Fascinating Fact:

Storage is measured in units like bytes, kilobytes, megabytes, gigabytes, and terabytes, which show how much data can be saved.

In KS3 ICT, data storage is about how computers keep files and programs so they can be used later, even after the power is turned off. You will look at storage devices, why capacity and speed matter, and how backing up helps protect important work.

Key Terms

Secondary storage: Long-term storage that keeps data when the power is off, such as an SSD, hard drive, or memory card.
Capacity: The maximum amount of data a storage device can hold before it becomes full.
Backup: An extra copy of data stored elsewhere, used to recover files if the original is lost or damaged.

Frequently Asked Questions (Click to see answers)

What is data storage in ICT?

Data storage in ICT means saving files and programs so they can be used again later. Storage keeps data even when a device is switched off.

What is the difference between RAM and storage?

RAM is short-term memory used while a computer is working, and it clears when power is off. Storage is long-term, keeping files and apps permanently.

What is the difference between cloud storage and local storage?

Local storage keeps files on your own device, like a laptop drive or memory card. Cloud storage saves files on online servers so you can access them anywhere with internet.
