RAM (Random Access Memory) is a type of computer memory that temporarily stores data and instructions that the processor needs while running programs. Unlike permanent storage, such as hard drives or SSDs, RAM is volatile, meaning its contents are lost when the device is turned off. Having more RAM allows devices to handle more tasks at once, improving speed and responsiveness. It plays a crucial role in the smooth operation of computers, smartphones, and other digital devices by enabling quick access to active data and applications.
