Take a guided tour inside a computer and finally understand what the CPU, RAM, storage and GPU actually do. This lesson uses clear analogies (like short‑term vs long‑term memory) and Cornell note‑taking slides to help Grade 10–12 CAT learners build strong foundations for exams. We compare HDD and SSD storage, explain why RAM upgrades speed up a PC, and show how all the main components work together while you open, use and save files. Ideal for South African CAPS learners, teachers, or anyone who wants a clear, classroom‑style explanation without the jargon.
