A gigabyte (GB) is a unit of digital information storage capacity, equal to approximately one billion bytes. It's used to measure the size of files, the storage capacity of devices like hard drives, and internet data usage. While technically one billion bytes, it is sometimes used to mean \(1,073,741,824\) bytes (\(2^{30}\)), especially in computing contexts. 

Key aspects of a gigabyte

Measurement: A gigabyte is one of many units used to quantify digital data, following kilobytes and megabytes. A terabyte is larger, equal to 1,000 gigabytes.

Usage: It's a common term for describing:

Storage: The capacity of a hard drive, solid-state drive (SSD), or other storage medium can be several gigabytes.

RAM: The amount of RAM (random access memory) in a computer is often measured in gigabytes.

Internet data: Internet service providers (ISPs) use gigabytes to track and limit monthly data consumption.
