FAQs on Introduction to Computer Architecture Video Lecture - Computer Architecture & Organisation (CAO) - Computer Science Engineering (CSE)

1. What is computer architecture and why is it important in computer science engineering?
Ans.Computer architecture refers to the design and organization of a computer's components, including the CPU, memory, and input/output systems. It is crucial in computer science engineering as it directly affects system performance, efficiency, and the overall capabilities of computing devices. Understanding computer architecture helps engineers design better systems and optimize software to leverage hardware capabilities.
2. What are the main components of computer architecture?
Ans.The main components of computer architecture include the central processing unit (CPU), memory (both primary and secondary), input/output devices, and the system bus. The CPU processes instructions, memory stores data and instructions temporarily or permanently, I/O devices connect the computer to the outside world, and the system bus facilitates communication between all components.
3. How does instruction set architecture (ISA) influence programming?
Ans.Instruction set architecture (ISA) defines the set of instructions that a computer's CPU can execute. It influences programming by determining what operations can be performed and how they are coded. Different ISAs may require different programming languages or techniques, affecting how software is developed and optimized for specific hardware.
4. What are the differences between RISC and CISC architectures?
Ans.RISC (Reduced Instruction Set Computer) architectures use a small set of simple instructions that can be executed quickly, while CISC (Complex Instruction Set Computer) architectures have a larger set of more complex instructions. RISC aims for efficiency and speed by simplifying instruction execution, whereas CISC focuses on reducing the number of instructions per program, potentially increasing the complexity of individual instructions.
5. How do memory hierarchies improve computer performance?
Ans.Memory hierarchies improve computer performance by organizing different types of memory (like registers, cache, main memory, and secondary storage) in a way that balances speed and cost. Faster, more expensive memory (like cache) is used to store frequently accessed data, while slower, cheaper memory (like hard drives) is used for less frequently accessed data. This structure minimizes the time the CPU spends waiting for data, thus enhancing overall system performance.
