations can be performed on many related data items simultaneously, yielding much greater parallelism and performance than conventional computers.
All computer don't need to be quantum computers because not all computational problems benefit from the additional power of quantum computing.Also, quantum computers are currently much more expensive than conventional computers.As long as the cost difference remains, quantum computing applied only to problems where its cost-effective.
