Secure Digital Card
What Is It?
A Secure Digital card (SD card) is a non-volatile form of flash memory for portable and mobile devices. Because it is not proprietary, its usage is widespread.
Importance of an SD Card
- You can add an SD card to a small device, like a mobile phone, to extend the storage space available for ringtones, texts, apps, music and other data.
- When one SD card in your camera fills up with photos and videos, you can swap it out for an empty SD card instead of deleting any files.
- You can save files to an SD card to transfer them between devices or give them to someone else.
