A memory card is a removable storage device used in most digital cameras to store images and videos. Common formats include MemoryStick, SmartMedia, CompactFlash, SD, and microSD cards. Capacities range from a few megabytes (MB) to several gigabytes (GB), depending on the card type and manufacturer.
Understanding memory cards is important for photographers and videographers who need reliable, portable storage for their work. Choosing the right card affects storage capacity, write speed, and compatibility with cameras, ensuring that large image files and high-resolution videos can be captured and safely stored without interruption.
