How do you use a property with the units of energy per mass-temperature to model a data set?

I understand entropy in a physical sense in terms of lowering it with work input but don't see the connection here with a computer data set.

In computing, entropy is the randomness collected by an operating system or application for use in cryptography or other uses that require random data. This randomness is often collected from hardware sources (variance in fan noise or HDD), either pre-existing ones such as mouse movements or specially provided randomness generators. A lack of entropy can have a negative impact on performance and security.
