Data storage is typically measured in gigabytes (GB). A gigabyte is equivalent to approximately 1 billion bytes, and it serves as a standard unit for measuring the capacity of digital devices such as hard drives, USB flash drives, and memory cards. The gigabyte helps users understand how much data can be stored, such as documents, photos, music, and videos. As technology advances, larger storage capacities are now common, with some devices reaching terabytes (TB) and beyond.
