Computer Basics•Lesson 4
RAM vs Storage
Learn the concept, follow the practical steps, and apply what you learn through a simple activity.
RAM and storage are not the same thing. RAM is fast working memory used while programs are running. Storage keeps files and programs after the computer is turned off.
RAM
When you open a browser or document, the operating system loads working data into RAM. RAM is volatile memory, so its contents are normally lost when power is removed.
Storage
An SSD or HDD stores the operating system, applications, photos, videos and documents. Storage is non-volatile.
RAM vs storage
| Feature | RAM | Storage |
|---|---|---|
| Purpose | Active working data | Long-term data |
| Power off | Normally loses contents | Keeps data |
| Examples | DRAM | SSD / HDD |
Practice
Open your system monitor, note memory use, then open two or three applications and observe the change.
Key takeaway
RAM is working space; storage is long-term space.
