Computer that may be prescribed? (6)
I believe the answer is:
tablet
'computer' is the definition.
(I know that tablet is a type of mobile computer)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for tablet that I've seen before include "Handheld personal computer" , "pill needed" , "A small pill or an inscribed panel on wall" , "Prescription" , "PC" .)
