Can you explain a GB in plain and simple terms for me?

A gigabyte (GB) is a unit of measurement used to quantify digital information. It is equal to about one billion bytes, where a byte is a basic unit of data storage. To put it in perspective, a GB can typically store around 250 songs, a few hundred photos, or a short movie. It's commonly used to describe the storage capacity of devices like smartphones, computers, and USB drives.
