Memory (RAM) is a fast, temporary storage area the computer uses to hold data and instructions currently in use. RAM enables quick read and write operations, allowing active applications to run efficiently. When RAM is insufficient, systems rely on slower disk-based swaps, which reduces performance. RAM is volatile, meaning its contents are lost when the machine shuts down.
Why it matters
RAM directly impacts system responsiveness, multitasking ability, and application performance. Monitoring RAM usage helps diagnose performance bottlenecks, memory leaks, or application crashes.
Examples
Loading a large dataset into memory for processing or running multiple browser tabs simultaneously. Lessons like What Is RAM? provide foundational knowledge.
