A gigabyte (Gb) is a unit of digital storage or computer memory equivalent to 1,024 megabytes. It is commonly used to measure the capacity of storage devices, such as hard drives, memory cards, and computer RAM.
Understanding gigabytes is important for photographers and digital content creators, as high-resolution images and videos require significant storage space. Knowing how much memory or storage a device provides helps in planning for file management, backups, and efficient workflow in digital photography.
