Eight bits are gripping to listen to (4)
I believe the answer is:
byte
'eight bits' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for byte that I've seen before include "Set of eight bits" , "Unit of (PC) memory" , "Computer's unit of stored memory" , "Unit of memory storage in computer" , "Computer memory unit of eight bits" .)
