Random Access Memory (RAM) is a type of computer memory that temporarily stores data and programs that your computer is currently using. It allows your computer to access information quickly, which helps it run smoothly and efficiently. When you open an application or file, it gets loaded into RAM, enabling fast access and processing. Unlike permanent storage like a hard drive or SSD, RAM is volatile, meaning it loses all its data when the computer is turned off. The more RAM your computer has, the more tasks it can handle simultaneously, making it essential for activities like gaming, video editing, and multitasking with applications like Microsoft Word or Adobe Photoshop.
