Have you ever noticed how: Apps open instantly sometimes But the same system feels slow at other times? The reason isn’t just the processor or software. It’s how memory is organized inside your computer . Modern systems don’t rely on just one type of memory. Instead, they use a memory hierarchy — a smart arrangement of cache, RAM, and storage — each with a specific role in performance. In this post, we’ll explain this hierarchy conceptually , without technical overload, and show why it directly affects your daily computing experience. Why Computers Use Different Types of Memory Computers need memory that is: Extremely fast Affordable Large in capacity But no single memory type can satisfy all three. So operating systems and hardware designers use layers of memory , each optimized for a different purpose. This idea builds directly on how the OS manages memory efficiently. 👉 (link: How an Operating System Manages Memory) The Memory Hierarchy (Big Pi...
