Sample Computer Architecture interview questions

1. Question: Explain the difference between CISC and RISC architectures.


  • CISC (Complex Instruction Set Computing): CISC architectures have a large set of complex instructions, with a single instruction capable of performing multiple low-level operations. These architectures often prioritize code density.
  • RISC (Reduced Instruction Set Computing): RISC architectures have a smaller set of simple instructions, each taking a single clock cycle to execute. RISC architectures typically prioritize performance over code density to better handling of computer architecture interview questions.

2. Question: What is pipelining in processor architecture, and how does it improve performance?


  • Pipelining is a technique where multiple instructions are overlapped in execution, with each stage of the pipeline handling a specific task. It improves performance by allowing the processor to execute multiple instructions simultaneously.
  • The pipeline stages include instruction fetch, instruction decode, execute, memory access, and write-back. As one instruction moves to the next stage, the processor fetches and decodes the next instruction, enabling a continuous flow of instructions through the pipeline.

Third is also an important question of computer architecture interview questions

3. Question: Describe the role of cache memory in a computer system.


  • Cache memory is a small, high-speed type of volatile computer memory that provides high-speed data access to the processor and stores frequently used computer programs, applications, and data.
  • The primary purpose of cache memory is to reduce the average time to access data from the main memory. By storing frequently accessed data closer to the processor, cache memory minimizes the need to fetch data from slower main memory, improving overall system performance.

Following one is very common among the computer architecture interview questions.

4. Question: What are the advantages and disadvantages of parallel processing?


  • Advantages:
    • Increased Performance: Parallel processing allows multiple tasks to be executed simultaneously, leading to a significant boost in overall system performance.
    • Scalability: It offers scalability, making it easier to handle larger workloads by adding more processing units.
    • Redundancy: Parallel processing provides redundancy, as multiple processors can perform the same task concurrently for fault tolerance.
  • Disadvantages:
    • Complexity: Designing parallel algorithms and coordinating parallel tasks can be complex.
    • Cost: Implementing parallel processing systems can be expensive.
    • Limited Applicability: Not all tasks can be parallelized effectively, and some may see little to no performance improvement.

5. Question: How does DMA (Direct Memory Access) enhance I/O performance in a computer system?


  • DMA is a feature that allows peripheral devices to transfer data directly to or from the computer’s memory without involving the CPU. This enhances I/O performance by reducing the CPU’s involvement in data transfer operations.
  • Instead of the CPU managing data transfers, DMA allows peripherals like hard drives or network interfaces to communicate directly with the memory, freeing up the CPU to perform other tasks. This results in faster and more efficient I/O operations.

These sample computer architecture interview questions cover a range of topics within computer architecture, testing the candidate’s understanding of fundamental concepts and their ability to articulate complex ideas.
