"The tablet is so slow now!"

Raven counts the apps. "What do you notice?"

Nova blinks. "Hint: memory can only hold so much."

Opening an app

Tap an icon to open an app.

The instructions move from storage into memory.

Memory is where work in progress lives.

Now the processor can follow the instructions.

Closing an app

Many open apps fill up memory.

A full memory can make things slow.

Close apps you are done with.

Closing clears space in memory.

The app stays in storage for next time.
