SD Cards

SD cards are small, portable storage devices used to save data such as photos, videos, and documents. They function by storing digital information electronically, allowing devices like cameras, smartphones, and tablets to expand their storage capacity. SD cards use flash memory technology, which retains data even when the device is turned off. They come in various sizes and speeds, making them versatile for different needs—from casual use to professional photography. Essentially, they are a convenient, reliable way to carry and transfer digital files between devices.
