When shopping for a tablet, you often see specs like “4GB+64GB” or “6+128GB.” These numbers refer to RAM and ROM, two critical specifications that determine how fast your device runs and how much you can store.
But what exactly are RAM and ROM? What’s the difference, and how should you choose? Let’s break it down clearly and simply.
RAM (Random Access Memory) is the short-term memory of your tablet. It handles all the real-time tasks:
Opening apps
Switching between screens
Playing games or videos
If your RAM is too small, you might experience:
Lag and freezing
Slow multitasking
Apps crashing or closing automatically
Usage Type | Suggested RAM |
---|---|
Basic web browsing/video | 3GB or higher |
Online learning/education | 4GB–6GB |
Light multitasking/office | 6GB–8GB |
ROM (Read-Only Memory) refers to the internal storage of your tablet. It’s where you save:
Photos and videos
Apps and games
Documents
System updates
The more ROM you have, the more content you can store. If ROM is too small:
You’ll run out of space
Your device might slow down
You won’t be able to install new apps or update your system
Usage Type | Suggested ROM |
---|---|
Basic use | 32GB–64GB |
Education/entertainment | 64GB–128GB |
Heavy usage/gaming | 128GB or more |
Some people think large storage (ROM) is enough—but that’s only half the story.
RAM controls how smoothly your tablet runs
ROM controls how much content you can store
For example:
A “2+128GB” tablet may offer big storage, but with only 2GB RAM, it might run slowly.
A “4+64GB” device often delivers a better user experience overall.
Balance matters.
