Final answer:
The largest unit of data is terabyte (TB).
Step-by-step explanation:
The largest unit of data is terabyte (TB).
Computer storage space is measured in units called kilobytes (KB), with one terabyte (TB) equaling 1024 gigabytes (GB), one gigabyte (GB) equaling 1024 megabytes (MB), and one megabyte (MB) equaling 1024 kilobytes (KB).
Therefore, a terabyte is larger than a gigabyte, megabyte, kilobyte, and byte.
