I believe the answer is:

rom

I'm a little stuck... Click here to teach me more about this clue!

'device' is the definition.
(ROM is an example)

I don't understand how the remainder of the clue works.

(Other definitions for rom that I've seen before include "Gypsy man" , "Computer memory to read only, in short" , "Read-only memory" .)

I've seen this clue in the Evening Standard.
