KEN, DEN
Implementation of interrupt priory by using individual interrupt-request and acknowledge lines
Polled interrupts: Priority decided by the order in which processor polls the component (polls their status registers) vectored interrupts: Priority determined by the order in which processor tells component toput its code on the address lines (order of connection in the chain)
(a) Daisy chain
Daisy chaining of INTA: If device has not requested any service, passes the INTA signal to next device if necessitate service, does not pass the INTA, puts its code on the address lines Polled
