| <h1>Computer Science Batch 05 - Operating Systems - Programming Framework Analysis</h1> | |
| <p>This document presents operating systems processes analyzed using the Programming Framework methodology. Each process is represented as a computational flowchart with standardized color coding: Red for triggers/inputs, Yellow for structures/objects, Green for processing/operations, Blue for intermediates/states, and Violet for products/outputs. Yellow nodes use black text for optimal readability, while all other colors use white text.</p> | |
