What is RAM?

TechnologyLesson on requestFree to read

Quick answer

RAM (random-access memory) is your device's short-term working memory. It holds the apps and data you're actively using so the processor can reach them instantly. It's fast but temporary — switch off the power and it clears. More RAM lets you run more things smoothly at once.

Key things to understand

  1. The device's fast, short-term working memory.
  2. Holds what you're actively using right now.
  3. Much faster than storage (disk/SSD).
  4. Clears when powered off; more = smoother multitasking.

People also ask

What's the difference between RAM and storage?
RAM is temporary working memory the processor uses live; storage (SSD/disk) keeps your files permanently but is far slower.
Does more RAM make a device faster?
It helps you run more apps at once without slowdown; beyond what you need, extra RAM gives little benefit.
Why does RAM clear when I switch off?
It's volatile memory — it needs power to hold data, so it empties on shutdown.
