Is there such a thing as a trillibyte on a computer?

In terms of "Bytes," we use different nomenclature than your standard descriptors of money, for example. You might have a thousand dollars, but a thousand bytes are a kilobyte. A thousand kilobytes is a Megabyte (or the equivalent to a million bytes.) A billion bytes is a Gigabyte. A trillion bytes is a Terabyte. google search "metric Prefixes" to keep going.
