What is terabyte? How to use in English

The term "terabyte" originates from the International System of Units (SI) prefix "tera-," which means one trillion. In computing, the term "terabyte" was coined in the 1990s to denote a unit of digital information equal to one trillion (1,000,000,000,000) bytes. A byte is a basic unit of digital information, which is typically a group of eight binary digits. The term "terabyte" was originally used to describe large capacities of storage media, such as hard disk drives and tape drives. It was first used in the 1990s to describe storage capacities measured in亿 (billion) bytes, which was no longer sufficient to describe the exponentially increasing sizes of storage media. Today, the term "terabyte" is widely used to describe storage capacities of devices such as external hard drives, solid-state drives, and cloud storage services.
