Random Access Memory (RAM) is a type of computer memory that stores data and machine code currently being used. RAM provides fast read and write access to the system, enabling smooth performance for running applications and processes. Unlike storage memory (like a hard drive), RAM is volatile, meaning it loses its data when the computer is powered off. The more RAM a system has, the better it can handle multitasking and demanding applications like video editing, gaming, or software development. Modern computers typically use DDR (Double Data Rate) RAM, which comes in various versions (DDR3, DDR4, DDR5).
