memory mapping

Memory mapping is a technique where a computer connects hardware devices or certain data to specific areas of its main memory (RAM). This allows the CPU to access these devices or data directly using standard memory instructions, simplifying communication and control. Essentially, it creates a designated "address space" in memory that corresponds to hardware components, making data transfer and device management more efficient. Think of it as assigning particular "parking spots" in memory for hardware devices, so the CPU knows exactly where to read from or write to for interacting with them.
