MCS-012 IGNOU Solved Assignment 2026-27

MCS-012 Solved Assignment: Computer Organisation and Assembly Language Programming

This digital PDF solution set for the Tutor Marked Assignment (TMA) of MCS-012 addresses core topics from the official IGNOU curriculum, including digital circuits, CPU design, and assembly language programming. Below are key syllabus blocks with solved answers, formatted to meet university submission standards.

Syllabus-Aligned Units Covered

• Block-1: Introduction to Digital Circuits
  • Binary logic gates (AND, OR, NOT, XOR) with truth table implementations.
  • Combinational vs. sequential logic circuits, including flip-flops and registers.
  • Solved: Design a 4-bit binary adder using full adders (word limit: 500).
• Block-2: Basic Computer Organisation
  • Von Neumann architecture and its components (CPU, memory, I/O).
  • Memory hierarchy: Registers, Cache, Main Memory, and Secondary Storage.
  • Solved: Explain the role of the Memory Management Unit (MMU) in virtual memory (word limit: 250).
• Block-3: The Central Processing Unit
  • CPU components: ALU, CU, Registers (PC, SP, AX, BX, etc.).
  • Instruction execution cycles: Fetch-Decode-Execute.
  • Solved: Trace the execution of a sample x86 instruction (e.g., `MOV AX, BX`) with register states (word limit: 100).
• Block-4: Assembly Language Programming
  • x86 assembly syntax, directives (`.data`, `.code`), and mnemonics.
  • Programming constructs: Loops, conditional jumps, and subroutines.
  • Solved: Write and explain an assembly program to compute factorial using iterative logic (word limit: 500).
