Terabyte - GCSE Computer Science Definition

A terabyte is a unit of digital storage that measures the amount of data a computer device can hold. It is equal to 1,024 gigabytes, which makes it a very large amount of space. For example, a terabyte can store around 250,000 photos, 250 movies, or 6.5 million document pages. In GCSE Computer Science, understanding storage units like terabytes is important because it helps you grasp how much data devices like computers, smartphones, and external hard drives can store. Knowing this helps you make better decisions when choosing or using these devices for different tasks.
