RAM (Random Access Memory) is your computer’s high-speed, short-term memory, storing data for active applications and files so the CPU can access it instantly, much like a desk holds papers you’re currently using, unlike slower long-term storage like hard drives. It’s essential for multitasking, allowing smooth switching between programs, and comes as physical modules (sticks) with different types (DDR3, DDR4, DDR5) and capacities (GB) that directly impact your system’s speed and responsiveness. Data in RAM is volatile, meaning it’s erased when the power goes off.
