Morphology

This is an abbreviation/initialism (Z B for zettabyte); the letters are not productive English morphemes and do not transparently convey the meaning to learners.

Etymology

ZB is short for zettabyte, where zetta- is a modern prefix like in gigabyte or megabyte that means 'very large', and byte is a unit of digital data. So, a ZB names a very, very large amount of data, which is why we use it for cloud and global storage numbers.
