A) kilobyte (KB)
B) terabyte (TB)
C) megabyte (MB)
D) gigabyte (GB)

Accepted Answer

A terabyte (TB) is the largest unit among the options, equivalent to 1,024 gigabytes (GB), which is larger than megabytes (MB) and kilobytes (KB).

Question 12

COGNITIVE ASSESSMENT Your business is looking to rely on cloud computing services to provide system backup and the archiving of earlier versions of files, for example. What is the term for this?
