This episode covers one of the most fundamental concepts in IT — the input, output, processing, and storage model — and its role in the CompTIA IT Fundamentals (ITF+) certification exam. You’ll learn how each component interacts, from the moment data enters a system through a keyboard, scanner, or sensor, to the point where it’s processed by the CPU or GPU, stored in memory, and finally presented back through a display, printer, or speaker.We’ll go beyond definitions to explore real-world examples, showing how these stages appear in personal devices, enterprise systems, and IoT environments. Understanding the relationships among these components not only helps you master exam questions but also provides a practical framework for troubleshooting and system design in any IT role.
