RAM, or Random Access Memory, is a type of computer memory that temporarily stores data that is actively being used or processed by the CPU. It allows for quick read and write access to a storage medium, enabling fast data retrieval and efficient multitasking. Unlike long-term storage such as hard drives or SSDs, RAM is volatile, meaning that it loses its contents when the power is turned off. The capacity and speed of RAM can significantly affect the overall performance of a computer, especially in tasks that require handling large amounts of data, such as gaming, graphic design, and data analysis. In essence, RAM plays a critical role in a device's ability to perform tasks effectively in real-time.
