Which item is commonly used as portable storage in cameras?

• A. RAM
• B. ROM
• C. SATA
• D. SD card

Answer: (D)

Removable flash memory used to store photos and videos is the concept here. Cameras generate large files and need a compact, durable, and easily swappable storage medium. An SD card fits this role perfectly: it’s small, widely supported by cameras, and offers fast enough read/write speeds for high‑resolution images and videos. RAM, by contrast, holds data only while the device is powered and isn’t used for long-term storage. ROM contains firmware and fixed data, not user media storage. SATA is an internal interface for drives inside a device, not typical removable camera storage. So the item commonly used as portable storage in cameras is the SD card.
