Simply put, memory cards are designed whereby they are inserted into a USB port, which can be located on a digital camera, MP3 player, PDA, mobile phone, computer, and other electronic devices. In the technical world, this memory card or memory stick is “non-volatile.” This means that any information, such as documents, photos, audio, or video stored on the USB memory card will remain there whether it is plugged in or not. Even if you have the card plugged into the port on your computer or other device, the data would still be stored whether the device is powered to the on or off position.

All types of electronic devices are made to use memory cards. Depending on the device, format of data being saved, and size of data would determine the type of memory card used. For larger files, you would need something robust such as the SDHC card. However, for smaller devices or files, the micro-sd would suffice. Once the information has been saved, the memory card can be inserted into other electronic devices. For example, if you have taken photos of your vacation and want to download them to your computer to edit and then share with family and friends, you would simply insert the card into the camera, save the files to the card, insert it into your computer (with or without an adapter depending on the system), and then download. As you can see, memory cards are valuable, saving people precious time.
