Course Overview

CIS 231 introduces students to the internal workings of a computer, emphasizing both theoretical concepts and practical implementation. The course covers:

1. Computer Architecture and Organization

Understanding the fundamental components of a computer system is crucial for programmers and engineers. Topics covered include:

• Central Processing Unit (CPU) Design – Registers, arithmetic logic units (ALU), control units, and pipelines.
• Memory Hierarchy – RAM, cache memory, and virtual memory.
• Data Representation – Binary, hexadecimal, ASCII, and floating-point representations.
• Instruction Execution Cycle – Fetch, decode, execute, and store cycle.

2. Instruction Set Architecture (ISA)

The course covers how processors execute machine-level instructions, focusing on:

• Assembly Language Instructions – MOV, ADD, SUB, JMP, CMP, and control flow statements.
• Addressing Modes – Direct, indirect, indexed, and immediate addressing.
• Stack Operations – PUSH, POP, and stack-based function calls.

3. Assembly Language Programming

Assembly language is a low-level programming language that allows developers to write programs that interact directly with hardware. In this section, students learn:

• Basic Assembly Syntax – Using labels, directives, and comments.
