memory cards

Memory cards are small storage devices used to save digital data, such as photos, videos, and documents. They work by storing information electronically, similar to a tiny hard drive. Common types include SD (Secure Digital) and microSD cards, which are often used in cameras, smartphones, and tablets. They are portable, easily removable, and come in different sizes and capacities to suit various needs. Memory cards enable quick data transfer and expand the storage space of devices, making them convenient for managing large files and backups without relying on internal storage alone.
