Questions

Question 1 (Part I) is the paper's MCQs, which are not reproduced here.

SECTION-A

  1. Q. 2
    (20)
    • (a)
      Why are multi-processor systems considered advantageous in computer architecture? How does parallel processing fundamentally improve the performance and scalability of a computer system?
      (7)
    • (b)
      How does the choice of architectural level impact the performance of a computer system? Provide a numerical comparison between two different architectural levels, highlighting their strengths and weaknesses.
      (7)
    • (c)
      If a processor executes 1 billion instructions per second and has an instruction execution cycle of 4 cycles per instruction. Calculate the overall execution time for a program with 1 million instructions. Discuss how reducing the number of cycles per instruction can impact performance.
      (6)
  2. Q. 3
    (20)
    • (a)
      Why cache memory is considered a critical component in a computer system? How does the internal and external data representation contribute to optimizing memory usage and system efficiency?
      (7)
    • (b)
      Explain the concept of parallelism in computer architecture. How does the internal structure of a microprocessor contribute to parallel processing capabilities?
      (7)
    • (c)
      Break down the stages of the instruction execution cycle in a computer system. How do the characteristics of CISC and RISC architectures influence the execution cycle?
      (6)
  3. Q. 4
    (20)
    • (a)
      Compare the OSI and TCP/IP models in terms of their simplicity and practicality. Why is a layered approach beneficial in network design?
      (7)
    • (b)
      Explain how overlay networks and content distribution networks enhance the performance and scalability of internet services? Provide a numerical example to illustrate their impact on content delivery.
      (7)
    • (c)
      If the internet were a city, and each device had its own unique street address, how does IP addressing work in this scenario? Explain the purpose of subnetting using a neighborhood analogy.
      (6)
  4. Q. 5
    (20)
    • (a)
      Compare the file systems of UNIX and Windows in terms of structure, permissions, and file organization. How do these file systems cater to the needs of diverse computing environments?
      (7)
    • (b)
      How does an operating system mediate between application programs and the computer hardware? Discuss the key roles and responsibilities of an operating system in managing resources.
      (7)
    • (c)
      What is process management in the context of operating systems? How does the operating system handle processes, and what role does it play in multitasking?
      (6)

SECTION-B

  1. Q. 6
    (20)
    • (a)
      Elaborate on the evolution of database systems, highlighting major milestones. Discuss the impact of emerging technologies on the field of database systems.
      (7)
    • (b)
      Write a SQL query involving multiple tables and incorporating JOIN operations. Discuss the potential pitfalls and optimizations related to complex SQL queries.
      (7)
    • (c)
      What are distributed databases, and why are they used? Discuss the advantages and challenges of managing data in a distributed environment.
      (6)
  2. Q. 7
    (20)

      Explain the algorithms used for point detection, line detection, edge detection, and boundary detection in digital images. Discuss the strengths and limitations of these techniques.
      (7)
    • (b)
      Provide detailed explanations and applications of morphological operators like erosion, dilation, opening, closing, skeletonization, and thinning in image processing.
      (7)
    • (c)
      Compare and contrast various image sensing and acquisition techniques. Discuss the advantages and limitations of different methods such as CCD and CMOS.
      (6)
  3. Q. 8
    (20)
    • (a)
      Develop a numerical comparison between client-side functionalities implemented using different JavaScript patterns. Discuss how these patterns impact code maintainability and performance?
      (7)
    • (b)
