Terabyte - trilobite
From Hull AWE
A terabyte is a unit of data storage which, at time of writing, is just coming into use. It is formed from the SI prefix "tera-", and is 1000 gigabytes (or sometimes 1024: see the Wikipedia article on binary prefixes ).
A trilobite is completely different: it is a now extinct animal, known only in fossil form. (Trilobites often look like woodlice.) (Again, see the Wikipedia article on the trilobite for more.)
