The following content provides plagiarism-free, university-verified solutions for the Tutor-Marked Assignment (TMA) of MCS-202 Computer Organisation, designed strictly for the Post Graduate Diploma in Computer Applications (PGDCA) under the School of Computer and Information Sciences (SOCIS). Solutions are formatted for English and Hindi mediums, adhering to word limits and academic integrity standards.

Key Syllabus Blocks Covered in Solutions:

• Block-1: Data Representation and Logic Circuits
  • Binary, decimal, octal, and hexadecimal number systems with conversion techniques.
  • Boolean algebra and logic gates: AND, OR, NOT, NAND, NOR, XOR/XNOR.
  • Karnaugh maps and simplification of Boolean expressions.
  • Arithmetic circuits: ALU design, adders (half/full), subtractors, and overflow detection.
• Block-2: Memory and I/O Organisation
  • Memory hierarchy: Registers, cache, main memory (RAM vs. ROM), and secondary storage.
  • Addressing modes: Direct, indirect, relative, and segmented addressing.
  • Input/Output (I/O) devices: Types (storage, display, input), controllers, and interrupts.
  • DMA (Direct Memory Access) and its role in I/O operations.
• Block-3: The Processing Unit
  • CPU architecture: Control Unit (CU), Arithmetic Logic Unit (ALU), and registers (PC, MAR, MDR).
  • Instruction cycle: Fetch, decode, execute, and memory access phases.
  • Pipelining and its impact on CPU performance.
  • RISC vs. CISC architectures and their design trade-offs.
