Computer architecture defines the attributes of a system that are visible to a programmer and have a direct impact on the logical execution of a program.
The critical interface between software and hardware. It defines the native commands (like ADD , MOVE , or JUMP ) that the processor can understand and execute. COMPUTER ORGANIZATION AND ARCHITECTURE
The distinction between these two concepts is fundamental to understanding modern computing systems. Computer Architecture Computer Organization High-level system design and behavior. Low-level physical components and interconnections. Visibility Directly visible to the assembly programmer. Transparent/hidden from the programmer. Core Elements Computer architecture defines the attributes of a system
Focuses on rich, complex instructions that can perform multi-step operations in a single command, prioritizing smaller code sizes (e.g., x86). The distinction between these two concepts is fundamental
Focuses on simple, highly optimized instructions that execute in a single clock cycle, prioritizing speed and efficient hardware pipelines (e.g., ARM). COMPUTER ORGANIZATION AND ARCHITECTURE
